IE Object required error and other common coding mistakes

Been having a lot of work on customizing Dokeos for a client, so didn’t really have any spare time to write.

Simulating mouse clicks in JavaScript
Filed Under JavaScript, Programming | 7 Comments
There might 
be times when you would like to simulate a mouse click on an DOM Node and don’t know how (for instance, submitting a form when in multi-frame environment).
Furthermore, it would be nice if the functionality could extend the DOM, so as to be able to use it combined with other pre-existing features.
Here’s the script bellow, just added and use it as you please (Ex. document.getElementById(”my_element”).click();)
HTMLElement.prototype.click = function() {
var evt = this.ownerDocument.createEvent('MouseEvents');
evt.initMouseEvent('click', true, true, this.ownerDocument.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);
this.dispatchEvent(evt);
}
