移动端与PC端的触屏事件

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

　　　　 }
    };
