javascript - Submit form after event.preventDefault? -

i know question has been asked million times cant seem make work. can let me know i'm doing wrong.

here's code:

$('#frm').submit(function(event) {     event.preventdefault();     var formdata = $(this).serialize();     var email = $('input#email').val();     if (email == '') {         alert('please enter email address');         $('input#email').focus();         return false;     } else {         $.post('http://www.domain.com/', formdata, function() {             $('#frm').submit();         });     } }); 

you can submit form using dom node submit method:

$.post('http://www.domain.com/', formdata, function() {     this.submit(); // 'this' not '$(this)' }.bind(this)); // 'bind' set relevant context, or use jq $.proxy(handler, this) support older browsers
