var s =''http：// server / dir1 / dir2 / dir3 /'';
s = s.match （/ \ / \ /（[^ \ /] *）\ //）;
s = s [1];
alert（s）;

听起来像是正则表达式的工作：
函数extractDomain（url）{
var match = / \ / \ /（[^ \ /] *）\ // EXEC（URL）。 // regexp //（[^ /]）* /
if（match）{return match [1]; }
}

如何在''//'和最左边的单个
''/''之间提取所有内容？
< script type =" text / javascript">
var s =''http：// server / dir1 / dir2 / dir3 /'';
var start = s.indexOf（''//''）;
var end = s.lastIndexOf（''/''）;
alert（s.substring（开始+ 2，结束））;
< / script>
如果
string（或只有两个 - http：//）。
您还可以使用正则表达式来提取您需要的信息。
如果网址实际上是我在location对象中，您可以使用location.host和location.pathname< url：
信息.sun.com / source / 816-6408-10 / location.htmtarget =_ blank> http://docs.sun.com/source/816-6408-10/location.htm /> ;。

Thank you!

var s = ''http://server/dir1/dir2/dir3/'';
s = s.match(/\/\/([^\/]*)\//);
s = s[1];
alert(s);

Sounds like a job for regular expressions:
function extractDomain(url) {
var match = /\/\/([^\/]*)\//.exec(url); // regexp //([^/])*/
if (match) { return match[1]; }
}

<script type="text/javascript">
var s = ''http://server/dir1/dir2/dir3/'';
var start = s.indexOf(''//'');
var end = s.lastIndexOf(''/'');
alert(s.substring(start + 2, end));
</script>
This will fail in most interesting ways if there are no slashes in the
string (or only two - http://).
You can also use regular expressions to extract the information you
seek.
And if the url is actually in the location object, then you can extract
the information using location.host and location.pathname <url:
http://docs.sun.com/source/816-6408-10/location.htm />.
