submit form does not stop in jquery ajax call

Question

I got following code :

$.ajax({
    type: \"POST\",
    async: false,              
    url: \"CheckIdExist\",
    data: param,
    success: function(result)         


        

Answer 1

You can't put this code in a function or in the onsubmit of a form, the success function returns it's result returning to the jQuery ajax context, NOT the form submit context.
