JQuery寫法：
$('#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;
}
原生寫法：
document.getElementById(

console.log(
"start"
,_x)
})

,
function
(e)
{
var
