How to trigger a keydown event?

Question

How can I simulate pressing a specific key on the document?

Important: without jQuery

With jQuery:

var e = $.Event('keydown');
e.which = 65;
document.trigger(e);

But how can I do this without jquery ?

Answer 1

Use 'addEventListener' to capture this action

document.addEventListener('keydown',keydownfunction,false);

function keydownfunction(event){
// this function triggers on any keydown
}
