My goal is: When for is submitted:
You can call the native submit event, so do this:
$('#form1').submit(form1Submit);
Then in your post callback do this:
$.post("check.php", { username: username, password:password }, function(data) {
if (data=="ko") {
alert('bad password');
} else {
this.submit();
}
});
The this.submit() isn't calling he jQuery .submit() trigger function, but rather the native .submit() function.
