About jquery unblock default events

Recently help a friend to do something, the whole screen has a mask layer, but this mask layer can slide, so Baidu a bit, return to the present, with

$ (' body '). Bind ("Touchmove", function (e) {
E.preventdefault ();

});

This sentence, you can stop the mask layer sliding, so that the screen fixed, but when the mask layer disappears, this screen still cannot slide, this is squid above that function is still executing, at that time, has been in Baidu a method, is how to unblock the default behavior, how also did not Baidu out, later drank saliva, brainwave, found that as long as the event just bound to release the good, so that the E.preventdefault () will not work, and then solve their own problems, this feeling is very good!
