如何在jquery中阻止表单提交行为？

Question

I need to get an .click() event and prevent form from behaving as it was initially designed and make my own changes and submit. How is it possible?

EDIT: Form input actually has an onclick defined behavior. I need to redefine it somehow.

EDIT: Some code

<form action='link' method='get'>
   <input type="image" name="name" id="id" class="class" onclick="this.form.action='some_link'" title="Title" value="" src="image.gif">
</form>

Answer 1

If you don't want it to submit the form, return false at the end of your click function. If you want to submit the form, use the form element and call the submit function on it:

$('#myFormID').submit();

Answer 2

$('#form').submit(function(e) {
    // Some code
});

I think it's enough.

Answer 3

You could use something like this (haven't tested it but it should work)

form = $("#yourform");
button = $("#yoursubmit");
button.click(function(){
             dosomething();
             form.submit();
             return false;});
