Prototype.

Question

I would like to know if there is any equivalent of the jquery mousemove function in the prototype.

Answer 1

I think this will lead you to where you want to be:

Event.observe(document, 'mousemove', callBackFunction); callbackFunction = function(event) { //do something } 

Answer 2

This answer is not prototypejs, but you can always use the DOM API directly to assign a handler.

 document.onmousemove = function() { // do something }; 

You will have good cross-browser support if you do not try to place the event on a window . So use document or some other element.

To remove the handler later, assign null .

 document.onmousemove = null;
