[jQuery] Disable submit button with Validation plugin

[Rich Sturim]

I need help with the Validation plugin.  I have a form with a required
field.  When the form is valid I want the form to submit and I also
want to disable the submit button. I have a function that does the
disabling, but I'm not sure how to call this function within the
"validate" method.

Here is my simple call the the validate method.

$(document).ready(function() {
    $("#myForm").validate()
});

and here is my disable function --

jQuery.fn.diableOnSubmit = function() {
    var input=this.find("input.submit")
    input.click(function () {
        $(this).attr("disabled", true);
        $(this).attr("value", "Submitting...");
        $(this).submit();
    });
};

How do I combine the two together?

-Cheers,
