javascript - jQuery event.preventDefault() not working in Firefox (JSFiddle included)

Question

This is a kind of similar duplicate to some others here, but I think I'm using event.preventDefault() correctly in this case.

Here's a JSFiddle you can see the code with: http://jsfiddle.net/SeEw2/2/

Basically, click the Submit button.

In Chrome: Nothing happens - correct response.

In Firefox: Page reloads, oh noes!

So why is the page reloading in Firefox and not Chrome? I've been Firebugging it and no errors come up in either...

Answer 1

The variable event in your code is not initialized.

extract :

 $('#ajaxsearch').click(function(event) {

        // Stop the Search input reloading the page by preventing its default action
        event.preventDefault();
