H5上滑跳转页面的实现（代码实例）

movePage($('body'));   function movePage(dom) {       var startY, moveY, moveSpave;       dom.on("touchstart", function(e) {               startY = e.originalEvent.touches[0].pageY; return startY;        });        dom.on("touchmove", function(e) {              moveY = e.originalEvent.touches[0].pageY;              moveSpave = startY - moveY;              if (moveSpave > 15) {                   location.href = 'main.html';              /* 跳转到main.html */               }        });  }

     var strat,move,num; /*定义三个变量, 记录开始、结束距离顶部的距离*/     p_demo.addEventListener("touchstart", function (e){        /*触摸开始*/            console.log("触摸开始")            // console.log(e)            start = e.touches[0].pageY;            console.log(start)       /*得出刚触屏时距离页面顶部的距离*/      })     p_demo.addEventListener("touchmove", function (e){       /*触摸移动*/            console.log("触摸移动")            // console.log(e)            move = e.touches[0].pageY;            console.log(move)     /*得出触屏结束后距离页面顶部的距离*/    })    p_demo.addEventListener("touchend", function (e){            /*触摸结束*/            console.log("触摸结束")            // console.log(e)            num = start - move ;   /*得出开始和结束距离页面顶部的差值*/            if(num>15){                 location.href="main.html"           /* 跳转到main.html */            }    })
