HTML5 touch event realizes sliding up and down of touch screen page
This article mainly introduces in detail the code related to the html5 touch event to realize the up and down sliding of the touch screen page. The code comments are very clear. Interested friends can refer to what
has done recently. The app project caused many 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. Although there are many articles about html5 touch, most of them introduce touch events or very short demos.
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
