Code:
$("loginForm").submit(function () {
That's not a good selector, I think. It should probably look something like:
Code:
$("form [name='loginForm']").submit(function () {
That's for problem #2. However, if it's correct, then the submit handler should have never fired on form submission. That means the backside should never have been called in the first place and no data would have been passed.
Try the selector change and see what happens.
