How can I disable JavaScript click function if link starts with #?
For this, use preventDefault() in JavaScript. Following is the JavaScript code −

<!DOCTYPE html>
<html lang="en">

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<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>
