[解决办法]
<img src="http://www.wineimg.com/userfiles/image/2013/01/20/SuperStar_24.jpg" width="131" height="35" alt="iframe 里的src传递参数有关问题" onclick="dd.call(this);" />
<iframe id='oframe' width="100%" height="500" frameborder="0" scrolling="no" src="http://widget.weibo.com/livestream/listlive.php?language=zh_cn&width=0&height=500&uid=&skin=1&refer=1&appkey=&pic=0&titlebar=1&border=1&publish=1&atalk=1&recomm=0&at=0&atopic=&ptopic=%E9%85%92%E7%BE%8E%E7%BD%91&dpc=1">

function dd(){
var id = window.dialogArguments;
var url = "http://widget.weibo.com/livestream/listlive.php?language=zh_cn&width=0&height=500&uid=&skin=1&refer=1&appkey=&pic=0&titlebar=1&border=1&publish=1&atalk=1&recomm=0&at=0&atopic=" + "&ptopic="+this.alt;

document.getElementById("oframe").src = url;
}

行了，只要src被赋值，iframe本就会重新加载
