Mobile side when the popup layer appears, prevents the body from sliding

Many times the front-end in the mobile side of the pop-up layer when the slide screen, body or can slide, these times to stop, words do not say, directly look at the code

First define a variable, I define the Stop=1, when the pop-up layer shows, stop=0, and then listen to touchmove events, prevent bubbling and default behavior, so that the effect is achieved.

Document.addeventlistener ("Touchmove", function (e) {
if (stop = = 0) {
E.preventdefault ();
E.stoppropagation ();
}
}, False);
