Do the touch events touchleave and touchenter exist?

Question

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.

Answer 1

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..

Answer 2

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