由于移动端是触摸事件，所以要用到H5的属性touchstart/touchmove/touched,但是PC端只支持鼠标事件，所以此时可以这样转换var touchEvents = {        touchstart:"touchstart",        touchmove:"touchmove",        touchend:"touchend",        initTouchEvents:function () {
  　　　　　　　var self = this;            if (self.isPC()) {                self.touchstart = "mousedown";                self.touchmove = "mousemove";                self.touchend = "mouseup";            }        }, 　　　　 isPC:function(){  //判断pc端与移动端

var userAgentInfo = navigator.userAgent;             var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  //判断用户代理头信息           var flag = true;             for (var v = 0; v < Agents.length; v++) {                 if (userAgentInfo.indexOf(Agents[v]) != -1) { flag = false; break; }             }             return flag;   //true为pc端，false为非pc端

　　　　 }    };
