How to get the sliding distance length in touch event
This time I bring you touchEventHow to get the sliding distance length, touch event to get the sliding distance lengthWhat are the precautions, the following is a practical case, let's take a look .
Calculate the distance of gesture sliding when gesture slides on the mobile phone screen. The code is as follows:
function wetherScroll(){ var startX = startY = endX =endY =0; var body=document.getElementsByTagName("body"); body.bind('touchstart',function(event){ var touch = event.targetTouches[0]; //滑动起点的坐标 startX = touch.pageX; startY = touch.pageY; // console.log("startX:"+startX+","+"startY:"+startY); }); body.bind("touchmove",function(event){ var touch = event.targetTouches[0]; //手势滑动时,手势坐标不断变化,取最后一点的坐标为最终的终点坐标 endX = touch.pageX; endY = touch.pageY; // console.log("endX:"+endX+","+"endY:"+endY); }) body.bind("touchend",function(event){ var distanceX=endX-startX, distanceY=endY - startY; // console.log("distanceX:"+distanceX+","+"distanceY:"+distanceY); //移动端设备的屏幕宽度 var clientHeight; =document.documentElement.clientHeight; // console.log(clientHeight;*0.2); //判断是否滑动了,而不是屏幕上单击了 if(startY!=Math.abs(distanceY)){ //在滑动的距离超过屏幕高度的20%时,做某种操作 if(Math.abs(distanceY)>clientHeight*0.2){ //向下滑实行函数someAction1,向上滑实行函数someAction2 distanceY <0 ? someAction1():someAction2(); } } startX = startY = endX =endY =0; }) }
