Subject: [jQuery] on form submission, how to decide "on submit: return true
/ false"
Hi there,
I got helps and also debugging on self for days on trying to implement
a form submission with jQuery,
now I was stunk on getting the results from call back .Post or .ajax
to pass true & false to the form submission.
the code is pretty simple here:
$(document).ready(function()
{
$("#regForm").submit(function()
{
$.post("check.php", { username: $('#username').val(),password: $
('#password').val() }, function(data)
{
$('#errorMessage').html(data);
if (data == "pass" ) return true; else return false;
//check.php will output { "pass", "user name
already token", "input username & password"}
//problem here, the true / false value doesn't
work.
//even if I commented this line and add return
false, the form will still be submitted.
//I got kind suggestions should try replace $.Post
with $.ajax to call here, but don't know how to.
});
});
});
the full code:

});
});
