说明新浪主要是根据时间段来显示不同的广告,然后将动态控制iframe来显示广告
有个重要的文件
http://ad4.sina.com.cn/sina/ae/ad_src/fullscreen/fullscreenv2.html
的代码如下,用${}作为分割符,利用了数组

复制代码 代码如下:

<script> <BR>var par = location.search.substr(1); <BR>var ary = par.split("${}"); <br><br>document.writeln("<a href='" + ary[0] + "' target=_blank><img src="/static/imghw/default1.png" data-src=" + ary[1] + " class="lazy" style="max-width:90%"从新浪弄下来的全屏广告代码 与使用说明_广告代码" >"); <BR></script>

ary[0]为连接地址
ary[1]为图片地址
