关于 Touchjs 手势识别事件库 this 关键字与选择器不对称情况

Touchjs 版本 v0.2.14

废话不多，直接看代码，一个拖动实例

<div id="touch-drag"></div><script type="text/javascript">var dx, dy;touch.on('#touch-drag', 'drag', function(ev){  dx = dx || 0;  dy = dy || 0;  var offx = dx + ev.x + "px";  var offy = dy + ev.y + "px";  this.style.webkitTransform = "translate3d(" + offx + "," + offy + ",0)";  console.log(this); //-> <div id="touch-drag"></div>});touch.on('#target', 'dragend', function(ev){  dx += ev.x;  dy += ev.y;});</script>
