3 全屏 （Making it full-screen， for ios）– 更像本地App
<metaname="apple-mobile-web-app-capable"content="yes">
4 改变状态栏 （Changing the phone status bar, for ios）
content属性default, black and black-translucent
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
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() ;} ...
7 检测屏幕是否旋转（Detect whether device supports orientationchange event, otherwise fall back to the resize event）
var supportsOrientationChange="onorientationchange"inwindow,
orientationEvent=supportsOrientationChange?"orientationchange":"resize";
window.addEventListener(orientationEvent,function() {
alert('HOLY ROTATING SCREENS BATMAN:'+window.orientation+" "+screen.width);
},false);

8 禁止webapp跳转到safari（for ios）
// Mobile Safari in standalone mode
if(("standalone"inwindow.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'innoddy&&noddy.href.indexOf('http')!== -1&&(noddy.href.indexOf(document.location.host)!== -1||remotes)) {
event.preventDefault();
document.location.href=noddy.href;
}
},false);
}
9 禁用手机号码链接（for ios）
<meta name="format-detection" content="telephone=no" />
