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.

http://jsfiddle.net/SeEw2/4/

extract :

 $('#ajaxsearch').click(function(event) {          // Stop the Search input reloading the page by preventing its default action         event.preventDefault(); 

Answer 2

Ah I've had a similar problem in that past. Rather than event.preventDefault() try passing the event to:

    function ie8SafePreventEvent(e){     if(e.preventDefault){ e.preventDefault()}     else{e.stop()};      e.returnValue = false;     e.stopPropagation();         } 

I know it says IE, but I've never had a problem with it since =]
