You can dispatch a click event in the following way:

	var clickElement = document.getElementById('someId);

	var evt = document.createEvent("MouseEvents");
	evt.initMouseEvent("click", true, true, window,	
			0, 0, 0, 0, 0, false, false, false, false, 0, null);

	clickElement.dispatchEvent(evt);

HTH!
