让innerHTML的脚本也可以运行起来
var fillHTML = function (el,HTMLString) { if (!el) return; if (window.ActiveXObject) { //For IE el.innerHTML = "<img style='display:none'/>" + HTMLString.replace(/<script([^>]*)>/ig, '<script$1 defer>'); el.removeChild(el.firstChild) } else { //For Mozilla,Opare var nSibling = el.nextSibling; var pNode = el.parentNode; pNode.removeChild(el); el.innerHTML = HTMLString; pNode.insertBefore(el,nSibling) } } 详细出处参考：http://www.jb51.net/article/236.htm
