For submit() use loadvars or geturl?

Hi,

Which of the following methods is the better one to use for forms

Simple Sample codes


function onSubmit() {
	email = email.text;
	name = name.text;
	getURL('form.php','','POST');
}

or


function onSubmit() {
	var formVars:LoadVars = new LoadVars();
	formVars.email = email.text;
	formVars.name = name.text;
	formVars.send('form.php','','POST');
}

What’s your advice and why??
