This snippet maps mouse events and touch events onto one single event. This makes it easier in the code since you have to listen to only one event regardles whether it's desktop or mobile.
(function() {
TouchMouseEvent = {
DOWN: "touchmousedown",
UP: "touchmouseup",
MOVE: "touchmousemove"
var onMouseEvent = function(event) {
var type;
switch (event.type) {
case "mousedown": type = TouchMouseEvent.DOWN; break;
case "mouseup": type = TouchMouseEvent.UP; break;
case "mousemove": type = TouchMouseEvent.MOVE; break;
var touchMouseEvent = normalizeEvent(type, event, event.pageX, event.pageY);
var onTouchEvent = function(event) {
var type;
switch (event.type) {
case "touchstart": type = TouchMouseEvent.DOWN; break;
case "touchend": type = TouchMouseEvent.UP; break;
case "touchmove": type = TouchMouseEvent.MOVE; break;
var touch = event.originalEvent.touches[0];
var touchMouseEvent;
if (type == TouchMouseEvent.UP)
touchMouseEvent = normalizeEvent(type, event, null, null);
touchMouseEvent = normalizeEvent(type, event, touch.pageX, touch.pageY);
/* == NORMALIZE == */
var normalizeEvent = function(type, original, x, y) {
return $.Event(type, {
pageX: x,
pageY: y,
originalEvent: original
var jQueryDocument = $(document);
if ("ontouchstart" in window) {
jQueryDocument.on("touchstart", onTouchEvent);
jQueryDocument.on("touchmove", onTouchEvent);
jQueryDocument.on("touchend", onTouchEvent);
} else {
jQueryDocument.on("mousedown", onMouseEvent);
jQueryDocument.on("mouseup", onMouseEvent);
jQueryDocument.on("mousemove", onMouseEvent);

You can simply do $(document).on('touchstart mousedown', doSomething); or if not using jQuery I have an abstraction for touch events as well, only thing I plan to change is to remove momentum from the ended dispatch (since it's easy to calculate and most times not needed):

nice - thanks for the review. That would make the sure would make the code less verbose. I pretty much only use this snippet when I need X/Y coordinates. I'd say the nicest part is not the "one event for all" - thing but rather the easy access for X and Y. One thing I might add is X/Y on touchend. It's really annoying that webkit does not support it. In my mind, that makes absolutly no sense.

Anyways. I have to rework this code anyways. Just made it a gist for easy access for an article I wrote. I didn't want to make a repo for 70 lines of code. :)

Thanks for feedback.

This is a great piece of code. It works well, but I cannot seem to be able to make it work with the .live() function. I made sure that the TouchMouseEvent was fired, but for some reason the code in the live() function does not execute. I tried :
$('#MyElement').live('TouchMouseEvent', function(){...});
$('#MyElement').live('normalizeEvent', function(){...});
$('#MyElement').live('touchMouseEvent', function(){...});

None of them worked. I know that since jQuery 1.4, the live() function supports custom events, so I don't know why this would not work.
Any help would be appreciated.

@alexlaq Hey, I'm sorry - I haven't seen your comment until now (7 months later ... I know). You problably have figured it out by now but anyways:

You have to listen to one of the TouchMouseEvent like so:

$( "#id" ).live( TouchMouseEvent.DOWN, function( event ) {...} );


$( "#id" ).live( "touchmousedown", function( event ) {...} );

I hope that helps.

Thanks a lot Mathias for this amazing snippet, it's working very nice with my image crop process, because of this I have mobile devices enabled. :)

Hi, i have an html file with with mouse events in it, i linked your js file to it and tried on cordova.. but no success. can u please help me.. Thank you.

You just save the day, the script works perfectly and avoid to us have to write down a different script when user enter vía touch device.

Thanks for this, I was going crazy trying to normalize. Touchend events can be handled, (at least in iOS Safari 7+, haven't tested everywhere), like so:

if (type == TouchMouseEvent.UP) {
    var touch = event.originalEvent.changedTouches[0];
    touchMouseEvent = normalizeEvent(type, event, touch.pageX, touch.pageY);

One minor caveat of your approach is that it doesn't allow calling event.preventDefault(); you must call event.originalEvent.preventDefault() after normalizing. Just a heads-up.

Thanks for this! This is a life saver! I got a problem in iOS 7.1 Safari browser that when you generate a draggable element via javascript, the browser detect it as a mouse event. So you can't really drag the element.

How would I deal with things like targetTouches or the equivalent of that for mouse events?

Adding this piece, in the "onMouseEvent" listener, will remove right click:

if (event.which === 3) { return; }
