让innerHTML里的script跑起来，我这乍就跑不起来呢？

楼上的说的没用。
1楼：这是XMLHTTP加载过来的，不一样。
2楼：正式用的页面前面有内容的。script没在第一行。继续等待奇迹出现………

感觉跟是不是从xmlhttp加载没关系，都是将js innerHTML操作，不过没试过，有空测试一下。

script 加个隐藏的span就可以了<html>
<head>
</head>
<body onload="aa()">
<div id="dv1"></div>
</body>
</html>
<script language="javascript" type="text/javascript" >
function aa()
{
document.getElementById("dv1").innerHTML="<span style='display:none'>1</span><scri"+"pt defer>alert(1)</sc"+"ript>";
alert(document.getElementById("dv1").innerHTML);
}
</script>参考文章 http://www.coolcode.cn/?p=117

我这个是XMLHTTP加载的另一个页面（这个页面可能是文字＋脚本）
不是直接innerHTML="<scr"+"ipt>"...这种。情况一样的。来个附件[1K]：http://jiaxue.10mb.cn/innerHTML.rar

不知你试了没？这是改过的A.html

xmlhttp.open("GET","A-1.html",false)
xmlhttp.send(null);
if(window.navigator.userAgent.indexOf("Firefox")>=1) //针对FF
{
    document.getElementById("oDiv").innerHTML = xmlhttp.responseText;
    var scripts = document.getElementById("oDiv").getElementsByTagName("script");
    for(var i=0;i<scripts.length;i++) //一段一段执行script
    {
        eval(scripts[i].innerHTML);
    }
}else if(window.navigator.userAgent.indexOf("MSIE")!=-1)
{
    var httpText = xmlhttp.responseText;
    httpText = httpText.replace(/<script[^>]*>/gi,"<script defer>")//因为<script defer>可以在IE上直接运行，所以把所有的script标签都替换成defer标记的script
    document.getElementById("oDiv").innerHTML = httpText;
}
</script></body>
</html>

8楼的方法有些复杂哦，太长了，有空再看。10CutBug，用遍历＋eval，简单易理解。不错。谢谢各位。

调试易

让innerHTML里的script跑起来，我这乍就跑不起来呢？
