submit with enter textbox

[Opan Mustopah]

hello again,

i have a problem with submitting form by enter key. the form not using form plugins. but only input element using textbox plugins.
when i have done fill the username and password input, and then i press enter key, but value in password input not sent to server, if i lost focus on password input and then focused it again in password input, it works.

here is my code :

Code:

$('#btn_login').click(function(){
		$('#form_login').submit();
	});

	$('#form_login').keydown(function(e){
		if (e.keyCode == 13){
			$('#btn_login').trigger("click");
		}
	});

so why it happen?

thanks
