jQuery event.preventDefault() not working in Firefox (JSFiddle included)
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... The variable event in your code is not initialized. http://jsfiddle.net/SeEw2/4/ extract : $('#ajaxsearch').click(function(event) { // Stop the Search input
