touchmove Event not firing on iPhone Safari

Does the touchmove event NOT work on the iPhone's Safari browser?
I'm not talking about an iOS App, just a regular old HTML page with some Javascript and jQuery that's loaded into the iPhone's Safari Browser.
I actually connected my iPhone to my Mac-mini - which is also running Safari, so I can see everything that's happening on the iPhone in the Mac-Mini's Safari console - and my touchstart and touchend events DO fire, but touchmove just does NOT respond.
Here's the code:
document.addEventListener("touchstart", onMobileTouchStart, false);
document.addEventListener("touchmove", onMobileTouchMove, false);
document.addEventListener("touchend", onMobileTouchEnd, false);
function onMobileTouchStart(touchStartEvent) {
console.log("\n==>'onMobileTouchStart'!!!");
touchStartEvent.preventDefault();
}
function onMobileTouchMove(moveEvent) {
console.log("\n==>onMobileTouchMOVE'!!!");
moveEvent.preventDefault();
}
function onMobileTouchEnd(touchEndEvent) {
console.log("\n==>onMobileTouchEnd'!!!");
}
What I'm ultimately trying to do is get a custom pinch-zoom type behavior going, and my understanding is that this has to be implemented in the touchmove event - so that's why I'm asking.
I can't see any other way of tackling this unless touchmove starts playing nicely.
Any thoughts, tips or workarounds for this?

I see the same problem in May 2021. I get the touchmove events just fine if i try it on Google Chrome, but Safari, on 14.4.2 (latest version), the Safari browser gives me the initial touchdown event, but subsequent touchmove events are not being fed to me.
Clearly the browser is stealing the touchmove event, because it wants to scroll something, and as usual scrolling is fouling up everything, because it is one of these things that HTML / JS spec doesn't really cover, as it is magical browser behavior.
I have a overflow:hidden on my body tag, so there shouldn't be any scrolling anyway. Not sure how to fix this browser quirk, since the iPad is a massively popular device, i must figure out how to fix it, but i am baffled at the moment.

Why are select events not firing in iOS?

I have built a website that uses some simple JavaScript. I make use of many events throughout the website such as the input and submit event for validating and processing a contact form, the focus event for some form-related things and a dynamically-created tab interface, etc. I register all of these handlers using element.addEventListener("event", handler).
My JavaScript works wonderfully everywhere that I have been able to test (Firefox and Chrome on Ubuntu; Firefox and Chrome on Android), except for on iOS devices (regardless of what browser is used), where it seems that very few events are being fired.
It has been difficult for me to debug what the issue is on iOS devices because I do not have an OSX computer to connect an iOS device to so that I can use the remote console. I have come to the conclusion that the events are not firing for a few reasons:
The contact form on the website is being submitted even though I make a call to event.preventDefault() in the form's submit event handler, and do not explicitly submit the form anywhere after that.
I have tried catching any errors and displaying them in an alert like so:
window.onerror(function(err) { alert(err) })
to no avail (i.e. no errors were caught).
I have adapted all my functions to make use of only the click event, and then they work perfectly!
The last point is a possible solution to the problem, but I think it is bad practice to adapt all my work to one specific platform and rely only on a single event when there are so many purpose-built events that can be used and that are supposedly supported by iOS in the first place.
Why are so many events not being fired on iOS devices?

The problem was actually that I had made a const declaration in strict mode, which is, according to caniuse, not recognized in the current versions of both Safari and iOS Safari (9.1 and 9.3, respectively, as of writing).
I have better documented this problem in another question and answer.

Do the touch events touchleave and touchenter exist?

I've tried a couple different devices and I have never been able to see a touchleave or touchenter event. I've tried:
chrome, enabling touch event emulation
chrome and firefox using phantom limb
Android galaxy s2 via cordova
So what gives? Why does mozilla list these things in their reference? While we're on the subject, what kinds of things trigger touchcancel? I've never seen that event either.

I think they exist but they don't do anything.

I have tried touchleave and touchenter, but both do nothing. No callback will come to there methods. I think Developers have defined these methods but forgot to implement them..

How do I detect when the address bar of mobile Safari hides on GWT?

GWT 2.5.1 /
MGWT 1.1.2
I added a resize handler to the Window, however no resize event is triggered when the address bar hides in mobile safari (tested on iOS 6x), The event is properly thrown if the handler is added natively with Javascript.
I'm not sure what event to expect when that happens. I don't want to rely on solutions that require setTimeOut's, native code or any other battery consuming workarounds.
Any ideas?
EDIT:
This behavior seems to be a bug on MGWT code. I already issued a report:

Windows touch events in web page

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.
