Jquery to javascript keypress event

Question

I have the following in jquery code:

$(document).keypress(function (e) {
    if (e.keyCode == 13) {

    }
});

How can I make this into javascript so I do not need to load jquery everyime?

Answer 1

document.onkeypress = function (e) {
    if (!e) var e = window.event;
    var keyCode = e.keyCode || e.which;
    if(keyCode == 13) {

    }
    ...
}
