Answer 3

You're working with .button() widget of jQuery Mobile. <button> is converted into a div to give it a new look by jQuery Mobile.

When doing any changes to <button> or <a>, you need to refresh that element to re-apply styles.

All you need to do is:

$(".selector").val('Processing ...').button("refresh");

By the time the AJAX callback runs, this as a keyword has lost its context. You need to assign it to a variable to retain the reference. Something like this:

$(document).ready(function () {
    $('#submit_btn').click(function (e) {
        e.preventDefault();
        var button = $(this);
        button.val('Processing ...');
        $.ajax({
            cache: false,
            type: "POST",
            dataType: "json",
            data: $('#form1').serialize(),
            url: "echo/json",
            complete: function (HttpRequest, textStatus) {
                button.val('Create');
            }
        });
        return false;
    });
});
