What methods can I use to prevent the page from reloading in a HTML "menu dropdown" using JQUERY?

<button class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button" aria-expanded="true">
        <span class="visible-sm-inline visible-md-inline visible-lg-inline">Sort by</span>
        <span class="visible-xs-inline"><i class="fa fa-fw fa-sort"></i></span>
        <span class="caret"></span>
    </button>
<ul class="dropdown-menu pull-right">
        <li><a href="#" class="newest_to_oldest" data-sort="newest_to_oldest"><i class="fa fa-fw"></i> Newest to Oldest</a></li>
        <li><a href="#" class="oldest_to_newest" data-sort="oldest_to_newest"><i class="fa fa-fw"></i> Oldest to Newest</a></li>
        <li><a href="#" class="most_posts" data-sort="most_posts"><i class="fa fa-fw"></i> Most posts</a></li>
        <li><a href="#" class="zero" data-sort="zero"><i class="fa fa-fw"></i> Post senza risposta</a></li>
    <li><a href="#" class="most_views" data-sort="most_views"><i class="fa fa-fw fa-check"></i> Most Views</a></li></ul>

I am encountering an issue where I need to detect a click event on a specific element within the above code snippet:

<li><a href="#" class="most_views" data-sort="most_views"><i class="fa fa-fw fa-check"></i> Most Views</a></li></ul>

The problem arises because upon clicking this element, the page reloads, preventing me from executing my desired operation. Ideally, I would like to perform my operation upon clicking the element and then have the page reload. However, I am unsure if this is achievable. The jQuery code I have tried using is as follows:

$('a[data-sort]').click(function() {
  console.log("CLICK DAT SORT");
  if ($(this).is('[data-sort="most_views"]')) {
    // do my operation

  }
});

If anyone has a solution or can offer assistance with this issue, it would be greatly appreciated.

Answer №1

Avoid the default action of a link by using this simple jQuery code:

$('a[data-sort]').click(function(e) {
  e.preventDefault()
  ...

When using the .click function, you can prevent the default behavior and handle the event accordingly: https://api.jquery.com/event.preventdefault/

Answer №2

In the event that you prefer not to proceed with navigating to your link, simply use the command return false;

This action will alter the default behavior of the browser and prevent your page from being refreshed.

$('a[data-sort]').click(function() {
     console.log("CLICK DAT SORT");
     if ($(this).is('[data-sort="most_views"]')) {
         // do my operation

         }

         return false;
});
