Question

The .load() function of the jQuery library allows you to selectively load elements from another page (subject to certain rules). I would like to know whether it is possible to abort the load process.

In our application, a user can browse a list of items. They may choose to click a button which loads and displays additional information about an item from another document (which can take some time). If they choose a different item in the list whilst a .load() is still happening, I would like the loading to be aborted.

Is this possible? Is it even worth it? Any ideas?

You can’t do this with .load() directly, since it returns the jQuery object for chaining, but if you change to the full $.ajax() call with .html() you can, like this:

var xhr = $.ajax({
            url: 'mypage.htm',
            success: function(data) {
              $("#myElement").html(data);
            }
          });
//if needed, abort the request later..
xhr.abort();

This uses the .abort() method on the XMLHttpRequest object to abort the load.
