I'm already using a number of plugins and don't want to add more overhead for something as simple as calling a method on a native javascript object.
I was looking over the documentation for $.ajax and found this: $.ajax() returns the XMLHttpRequest that it creates. http://docs.jquery.com/Ajax/jQuery.ajax This should make it easier to call abort without the need of an extra callback. var xhr = $.ajax({ /* ... */ }); $.('button.cancel').click(function(event) { if (null !== xhr) { xhr.abort(); xhr = null; } event.preventDefault(); }); -- Hector On Wed, Aug 26, 2009 at 9:16 AM, Cesar Sanz <the.email.tr...@gmail.com>wrote: > Why to re-invent the wheel? > > ----- Original Message ----- > *From:* Hector Virgen <djvir...@gmail.com> > *To:* jquery-en@googlegroups.com > *Sent:* Wednesday, August 26, 2009 9:43 AM > *Subject:* [jQuery] Re: How to cancel an AJAX request? > > Thanks, Rupak, but I was hoping to be able to accomplish this without a > plugin.
