Answer 1

event.initMouseEvent("click"...

Here is an example:

function simulateClick(elId) {     var evt;     var el = document.getElementById(elId);     if (document.createEvent) {         evt = document.createEvent("MouseEvents");         evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);     }     (evt) ? el.dispatchEvent(evt) : (el.click && el.click()); }  var foo = document.getElementById("hey");  foo.onclick = function () {alert("bar");}  simulateClick("hey");
