Trigger a keypress/keydown/keyup event in JS/jQuery?

Question

What is the best way to simulate a user entering text in a text input box in JS and/or jQuery?

I don\'t want to actually put text in the input box,

Here's a vanilla js example to trigger any event:

function triggerEvent(el, type){
if ('createEvent' in document) {
        // modern browsers, IE9+
        var e = document.createEvent('HTMLEvents');
        e.initEvent(type, false, true);
        el.dispatchEvent(e);
    } else {
        // IE 8
        var e = document.createEventObject();
        e.eventType = type;
        el.fireEvent('on'+e.eventType, e);
    }
}
