What is the easiet way to use jQuery Form Plugin?

What is the difference between ajaxForm and ajaxSubmit?

There are two main differences between these methods:

1. ajaxSubmit submits the form, ajaxForm does not. When you invoke ajaxSubmit it immediately serializes the form data and sends it to the server. When you invoke ajaxForm it adds the necessary event listeners to the form so that it can detect when the form is submitted by the user. When this occurs ajaxSubmit is called for you.
2. When using ajaxForm the submitted data will include the name and value of the submitting element (or its click coordinates if the submitting element is an image).

How can I cancel a form submit?

You can prevent a form from being submitted by adding a ‘beforeSubmit’ callback function and returning false from that function. See the Code Samples page for an example.
