The submit method in jQuery

Previously we used this construction:

$('form').on('submit', function(event) {
	event.preventDefault();
});

Instead, we can also directly use the submit method in jQuery, which binds a form handler or executes an event:

$('form').submit(function(event) {
	event.preventDefault();
});

In the following example, we have a simple form to which we will bind an event handler using the submit method, with a text field and a button - an input of type submit:

<p>jQuery</p>
<form action="/">
	<div>
		<input type="text">
		<input type="submit">
	</div>
</form>
<span></span>

Let's enter text into a text field, and when we click on a button, check this text. If we enter 'jQuery', then in the span we will show the text 'Good!', using the methods text and show, and if something else, then - 'Bad...':

$('form').submit(function(event) {
	event.preventDefault();
		if ($('input').first().val() === 'jQuery') {
			$('span').text('Good!').show();
			return;
		}
	$('span').text('Bad...').show();
});
