Disable link with javascript

In JavaScript, you may encounter a situation where it is required to disable a specific link in case of an update in the website content or when there is heavy traffic on a specific site to be accessed or maintaining a website or web page. In such scenarios, disabling links can be helpful for the developers and users as it saves a lot of time on both ends.

This article will guide you about Disabling Links in JavaScript.

To Disable Links in JavaScript, you can apply:

We will now go through each of the mentioned approaches one by one!

href” is an attribute of the anchor tag used to identify sections within a document. It can be used to return an “undefined” value by placing a null value “void(0)” in the “URL” to disable the link in JavaScript.

Here, “URL” refers to the website resource for opening a web page and adding “void(0)” will disable it.

Look at the below-given example.

Example
In this example, we will place the href in the “ ” tag. Now, we will return an undefined value by setting href to “https://www.youtube.com:void(0)”:

The output of the above implementation will result in:

In JavaScript, the “addEventListener()” method attaches an event handler to a document. We can utilize this method to add an event “click” and then disable the provided link by “preventDefault()” at a specific condition which will prevent the triggering of the added event.

Here, the parameter “event” refers to the event type, and the parameter “function” is the function we want to access whenever the event occurs.

Look at the following example for a better understanding of the concept:

Example
Firstly, we will place the webpage link in the anchor tag of the “href” attribute. Here, “id=home” will open the homepage of youtube and the “blank” target will open the specified webpage in the new tab:

Next, we will access the href attribute value by passing it as a parameter to the “document.getElementById()” method. Now, we will include a “click” event and the function we want to access whenever the event occurs. Finally, a condition is applied in such a way that if the specified web page triggers as the click event, the event is disabled by the “preventDefault()” method:

< script >
var link = document. getElementById ( ‘home’ ) ;
document. addEventListener ( ‘click’ , function ( e ) {
if ( e. target . id === link. id ) {
e. preventDefault ( ) ;
}
} ) ;

The corresponding output in this case will be:

We have provided all the simplest methods to Disable Links in JavaScript. You can use any of the explained methods according to your requirements.

Conclusion

To disable links in JavaScript, you can apply the “href” attribute method for returning an undefined value by placing the null value “void(0)” in the “URL” placeholder or utilize the “addEventListener()” method for adding a click event at the specified URL in the href attribute and then disabling it on a specific condition. This write-up explained the methods to disable links in JavaScript.

Disable Links in JavaScript

  1. Set href to Different Functions to Disable Links in JavaScript
  2. Use the addEventListener() Method to Disable Links in JavaScript
  3. Use the name Attribute to Disable Links in JavaScript
  4. Use jQuery to Disable Links in JavaScript

JavaScript conventions add a more efficient way to disable an anchor tag href . Usually, we can set the href=»#» to ensure that a link is not routing to any address.

Also, there is the JavaScript function way to define an empty allocation such as href=»javascript:void(0)» . Again, we can also state href=»javascript://» , meaning the value is null.

In the following segment, we will see how we implement disabled links without JavaScript and make an efficient approach with JavaScript that is more meaningful. We will use the addEventListener() method, name attribute, and the jQuery way of disabling a defined link.

Set href to Different Functions to Disable Links in JavaScript

Here we will disable links only by setting the href to get null values. This is not the best way to imply the concept, as you often need the alteration of enabling and disabling a link.

So, keeping the href always empty requires hard coding the links in every modification.

html> head>  title>Disable linktitle>  head> body>  p>Disable linkp>  a href="javascript://" id="home">Youtubea>br>  a href="javascript:void(0)" id="home">Googlea>br>  a href="#" id="home">Gita>br>  body>  html> 

javascript:// , javascript:void(0) , and # evaluate the href to have a null or undefined result. Consequently, we get a disabled link, but there are ways to perform this task better.

Use the addEventListener() Method to Disable Links in JavaScript

We will have an anchor tag having the home page of Google linked. If we wish to disable the link, we will manually define some conditions in the JavaScript section.

This will make the path of alteration easier. So, an eventListener() will get triggered every time the link is clicked.

The function will prevent the default activity on clicking the link, which is to route to the actual page that is linked.

html> head>  title>Disable Link using JavaScripttitle>  head> body>  p>Disabled Link using JavaScriptp>  a href='https://www.google.com/' id='home' target='blank'>Googlea>  body>  script>  var link = document.getElementById('home');  document.addEventListener('click', function (e)   if (e.target.id === link.id)   e.preventDefault();  >  >);  script>  html> 

In this example, we will focus on the name attribute. The basic task is to enable an eventListener() , but the condition check this time will be with the name attribute.

As you will see, commenting the e.preventDefault(); will cause to route to the actual site. So, this is one way of disabling the link by setting the preventDefault .

html> head>  title>Disable Link using JavaScripttitle>  head> body>  p>Disabled Link using JavaScriptp>  a href='https://github.com/' target='blank' name="git">GitHuba>  body> script>  document.addEventListener('click', function (e)   if (e.target.name === 'git')   e.preventDefault();  >  >);  script>  html> 

The jQuery doesn’t perform something different from the task we already have examined. But the syntax is a bit different.

Here, we will not use the preventDefault() method. Instead, we will return a boolean value false every time the link is clicked.

This will successively disable a predetermined link.

html> head>  title>Disable link using jQuerytitle>  script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">script>  head> body>  p> Disabled link using jQueryp>  a href="https://www.youtube.com/" id="home" target="blank">Youtubea>  body> script>  $(document).ready(function ()   $('#home').click(function ()   return false;  >);  >);  script>  html>

Unlike HTML form input controls, there is no disabled attribute for the &lta> tag. Therefore, simply adding the disabled attribute to the link won’t actually disable it. There is a workaround though. You can use the DOM addEventListener() method in JavaScript to prevent it to perform its default behavior and there is also a simple method in jQuery.

Links are useful for navigating a website and why would anyone want to disable it, depends on a situation. I have seen this kind of behavior on bank portals. In such cases, you can simply remove the page link from the &lta> tags href attribute. However, if you want to do this dynamically, on special occasions, try these examples.

Disable &lta> tag in JavaScriptusing DOM addEventListener() Method

The DOM addEventListener() method attaches an event handler to the document. We can use this method to prevent a link from opening a page.

<html> <head> <title>Disable Link using JavaScript</title> </head> <body> <p>The below link is disabled using JavaScript</p> <a href='https://www.encodedna.com/' target='blank'>Home</a> </body> <script> var lnk = document.getElementById('home'); if (window.addEventListener) < document.addEventListener('click', function (e) < if (e.target.id === lnk.id) < e.preventDefault(); // Comment this line to enable the link tag again. > >); > </script> </html>

The addEventListener() method returns the element (e) when clicked anywhere on the document. When a user click’s our Home Link, the listener checks the id and prevents the &lta> tags default behavior that is opening the specified link.

You can use the name attribute too. For example, if the hyperlink has a name attribute like,

<a href="https://www.encodedna.com/" name="theHomePage" target="blank">Home</a>

then your if condition should be,

if (e.target.name === 'home') < e.preventDefault(); >

If you want to disable multiple &lta> tags or hyperlinks on a web page, you can simply use the nodeName property of the element, like this …

if (e.target.nodeName === 'A') < e.preventDefault(); >

Using jQuery to disable &lta> tag

With jQuery, you can use the click handler, which will return a false when someone clicks the link. Its like saying, do nothing when this link is clicked.

In the above example, I am using the id as selector. You can the a as selector when you want to disable all the links on a web page, like this.

As usual, the jQuery methods are less complicated and straightforward. However, if you want to avoid using a library, then I would recommend using the first example above that uses a simple JavaScript method.

Well, that’s it. Thanks for reading. ☺
