jQuery写法

$('#id').on('touchstart',function(e) {
    var _touch = e.originalEvent.targetTouches[0]; 
    var _x= _touch.pageX;
});

$('#id').on('touchmove',function(e) {
    var _touch = e.originalEvent.targetTouches[0]; 
    var _x= _touch.pageX;
});

$('#id').on('touchend',function(e) {
    var _touch = e.originalEvent.changedTouches[0]; 
    var _x= _touch.pageX;
}）;

原生写法

document.getElementById("id").addEventListener("touchstart",function(e) {
    var _x=e.touches[0].pageX;
    var _y=e.touches[0].pageY;
    console.log("start",_x)
});

document.getElementById("id").addEventListener("touchmove",function(e){
    var _x=e.touches[0].pageX;
    var _y=e.touches[0].pageY;
    console.log("move",_x)
});

document.getElementById("id").addEventListener("touchend",function(e){
    var _x=e.changedTouches[0].pageX;
    var _y=e.changedTouches[0].pageY;
    console.log("end",_x)
});
