移動端與PC端的觸屏事件

因爲移動端是觸摸事件,因此要用到H5的屬性touchstart/touchmove/touched,可是PC端只支持鼠標事件,因此此時能夠這樣轉換

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(){ //判斷pc端與移動端
           var userAgentInfo = navigator.userAgent;  
           var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  //判斷用戶代理頭信息
           var flag = true;  
           for (var v = 0; v < Agents.length; v++) {  
               if (userAgentInfo.indexOf(Agents[v]) != -1) { flag = false; break; }  
           }  
           return flag;   //true爲pc端,false爲非pc端
     }
    };
