Answer 1

Jaspers solution above worked for me! The only thing I had to adjust was replacing .live with .submit (.live is now deprecated). So now its like this:

$('#form_id').submit(function (e) {

    //cache the form element for use in this function
    var $this = $(this);

    //prevent the default submission of the form
    e.preventDefault();

    //run an AJAX post request to your server-side script, $this.serialize() is the data from your form being added to the request
    $.post($this.attr('action'), $this.serialize(), function (responseData) {

        //in here you can analyze the output from your server-side script (responseData) and validate the user's login without leaving the page
    });
});

If you want to submit a form and not use ajax (which is default) you must add 'data-ajax="false"' to your form string:

 <form data-ajax="false" action="test.php" method="POST">

Answer 3

If you handle form submission with a custom submit event handler you can handle validation on the same page:

//bind an event handler to the submit event for your login form
$(document).on('submit', '#form_id', function (e) {

    //cache the form element for use in this function
    var $this = $(this);

    //prevent the default submission of the form
    e.preventDefault();

    //run an AJAX post request to your server-side script, $this.serialize() is the data from your form being added to the request
    $.post($this.attr('action'), $this.serialize(), function (responseData) {

        //in here you can analyze the output from your server-side script (responseData) and validate the user's login without leaving the page
    });
});

To stop jQuery Mobile from running its own AJAX sumbission of your form put this on your form tag:

<form data-ajax="false" action="...">
