I'm trying to figure out how to add event listeners for windows touch events (like a big touch screen monitor, not mobile) in Windows 7 and can't seem to make things like touchstart touchend etc. trigger in any browser. Do these events just not fire in a browser like they do on an iPad?
As far as I know, those events are included only in some mobile navigators (not all, see http://www.quirksmode.org/mobile/tableTouch.html ). I don't think you can handle them on a standard browser like ff/ie/chrome. You'll have to use mousedown & cie.
Take a look at the v2 branch of hammer.js http://eightmedia.github.com/hammer.js/v2/, it's a nice touch event abstraction layer for iOS, Android, BlackBerry and also includes support for Windows touch events.

my application is using the Touch API to detect touch events in JavaScript. Example:
$(".element").on("touchstart", function(event){
alert("TRUE");
});
This works on any touch device with any browser like Android or iOS, however it doesn't work in MS Edge on a Windows 10 Tablet with or without conntected keyboard. The API seems to be supported: Compatibility list. However, I've tested: 'ontouchstart' in window and this returns false on this device. Furthermore mousedown seems to get fired.
What is going on here? What can I do to fire touch events on a Windows 10 tablet?
I would like to keep the event only for touch devices. Switching to the Pointer Events API would include also Desktop devices and that is not what I want.
for touch API, you have to activate a flag on Edge : in the address bar, enter about:flags and press enter. In the section Touch, you can enable touch events with the corresponding dropdown
Did you enable custom touch handling ? You can do it with the following css snippet (on the body tag or just a container for geastures) :
-ms-touch-action: none;
Next, touch API is a webkit feature (maybe there is an error in CanIuse ?). IE and Edge have a similar feature known as Pointer API. But you can use a polyfill library like this :
https://github.com/CamHenlin/TouchPolyfill
Try using the pointerdown event. Some (much) more information. As you can see, touchstart is triggered by Edge but not in all configurations, when a keyboard is attached/paired for example, no touchstart.
I'm using JQuery Mobile for recognizing swipe events and it works well. Events fire on Windows Mobile (7.5 in my case), but what also fires is the web browser's default events for navigating the browsing history. Swiping right turns back a page. How can I prevent this default behavior?
I tried the preventDefault() and it didn't help here.
It will deactivate the touch:-
Add CSS snippets:
*{
touch-action: none;
}
But to reactivate the touch event only on the some zone, to allow the player to play or active the touch
To activate for certain places add this :-
#activetouch{
touch-action: chained;
}

Windows Phone 7/IE9 does not support mousemove event so there is not way for jquery mobile to recognize swipe event.
Some mobile frameworks like Apache Cordova (PhoneGap) provide workaround for this by adding special shim between native (silverlight) touch events and web browser control to fix missing mouse events. Demo
This works fine on Windows Phone 8 since it supports mousemove.
I'm building an app in phonegap. The app makes heavy use of javascript and has a content area that should be scrollable. However I also need to use the touchStart and touchEnd events.
The problem is that, unless you use e.preventDefault on touchMove/touchStart, you will get the touchStart event only once and never again after that (Not useful).
If you do e.preventDefault() on either of those two, native scrolling is disabled (on mobile devices).
How do I allow native scrolling while also listening to touchstart + touchend?
Failing that, could I simulate native scrolling (using touchmove?)? I've tried my hand at this myself, and the result of that was frankly terrible.
I'm developing a jquery component which works primarily for ipad. So is there anyway to simulate 'touchstart and 'touchend' events in desktop rather than having the device itself to check the events.
You can author your own custom events within jQuery:
var event = $.Event( "touchstart", { pageX:200, pageY:200 } );
And you can issue them against any element in the DOM:
$("body").trigger( event );

Keep in mind that there are various other types of interfaces on the market now that don't support touchstart and touchend events. For instance, Windows 8 is already occupying tablets in the mobile market, and it uses a more abstracted event model consisting of Pointers.
Chrome Dev-tools within a Chrome Browser allows you to emulate touch events. See https://developers.google.com/chrome-developer-tools/docs/mobile-emulation.
From the docs...
Emulating Touch Events
Touch is an input method that's difficult to test on the desktop,
since most desktops don't have touch input. Having to test on mobile
can lengthen your development cycle, since every change you make needs
to be pushed out to a server and then loaded on the device.
A solution to this problem is to simulate touch events on your
development machine. For single-touches, the Chrome DevTools supports
single touch event emulation to make it easier to debug mobile
applications on the desktop.
To use from a Chrome browser (as of version 29.0.1547.65):
Select the Chrome menu at the top-right of your browser window (three stacked lines).
Select Tools > Developer tools. (Shortcut Shift+Control+I)
A tools window will appear on the bottom with the tab Console selected.
In the bottom right click on the settings cog (look like a gear).
A setting panel will appear with "General" on top.
Click "Overrides" on left to select overrides panel.
Scroll down and check "Enable touch events"
Reload your page
You mouse will now appear as a fuzzy circle. Click to "touch".
As of 2018, Chrome DevTools supports device emulation outright, without any need for override setting. Just toggle the device toolbar (Ctrl + Shift + M) to get the browser into mobile mode, then touch events can be triggered by the mouse.
I am developing an HTML application for the iPad. As such it utilizes touch events and webkit-CSS animations.
Up until now I have used chrome as my debugging environment because of it's awesome developer mode.
What I would like is to be able to debug my Html/JavaScript using Google-Chrome's debugger on my PC while simulating touch events with my mouse.
My site does not have any multi-touch events and no mouse events (no mouse on iPad).
I am not actually interested in seeing the applications layout, but more in debugging its behavior.
Is there some plugin to get mouse events translated into touch events on a desktop browser?
As of April 13th 2012
In Google Chrome developer and canary builds there is now a checkbox for "Emulate touch events"
You can find it by opening the F12 developer tools and clicking on the gear at the bottom right of the screen.
For now (Chrome ver.36.0.1985.125) you can find it here: F12 => Esc => Emulation.
The desktop browser can simulate touch events by importing additional JS + CSS.
Take a look at:
addTouch
Phantom Limb
Another way to simulate multi touch on a desktop browser is the Touch Emulator of Hammer.js
We use this script: http://code.google.com/p/jquery-ui-for-ipad-and-iphone/
It will allow all mouse events in your application to be triggered by touch events instead. So, since we already had a web application that used right-clicking, drag-n-drop etc. it allowed us to perform all of the same functionality with touch.
I know it's almost the reverse of the simulation you were looking for (you will have to script your application to primarily be used by a mouse) but I hope it helps anyway.
If you're targeting Webkit specifically (iPad and all), you can rely on normal event handler code (add/removeEventListener). With that in mind, you probably need to just branch on a few events - e.g, 'ontouchstart' becomes 'onclick' based on the environment.
Offhand I don't know of any libraries providing this level of branching, though. Pretty easy to do yourself.
