iOS device, fixed layout problem

    Window.deviceid = ' {$deviceId}} ';    Window.ios = Navigator.userAgent.match (/(ipad|iphone|ipod)/g)? True:false;    if (IOS) {      iosversion = (!! Window.history &&!! Window.history.pushState? ' 4+ ': ' 4-');      if (!! Window.matchmedia) {iosversion = ' 5+ ';}    }    Window.getviewport = function () {    //Note viewport sizing broken in Android 2.x see http://stackoverflow.com/questions /6601881/problem-with-meta-viewport-and-android      var viewport = {              Left:window.pageXOffset,   /////HTTP www.quirksmode.org/mobile/tableViewport.html              top:window.pageYOffset,              width:window.innerWidth | | Documentelement.clientwidth,              height:window.innerHeight | | documentelement.clientheight      };      return viewport;    }

　

It can be elevated on Android, but there is a problem on the iOS machine.

On an iOS machine, you don't always get to the bottom by bottom, but by calculating the top position and then adjusting the position by Scrollto.

    Window.timedelay = +;    SetInterval (function () {      window.scrollto (0, 0);    }, Timedelay);
