How to redirect user to another page after Ajax form submission?

Question

I'm having problems redirecting the user to a thank you page after a successful form completion. What happens is that after the form submits, it goes to a blank page (https://cunet.sparkroom.com/Sparkroom/postLead)... I need it to redirect to a thank you page while submitting the form details to the URL in the 'form action'.

HTML Code:

<form action="https://cunet.sparkroom.com/Sparkroom/postLead/" method="post" name="theForm" 
id="theForm" onSubmit="return MM_validateForm();" >
...
</form>

Ajax Code:

<script src="http://malsup.github.com/jquery.form.js"></script> 
<script> 
    $('#theForm').ajaxForm(function() { 
    window.location.href = "I want the user to be redirected to this page";
});
</script> 

JavaScript:

function MM_validateForm() {
if ( !jQuery('#theForm #FirstName').val() ) {
alert('Please input your first name.');
jQuery('#theForm #FirstName').focus();
return false;
}
if ( !jQuery('#theForm #LastName').val() ) {
alert('Please input your last name.');
jQuery('#theForm #LastName').focus();
return false;
}
if ( !jQuery('#theForm #daytimephone').val() ) {
alert('Please input your phone number.');
jQuery('#theForm #daytimephone').focus();
return false;
}
if ( !jQuery('#theForm #Email').val() ) {
alert('Please input your email.');
jQuery('#theForm #Email').focus();
return false;
}
if ( !jQuery('#theForm #BID').val() ) {
alert('Please select your preferred campus.');
jQuery('#theForm #BID').focus();
return false;
}
if ( !jQuery('#theForm #programs').val() ) {
alert('Please select your preferred program.');
jQuery('#theForm #programs').focus();
return false;
}
if ( !jQuery('#theForm #How_Heard').val() ) {
alert('Please select how you heard about us.');
jQuery('#theForm #How_Heard').focus();
return false;
}
return true;
}
// ]]></script>

Does anyone know what I'm doing wrong? I need the form to submit the data to the URL and then after redirect the user to a 'thank you' page, right now that is not at all happening.

Try

window.location.href = "http://www.msdn.com";
