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

document.onkeypress = function (e) {
 e = e || window.event;
 var charCode = (typeof e.which == "number") ? e.which : e.keyCode;
 if (charCode == 13) {

        // Do something here
        printResult();
    }
};

Heres my two cents. I am working on an app for Windows 8 and want the button to register a click event when I press the Enter button. I am doing this in JS. I tried a couple of suggestions, but had issues. This works just fine.
