[jQuery] jQuery.post -> PHP script -> redirect


Hi All,
I have following problem:
I would like to post (jQuery.post) login-form variables to the PHP
script ("backend.php") for validation and if it is succesfull then
redirect to "myaccount.php".
Here is my code:
<script type="text/javascript">
$(document).ready(function() {
    $("#submit_butt").click( function() {
        // configurations for the buzzing effect. Be careful not to make it
too annoying!
        var conf = {
                frequency: 5000,
                spread: 5,
                duration: 600
            };
        /* do your AJAX call and processing here...
            .... */
            var unameval = $("#username").val();
         var pwdval = $("#pwd").val();
         //alert(unameval+pwordval);
         $.post("backend.php", { username: unameval, pwd: pwdval }, function
(data){
if(data.length >0) {
window.location.href("account.php");
}
});
        // this is the call we make when the AJAX callback function
indicates a login failure
        $("#login").vibrate(conf);
        // let's also display a notification
        if($("#errormsg").text() == "")
            $("#loginform").append('<p id="errormsg">Nesprávne meno alebo heslo!
');
        // clear the fields to discourage brute forcing :)
        $("#username").val("");
        $("#pwd").val("");
    });
});
</script>
Can you help me? Any suggestions???
Thank you very much for your response....
Best,
Marian
