html5 touch event

The recent app project I was working on caused a lot of problems due to the use of overflow: hidden, so I decided to study the touch event of HTML5. It is difficult to find a comprehensive post.

A relatively comprehensive small demo of sliding up and down, the code is relatively simple.

The following is the complete code. I have marked several important places in red

function touchEnd(e){//Finger leaves the screen
e.preventDefault();
aboveY=parseInt(inner.style.top);//Record the internal slider after the touch is completed The sliding position is reflected in the global variable and must be converted into an integer using parseInt();
