Solution to overflow: Auto in mobile safari

This time, there was a project that needed full support for iPad, and many problems were encountered in the middle. Today there is a div that requires a scroll bar to expire under the safari of the iPad. mobile safari removes the scroll bar in the local area due to multi-touch (to prevent conflicts with the default drag behavior ). First, it ruled out whether it was caused by layout problems. Therefore, a simple page was created for testing and still failed. Google found that there was such a problem, and Google Reader also failed, mobile safari requires two fingers to complete partial scrolling. In order to solve this problem, continue to Google, and finally found the above article Article Use the touchmove event of mobile safari to simulate the effect of the scroll bar. Not much nonsense Code Function istouchdevice (){ Try { Document. createevent ("touchevent "); Return true; } Catch (e ){ Return false; } Function touchscroll (ID ){ If (istouchdevice () {// If touch events exist... VaR El = Document. getelementbyid (ID ); VaR scrollstartpos = 0; Document. getelementbyid (ID). addeventlistener ("touchstart", function (event ){ Scrollstartpos = This. scrolltop + event. Touches [0]. Pagey; Event. preventdefault (); }, False ); Document. getelementbyid (ID). addeventlistener ("touchmove", function (event ){ This. scrolltop = scrollStartPos-event.touches [0]. Pagey; Event. preventdefault (); }, False ); } Finally, use touchscroll ("myelement"); call this method by calling the element ID of overflow: auto.
