问题
I'm really struggling on an Android app in Phonegap and JQuery.
All I want to do is bind a touchmove to an element and then check the X and Y coordinates as I move my finger (a drag, basically)
$('#someElm').bind('touchmove',function(event){
//Code here..!
});
The touchmove fires when I touch the screen, but then I don't really know what the objects of the event are - I've tried event.screenX, event.pageX, but the don't work.
Any ideas?

Here the reference for mobile safari (android is basically the same):
https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html
what you want is:
var x = event.touches[0].pageX;
var y = event.touches[0].pageY;
If you are running on android you also need to cancel the touchmove event to get new ones while touching. Don't ask me why...
