Trigger a button click with JavaScript on the Enter key in a text box

Question

I have one text input and one button (see below). How can I use JavaScript to trigger the button\'s click event when the Enter key is pressed ins

Answer 1

onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('btnSearch').click();}};"

This is just something I have from a somewhat recent project... I found it on the net, and I have no idea if there's a better way or not in plain old JavaScript.
