5 阻止缩放（Preventing scaling）

<meta name="viewport" content="user-scalable=no, width=device-width" />

6 阻止弹性滚动（Preventing elastic scrolling）

<script>function BlockMove(event) { //Tell Safari not to move the window. event.preventDefault() ;}</script><body ontouchmove="BlockMove(event);" > ...</body>

7 检测屏幕是否旋转（Detect whether device supports orientationchange event, otherwise fall back to the resize event）

//Detect whether device supports orientationchange event, otherwise fall back to//the resize event.var supportsOrientationChange = "onorientationchange" in window, orientationEvent = supportsOrientationChange ? "orientationchange" : "resize";window.addEventListener(orientationEvent, function() { alert('HOLY ROTATING SCREENS BATMAN:' + window.orientation + " " + screen.width);}, false);

// Mobile Safari in standalone modeif (("standalone" in window.navigator) && window.navigator.standalone) { // If you want to prevent remote links in standalone web apps opening Mobile Safari, change 'remotes' to true var noddy, remotes = false; document.addEventListener('click', function(event) { noddy = event.target; //Bubble up until we hit link or top HTML element. Warning: BODY element is not compulsory so better to stop on HTML while (noddy.nodeName !== "A" && noddy.nodeName !== "HTML") { noddy = noddy.parentNode; } if ('href' in noddy && noddy.href.indexOf('http') !== -1 && (noddy.href.indexOf(document.location.host) !== -1 || remotes)) { event.preventDefault(); document.location.href = noddy.href; } }, false);}
