上次已经揭贴子了的问题，Javascript如何获取当前页面的正确路径！

[gdmm]

pagename="http://expert.csdn.net/Expert/PostNew.asp?room=301"
能够正确解决，但是
pagename="http://expert.csdn.net:12345/mail.dll?View=Main"
又报告错了啊！

函数如下：

var pagename = window.location.href
function getHost(str)
{
var regUrl = /(\w+):\/\/([\w.]+)\/(\S*)/;
var result = str.match(regUrl);
if(result!=null) {
host=result[2].replace(/\b[\w]+\./,"");
return host;
}
}
//document.write (getHost(pagename))

<script>
x="http://expert.csdn.net:12345/mail.dll?View=Main"
x=x.substr(0,x.indexOf("/",8))
alert(x)
x=x.substr(x.indexOf(".")+1)
alert(x)
if(x.indexOf(":")>-1) x=x.substr(0,x.indexOf(":"))
alert(x)
</script>

<script>
<!--
var x = document.URL;
var y = x.substr(x.indexOf(".")+1);
var z = y.substring(0,y.indexOf("/"));
var su = x + "\n" + y + "\n" + z + "\n";
alert(su);
-->
</script>
