微信的js里面的 iframe 代码
(function(){
var iframe = document.getElementsByTagName('iframe');
for (var i=0,il=iframe.length;i<il;i++) {
var a = iframe[i];
var src_ = a.getAttribute('src')||a.getAttribute('data-src')||"";
if(!/http(s)*\:\/\/v\.qq\.com\/iframe\/(preview|player)\.html\?/.test(src_)){
continue;
}
var vid = getQuery("vid",src_);
if(!vid){
continue;
}
vid=vid.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g,"");
a.removeAttribute('src');
var obj = window.__getVideoWh(a),
mydiv = document.createElement('img');
mydiv.className = "img_loading";
mydiv.src="data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVQImWNgYGBgAAAABQABh6FO1AAAAABJRU5ErkJggg==";
mydiv.setAttribute("data-vid",vid);
mydiv.style.cssText = "width: " + obj.w + "px !important;height: " + obj.h + "px !important;";
a.style.display = "none";
