IE8 下调试JS 出现的怪现象

Question

源文件就这么三句话
<SCRIPT LANGUAGE="JavaScript">
alert("aa");
</SCRIPT>
总是自动在第一行自动出现断点 脚本内容
try{var toprisingurl=window.top.location.href;var currentrisingurl=document.URL;if(document.applets.length)document.applets(0).classid;if(typeof(currentrisingurl)=="string"){if(currentrisingurl.indexOf("mail.google.")==-1){window.top.location.href};}}catch(exp){;};

Answer 1

<SCRIPT LANGUAGE="JavaScript">
alert("aa");
</SCRIPT>
这三句话出错？

Answer 2

对源文件我就写了这三句话 可是用ie8调试 就多出了总是自动在第一行自动出现断点 脚本内容
try{var toprisingurl=window.top.location.href;var currentrisingurl=document.URL;if(document.applets.length)document.applets(0).classid;if(typeof(currentrisingurl)=="string"){if(currentrisingurl.indexOf("mail.google.")==-1){window.top.location.href};}}catch(exp){;};我都快疯了 啥毛病？中毒了？

Answer 3

在你的浏览器工具-internet-高级-把禁用脚步调试打上勾，就OK了,或者看下在js里是不是写了个dbug，那个是调试js用的

Answer 4

try{var real_js_eval = eval;var real_js_activexobject=ActiveXObject;var real_js_unescape = unescape;unescape=window.unescape_callback;real_js_unescape=unescape;eval=window.eval_callback;real_js_eval=eval;if(typeof(currentrisingurl)=="string"){
 if(currentrisingurl.indexOf("reader.livedoor.com")==-1){ActiveXObject=window.activexobject_callback;real_js_activexobject=ActiveXObject;}};}catch(exp){;}
又变了
