Mouse Event

Published in: JavaScript 

Support: Fx2, Opera9, IE6 Remodeled "Event.observe" of prototype.js... is necessary for this. This is indispensable for MouseWheel to support.

Plain TextExpand 
  1. /*-----------------------------------------------------------------------------
  2.  * Mouse Event
  3.  *  Example Source
  4. 	Event.Mouse.right(window, function (e) {
  5. 		alert(Event.pointerX(e) + ', ' + Event.pointerY(e));
  6. 	});
  7. 	Event.Mouse.wheel(window, function (e, roll) {
  8. 		alert(roll);
  9. 	});
  10.  *  Event Observer Sample
  11. 	Event.observe = function (element, name, observer, useCapture) {
  12. 		useCapture = useCapture || false;
  13. 		// Start Remodel
  14. 		name = (name == 'keypress' && (navigator.appVersion.match(/Konqueror|Safari|KHTML/) || window.attachEvent)) ? 'keydown' : (name == 'mousewheel' && !window.attachEvent) ? 'DOMMouseScroll' : name;
  15. 		// End Remodel
  16. 		if (element.addEventListener)
  17. 			element.addEventListener(name, observer, useCapture);
  18. 		else if (element.attachEvent)
  19. 			element.attachEvent('on' + name, observer);
  20. 	}

  23. var Mouse = {
  24. 	left: function (element, func) {
  25. 		Event.observe(element, 'click', func);

  32. 			func.apply(this, [e]);
  33. 			return false;
  34. 		})
  35. 	},
  36. 	wheel: function (element, func) {
  37. 		Event.observe(element, 'mousewheel', function (e) {
  38. 			func.apply(this, [e, (e.wheelDelta) ? e.wheelDelta / -120 : e.detail / 3]);
  39. 			Event.stop(e);
