wap页面的结构都放到 LM-wall320 里
<div id="LM-wall320"> ... </div>
通过js根据不同手机页面的宽度根据320计算 从顶部中间开始缩放
(function(){
var doc = document,
style=doc.createElement(‘style‘),
Timmer = null;
style.innerHTML = setStyle();
doc.getElementsByTagName(‘head‘)[0].appendChild(style);
/*屏幕翻转*/
window.addEventListener(window[‘onorientationchange‘] ? ‘orientationchange‘ : ‘resize‘, function(){
clearTimeout(Timmer);
Timmer = setTimeout(function(){
style.innerHTML = setStyle();
},100);
}, false);
/*生成样式*/
function setStyle(){
var w = doc.documentElement.clientWidth;
return ‘#LM-wall320{-webkit-transform:scale(‘+w/320+‘);-webkit-transform-origin:top center;}‘;
}
})();
