If you want to check if the form data, as it is going to be sent to the server, have changed, you can serialize the form data on page load and compare it to the current form data:

$(function() {

    var form_original_data = $("#myform").serialize(); 

    $("#mybutton").click(function() {
        if ($("#myform").serialize() != form_original_data) {
            // Something changed
        }
    });

});
