How can I disable JavaScript click function if link starts with #?

Javascript Web Development Object Oriented Programming

For this, use preventDefault() in JavaScript. Following is the JavaScript code −

Example

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<a href="urlLink">Press Me to see logs</a>
<a href="urlLink">Press Me to see logs in console</a>
<a href="#">Nothing will happen</a>
<script>
   $(function(){
      $("a:not([href='#'])").click(function(event){
         event.preventDefault();
         console.log("You have pressed me!!!!!");
      });
   });
</script>
</body>
</html>

To run the above program, save the file name anyName.html(index.html) and right click on the file. Select the option Open with live server in VS code editor.

Output

If you click the two links, Press Me to see logs and Press Me to see logs in console, then you will get the console output. However, if you will click on link Nothing will happen, then it won’t print anything −
