How to Prevent Page Scrolling to Top on JavaScript Link Click:

When triggering a JavaScript event from a linked element, such as an anchor tag, it's common to encounter the issue of the page jumping to the top after the event fires.

Solution:

To prevent this unwanted behavior, it's necessary to suppress the default action of the click event. This can be achieved using two methods:

1. event.preventDefault():

By calling the .preventDefault() method on the event object passed to the event handler, you can prevent the default behavior of navigating to the link target.

Example (jQuery):

$('#my-link').click(function(event) {
  event.preventDefault();
  // Your JavaScript code here
});

Example (DOM):

document.getElementById('my-link').addEventListener('click', function(event) {
  event.preventDefault();
  // Your JavaScript code here
});

2. return false:

In jQuery, returning false from an event handler will automatically call both .stopPropagation() and .preventDefault() methods.

Example (jQuery):

$('#my-link').click(function(event) {
  // Your JavaScript code here
  return false;
});

If using raw DOM events, it's recommended to explicitly call .preventDefault() for maximum compatibility with older browsers. Refer to the documentation on event.preventDefault() vs. return false for details.
