(By the way, a quick experiment indicates that the answer is "yes", but it might be "it doesn't work in every browser".)

I am using a validator plugin that binds something to the submit event of a form. But I want to perform additional validation. It would seem that I can simply bind my additional validation to the submit event. 

HOWEVER, I worry that that might not work on every browser. Should I expect this to work or will I need to write more complex code?
