Submitting form using enter key

Submitting form using enter key

Hi Dear JQuery programmers,

Good Day !
I am trying to use an image based hyperlink button for submitting form. So i am able to click on the image and submit form.
Now requirement is to submit form if enter key is pressed in page. I copied some code from net but unable to work.
Below is my code. Please correct me if i am going wrong somewhere.
Thanks in Advance !

<script type="text/javascript">
$('#myform').keypress(function(event) {
    if (event.which == 13) {
        $('#myform').submit();
    }
});
