jQuery is a popular JavaScript library that simplifies HTML DOM traversal, event handling, and AJAX interactions for rapid web development. It offers a wide range of built-in functions and methods that help developers to manipulate HTML elements, styles, and behaviors dynamically.

In this article, we will see how to select all links inside a paragraph using jQuery. Selecting links inside a paragraph is a common requirement when we want to modify the links in a particular section of our website, such as changing styles, finding links, etc.

How to select all links inside the paragraph?

Selecting links inside the paragraph is a common task and therefore there are multiple ways through which we can select all links inside a paragraph in jQuery. Let’s see some of the different approaches by which we can select links and see how jQuery can do this task effectively and write more efficient and maintainable code.

Approach 1: Using .children() Method

The .filter() method is a method provided by jQuery that allows the users to return all the direct child elements of the selected element. For selecting our links inside the paragraph that contain anchor tags y specifying the tag names, we can use the children method. Below is the syntax for achieving the same.

Syntax $("p").children("a").each(function() { }); Example

$(document).ready(function(){ $(“span”).children(“a”).each(function(){ $(this).css(“color”, “violet”); }); }); }); .find-link-class { color: black; font-weight: bold; } learning material on technical and non-technical subjects.

Approach 2: Using .filter() Method

The .filter() method is a method provided by jQuery that allows the users to filter the selected elements based on a specific condition. For selecting our links inside the paragraph that contain anchor tags and then retrieving those tags, we have to define the tag name in the filter() method. Below is the syntax for achieving the same.

Syntax $("p").find("*").filter("a").each(function(){ });

The syntax given above first selects all the paragraph elements with the help of the ‘$’ function. After this, it calls the find() method on each paragraph element for retrieving all the anchor tags that are descendants of it. Lastly, filter() method is used to iterate over each link using each() method and select only the anchor i.e., tag to add or change the styles, or to do any other action.

Example

$(document).ready(function(){ $(“p”).find(“a”).each(function(){ $(this).css(“color”, “green”); }); }); }); .find-link-class { color: black; font-weight: bold; } learning material on technical and non-technical subjects.

Approach 3: Using .has() Method

The .has() method is a method provided by jQuery that allows the users to select elements that have a certain descendant element. For selecting our links inside the paragraph that contain anchor tags and then retrieving those tags, we can use this method. Below is the syntax for achieving the same.

Syntax $("p:has(a)").find("a").each(function(){ });

The syntax given above first selects all the paragraphs that contain anchor tags with the help of :has() selector. After this, it calls the find() method on each paragraph element for retrieving all the anchor tags that are descendants of it. Lastly, each() method is used to iterate over each link to add or change the styles, or to do any other action.

Example

$(document).ready(function(){ $(“p:has(a)”).find(“a”).each(function(){ $(this).css(“color”, “red”); }); }); }); .find-link-class { color: black; font-weight: bold; } learning material on technical and non-technical subjects.

Conclusion

Selecting links inside a paragraph is a very easy task as it helps in modifying the links of a particular section of our web application. We discussed different ways for selecting all links inside a paragraph using jQuery. As discussed, we learned the three different approaches, namely using the .children() method, .filter() method, and .has() method because all of these ways are efficient and easy to use. Overall, jQuery is a powerful tool that simplifies HTML DOM traversal, event handling, and AJAX interactions for rapid web development.

How To Delete Old Facebook Posts In Bulk. (Select All Delete Posts From Facebook)

If you are looking for a way to delete all of your old Facebook posts without having to scroll through them one by one, deleting them all individually. This article will show you an easy way to automate the process, allowing you to set and forget the task until it is complete.

How to Delete Facebook Messages in Bulk.

Most people who have a Facebook account have probably thought about deleting old posts from the service, only to find that there isn’t an option to do so in bulk. This is because Facebook’s revenue stream is reliant on your data, so making it as hard to delete as possible is in their best interest.

Officially the only way to delete posts from Facebook is to do so one by one, which for a lot of people is a major deal breaker, in turn forcing them to give up on the idea. This concept didn’t bode well with me, so in 2023 I spent 30 minutes a day over several weeks manually deleting Facebook posts from my account which dated back to 2008. Thankfully! As I recently discovered, it doesn’t have to be that difficult anymore, there is now an extension that will handle the entire Facebook post deletion process automatically.

How Do You Delete Old Facebook Posts in Bulk? (Mass Delete Facebook Posts)

Delete: Deletes all the posts from your account forever.

Hide/Unhide: Will hide or unhide posts on your Timeline.

Unlike: Will unlike any and all Timeline content you may have liked in the past.

Backup: Will download a backup of your entire Timeline. Personally, I wouldn’t use this option from the extension and instead use the official Facebook account backup/download tool.

The most important thing on this page after selecting your desired option and time frame is the speed. Make sure you choose the slowest speed possible. If you choose to run Social Book Post Manager at the fastest speed, it won’t remove all the content. This isn’t any fault of the extension and is entirely Facebook related, as Facebook filters posts it shows on your Timeline it won’t always show everything….

Note: Even when I was sure I had manually deleted everything, I would still occasionally find something Facebook didn’t show me. Even after an entire year of showing everything as deleted, Facebook found an old post it missed…

Once you have set all your parameters, you can start the process, which will need to run in the background for quite a long time. If you have years of posts to remove, I would suggest starting it before you go to bed and checking in the morning. When the process has finished, you may still have content left behind, if you do, simply run the scan again, and again until it is all gone.

Note: There will be some content that can’t be deleted (by the tool or manually), with this content, you will have to use the hide option. Personally, I would just go through and manually hide any of this content after the delete scan has completed, rather than running the hide scan.  

How To Use Jquery Getjson()?

Introduction to jQuery getJSON()

JSON stands for JavaScript Object Notation. JSON is very popular for the way to exchange data and by using this we can display, style, and modify the data. getJSON () method in JQuery is used to load or to get the JSON encoded data. In some of the cases when we request the server it will return the JSON string. The resulting string will be available to the callback function of the getJSON () method. The getJSON () method will be using the GET HTTP request. In simple words, getJSON() method is used for getting the JSON-formatted data.

Syntax and Parameters

Syntax: 

$(selector).getJSON(url[, data][, function])

Parameters:

It takes three parameters. The details of the parameters are:

URL: It is of string type and it is mandatory to give or send the URL to the getJSON () method. In this, we will specify the url to which it has to send the request for.

Data: It is of string type or the plain object and it is an optional parameter. In this, the request it will be sent to the server.

Function: It is an optional parameter. It is a function that will get executed if the request is successful. It again consists of three additional parameters. They are data, status, and xhr.

Data: It is of the plain object type. The data which is returned from the server will be here.

Status: It is of string type. It contains the text status. It may be success, error, notmodified, timeout, or parsererror.

Xhr: It is of jqXHR type. It contains the XML HTTP Request. It has jqXHR.done() it indicates the success. The jqXHR.fail() it indicates error and it has jqXHR.always().

How to use jQuery getJSON()?

Before we call the getJSON () method the URL which we need to send to the method for that we need to create the json file.

We need to first install npm.

To install npm we need to execute this command in the command prompt : npm install –global json-server

After executing the above command we have to create and name the file and save the file as filename.json. (filename can be anything according to your requirement.)

After saving the file execute the following command in the command prompt:

Json-server –watch filename.json

By following the above procedure I have created a file and named it is as db.json.

The content present in the chúng tôi file is as follows:

Code:

{ "posts": [ { "id": 1, "title": "json-server", "author": "ABC" } ], { "id": 1, "postId": 1 } ], "profile": { "name": "Raju" } }

Now we are using this URL in our program. How we are using this URL in the getJSON () method and how we are getting data will be shown in the below examples.

Examples of jQuery getJSON()

Following are the example are given below:

Example #1

This is a simple example of the getJSON () method. In this example, we can observe how the getJSON () method will work.

Code:

$(document).ready(function(){ $.each(event, function(i, value){ $(“div”).html(value); }); }); }); }); Example for the getJSON() method

Output:

In the above program we can observe that we have passed the URL to the getJSON () it will be redirected to the file which we have created and gets the data from the file.

Example #2

This is another example of the getJSON () method.

Code:

$(document).ready(function(){ $.each(event, function(i, value){ $(“div”).append(value + ” “); }); }); }); });

Output:

Example #3

Code:

$(document).ready(function() { }); }); }); Example for the getJSON () method

Output:

We can see in the above code we have passed this URL to the getJSON () method. So it will get the data displays the content in the output.

These are some of the example programs which will help you to understand the getJSON() method.

How To Select The Right Placements For Your Display Network Campaign

This article will share three techniques to generate relevant traffic on display campaigns, each focused on a different level of effectiveness.

Level 1: Poorly Effective – Long Term Results

Now, you need to link AdWords to Analytics via AdWords. You need to have access to an email address that is linked botF to AdWords and Analytics and log in AdWords.

You will now be able to successfully link the accounts.

Once you complete the linking process, you will be able to use two new columns in evaluating the performance of your ad groups: Bounce Rate and Average Time On Site. These statistics will be very useful in applying an optimization process focused on pausing ad groups having a low average time on site or a high bounce rate.

Once you get rid of completely useless ad groups and identify the ones that are worth keeping, you can start tuning up bids, placements and keywords in order to tune up performance. You won’t be able to analyze avg time on site and bounce rate at the keyword and placement level on a display campaign and therefore you will need to look at changes of these metrics at the ad group level to spot potential improvements and optimize accordingly.

Level 2: Medium Effectiveness

I do not highly recommend the first approach for new accounts. It might make sense if you are desperately looking for more traffic but it can be expensive and ineffective at first.

Secondly, you need to be aware that Google allows you to select interest and topics to narrow down the placements retrieved by your keywords. This makes ensures you won’t show up for irrelevant topics or topics you are not interested in. You can also decide to exclude site category options, display keywords, age range, placements, age, interests, and a gender you do not want to show up for.

Finally, you can use the display planner tool to select relevant placements you want to appear on as long as you filter their content with your keywords, interests and topics.

Now that we have set the ground up, it is time to explain how to set up the three steps we need for our level 2 strategy:

Selecting The Proper Keywords

This is similar to what we did in Step 1. You need to make sure to organize your keywords in extremely relevant ad groups. Do not worry about match types, the display network won’t bother with them. It uses keywords only to give a context

Selecting Topics And Interests

You will now be able to set up your targeting accordingly.

Exclude What You Do Not Want to Show up For

The process is fairly easy, similar to adding the targeting settings you want, but just thinking about it the other way around and inserting the information in another section of your AdWords account.

You can access the exclusion section of your ad groups from the same section that you used for the positive targeting by just scrolling down a bit:

Select Relevant Placements Using The Display Planner

You will now need to enter some ideas of what your customers are interested in, select the landing page (optional), and campaign targeting. You can also find top placements by location or experiment with other targeting options.

You can select the criteria to sort placements and also create a custom plan to download and eventually apply to your ad groups:

Level 3: Extreme Effectiveness

In order to get started with the creation of the custom placement lists simply go to Google and search for terms potential customers will look for while deciding what brand to go for.

Additionally,you can also search for the same keywords on YouTube and create a list of YouTube placements. Keep the YouTube campaign in a separate ad group from the website placements in order to manage them separately.

You won’t need any keyword, interest, or topic targeting with this method because you are being extremely targeted in terms of placements and therefore there is no need to narrow it down.

You’re Not Going To Get The Links If You Don’t Do The Work

Lately I’ve had a thought burning in my mind – what’s the point of the title ‘SEO’. Obviously, it implies that we’re able to optimize sites for search engines, and (hopefully) gain clients’ sites visibility within search engines.

Right?

Why then, when we SEOs know Google still definitively uses links as a key metric for ranking, are we so afraid to touch them?

Shouldn’t this be a big concern for us? If we’re the professional optimizers, how can we not optimize such a key component? And yet, more and more, you see SEOs leaving behind the optimization portion and aim for more extended goals. Get traffic, build content, improve conversions, increase social, build brands.

Great goals, and certainly something that shouldn’t be ignored. But what happened to the optimization? Is it over? Is it dead? Or has search engine optimization, and link building especially, become harder?

I think there can be no doubt that as time has gone by Google has increasingly made it harder to build links. But building great links hasn’t gotten any harder. High quality, relevant, authoritative links have always been hard. Nothing new there – Google’s only yanked the rug out from under spammy link building tactics.

So is SEO itself worth still pursuing, or is it more important to focus on the marketing principles that more and more SEOs are flocking to?

Honestly, I don’t think the two should be mutually exclusive. I believe there’s a real need for both optimization and marketing. Things such as brand building, resource building, conversion optimization, and general marketing truly are important.

But true search engine optimization is just as vital for websites – and that most certainly includes pursuing link building.

Link earning versus link building

Links continue to drive conversation within the SEO world. Google’s crack down on spammy links has caused the expected ripple throughout the community – and now link building is often discussed as ‘link earning’.

But let me ask you a serious question, before I go on. Take a moment and truly think about it. What is the difference between ‘link earning’ and ‘link building’?

Have it in your mind?

Link building implies manual action. Someone is taking purposeful action in order to acquire a link.

Link earning implies a link that has been acquired by creating something worth sharing.

I can see why link earning has become a popular term – it’s what Google promotes, and helps a site doubly; a valuable, sharable resource has been created for the website that will now receive shares, which will probably go beyond just links. Meanwhile, manually building a single link often only results in just the link.

So link earning is great, in an ideal world. Unfortunately we live in the real world, and have to face reality (or the internet version of it).

The sad fact is that 99% of websites don’t have the audience engagement necessary to ‘earn links’. Hell, make that 99.99999%

Real link building has always been based upon added value, and then manually pursuing optimized links for that piece of added value, whether it takes the form of a resource, a guide, a video, or even a product (yes products can add value).

If you’re not working to optimize (eh hem, SEO) your content, including link building, then odds are you’re missing out on serious opportunities. Odds are, your content isn’t faring as well as it should. And in reality, you’re not much of a marketer, because you’re leaving real opportunities on the table. Opportunities that start with optimization via link building.

I mean, even content marketing has marketing in the title. And if you’re not acquiring links in your online marketing, you’re not working effectively.

Getting links takes work

Acquiring links takes work. This is twofold – first, creating something worthy of links, and second actually receiving the links.

First, an obligatory head nod to Rand’s “my publish button is my link building strategy” (that’s a paraphrase).

In reality, most websites don’t have any kind of following. And even if they do, it’s still hard to receive the links they should.

The SEO industry is probably one of the most equipped (and likely) industries to actually give editorial links.

Think about the process of acquiring a great link 100% naturally:

Create something really great worth sharing

Have a built up community that follows your content

Have the relevant audience that your content resonates with

Have a portion of that audience actually own websites

Have a portion of the audience that own websites be in control and managing that site, actively

Have a portion of the audience that owns and manages a site engaged enough to go to the effort of linking to your content

A portion of those will link in a manner that will have a strong SEO impact

Pretty simple, huh?

Or you could do the work required to actually required to build quality links. Work naturally suited to content creation such as:

Identify your target audience

Recognize a need

Clearly define the purpose and goals of your content/resource

Create a target list of link/promotional opportunities

Reach out to that list in a personable manner

Follow up as needed

And, while you’re at it, you could attempt to build a relationship and foster community engagement.

Building a relationship doesn’t mean you need to become best friends or even chat every week with anyone who responds positively to your outreach. In reality, just make sure you’re engaging in the community of your peers and targeted audience. That’s all.

Do Links Still Matter?

It is my firm opinion that you’ll never get (build, earn, acquire, whatever you want to call it) links effectively without putting in the work.

There are, as always, a few exceptions to the rules. Websites that have managed to build a large cult following, and have a continually active and engaged audience. But for the average website—not to mention an ecommerce site—links don’t flow naturally.

So that leaves us with one question – do links still matter?

There can be no doubt they have in the past.

And, as Matt Cutts recently stated, links are still the best signal of authority and relevance Google has.

So to Google, they do. Should they to webmasters everywhere? Well, if those sites care about Google, I’d say it’s a safe bet.

Will social, authorship, citations, and the 200+ other signals Google has erode the effectiveness of links with time?

Perhaps, but it’s going to be quite a while before I would expect to see this be the case, and even then links will more than likely be a strong signal to Google.

Google is like the Titanic – they’re so large that even a slight course change can send waves through the entire web, not to mention the SEO community. But are they able to do a 180 degree turn with any speed? No.

Links are, and will continue to be, a very important factor into online visibility.

Links are after all the very foundation on which Google as a search engine was built.

Inside The Shadowy Underground Of Korean Monitor Sales

If you’re in the market for a new high-definition desktop monitor, take note: You may be able to pick up a very good Korean-made display for far less money than what you’d spend on, say, an Asus, Dell, HP, or Samsung model. Sure, you’ll have to cope with odd product branding, limited functionality, and less-than-inspired product design; but if your primary concern is image quality, a Korean display purchased on eBay could be just the ticket.

On eBay I found numerous small Korean resellers offering 27-inch, 2560-by-1440-pixel monitors at fantastic, sub-$400 prices. And many of them listed high buyer satisfaction rates, which eBay buyers generate themselves.

You can find hoards of monitors with IPS 2560-by-1440 panels on eBay.

I was still skittish about buying a monitor from an overseas source: Even if a reseller’s customer support is excellent, shipping a defective monitor back to Korea isn’t a low-cost endeavor. Then I noticed that some of the resellers were offering “perfect pixel” guarantees. Those weren’t enhanced warranty exchange programs, however. Instead, “perfect pixel” meant that the reseller opened the box, connected the display, and visually inspected it; the reseller would ship only those monitors without hot or missing pixels.

So I decided to take the plunge. But whom to buy from? And which specific display should I choose?

Putting my money where my mouth is

When you search eBay for one of these Korean IPS displays, you won’t find familiar brands such as LG or Samsung. Instead you’ll be looking at something from Imon, Shimian, or Yamakasi. Yes, these are not household names.

Clearly, most of these items are actually private labels, because they’re all quite similar. I found some monitors that cost less than $300, but typically they were untested displays with a single DVI dual-link connector. Most of the least-expensive displays don’t support HDCP content protection, so if you should want to play Blu-ray movies or other protected content from set-top boxes, you may be out of luck.

You can find units with additional features, such as HDMI and DisplayPort support, but the costs then rise to a little over $400. Even then, you’ll encounter limitations. HDMI inputs, for example, may not support the higher-bandwidth HDMI 1.4a standard, so output resolution will be limited to 1920 by 1080 pixels when you connect the monitor via HDMI. Units with HDMI 1.4a support rise to almost $500.

All I wanted was another LCD monitor for a gaming system I have in my basement lab, so I didn’t really need bells and whistles such as HDMI connectors and built-in speakers. Eventually I settled on a Shimian QH270-Lite from a vendor called “ta_planet”. The net cost was $363.95, which included an extra $10 for the “perfect pixel” guarantee. That cost also included FedEx shipping from Korea. So all in all, I considered it a good deal. This is the 27-inch Shimian monitor I bought on eBay.

About an hour after placing the order, I received an eBay message from ta_planet telling me that the monitor was out of stock. But the message also said that ta_planet would be happy to ship an alternate display with built-in speakers at no extra charge, and with the “perfect pixel” guarantee intact.

I immediately filed this in my “too good to be true” mental folder. “Uh-oh,” I thought to myself. “Here it starts. I’m going to get a piece of junk.”

I thought about the problem for a few hours, and then responded to ta_planet via eBay messaging, accepting the offer. Within 10 minutes I received a response declaring, in effect, that ta_planet had received a new shipment of the QH270-Lites, and would be shipping one of those out to me per the original order.

My new monitor, in pictures (or, the $364 question)

A few days late, a fairly slim box arrived via FedEx. It came complete with weird stickers and customs documents. The Shimian QH270-Lite display seems fairly stock in other ways. The glossy surface is a little annoying, but, hey: $364! The controls are small buttons built into the right rear surface of the chassis. You can see the icon for the brightness (backlight) control. The two buttons adjacent to the sun icon dim or brighten the display. Out of the box, the screen is way too bright. Those other buttons? They do nothing. They’re probably there for higher-end versions of the display that have built-in hardware scaling. The back of the unit also has speaker grilles, even though this display has no speakers.

As expected, the display is DVI dual-link only. You must use dual-link to hit the bandwidth necessary for 2560 by 1440 resolution, anyway. A dual-link DVI cable was included in the package.

One key limitation of this $364 display is its stand—one of the worst I’ve seen on an LCD panel. It sits very low to the desk, and offers zero adjustments. Fortunately this stand—salvaged from an old, nonfunctional Gateway display—connected via a plate that attaches to the VESA mount. If I didn’t have this stand, I’d have to live with the crummy included stand, or spend $30 to $100 or so for a more ergonomic stand. Be sure to factor that into your cost estimate if you’re pricing one of these monitors. Some of the more expensive displays I saw on eBay seemed to come with better stands.

I made some interesting discoveries when I unboxed the monitor. It uses an external, switching power brick that can run in either 220-240V or 110-120V mode. As with most of these bricks, one end is a standard three-pin, capable of accepting most power cords. However, only a Korean power cord came in the box, so I had to dig up a standard cord with U.S. plugs.

No documentation or CD accompanied the monitor, but that didn’t surprise me much.

Bottom line: Fire it up!

Finally, it was time to stop scrutinizing the aesthetics of the display and actually use it. I connected the DL-DVI cable to a system running a Sandy Bridge Core i7 CPU and an Nvidia GTX 580 graphics card. I checked out all-white images and all-black images to see if the display had issues with individual pixels. Careful examination revealed no hot or missing pixels. The black image exhibited a small uniformity problem, though: In full black mode, the backlight in the lower right of the display was a touch brighter than the rest of the display. But it was hard to spot unless I was looking for it.

It lives!

I wouldn’t recommend this kind of monitor for intensive photography work or video editing. Although you can, in theory, calibrate the display, the backlight hotspot is probably a negative for any serious task. Also, since the display has no built-in hardware for scaling the video, you’re at the mercy of the graphics card and driver when it comes to video rendering quality. For instance, on my screen, HD video from Netflix streaming looked very soft, whether at 2560 by 1440 or 1920 by 1080.

You can spend up to $150 for additional features, such as video scaling and high-bandwidth HDMI. But my QH270-Lite has acquitted itself well as a standard desktop monitor, and it certainly handles games with aplomb. Maybe I was just lucky. Quite a few users have bought such displays from a variety of Korean resellers on eBay with good results. But others have received very poor displays, with plenty of dead pixels. It pays to research the vendors, and it’s worthwhile to hand over a few extra dollars for a perfect pixel guarantee.

Don’t want to take a chance on eBay and on Korean shipping? Some of these monitors are starting to show up at resellers in the United States. For example, Microcenter is offering a display labeled the Auria EQ276W for $399, and it seems quite similar to these Korean displays. You can also buy from Amazon resellers, though they tend to ship directly from Korea.

What this experience really illustrates is how international tech buying has become. In one sense, purchasing a Korean monitor is like buying a gray-market product. However, gray-market products are typically brand-name gear intended for overseas customers but sold into the United States instead, whereas these monitors are purely local Korean brands. If you do find one at a nearby source, you may get better support. Wherever you shop, be aware of the risks. If you can’t afford to lose $300 to $400, you might not want to take a chance.
