Js 解析URL
例如 http://localhost:8888/search?wd=s#top
如何用js正则得到如下信息:

scheme: http
slash: //
host: localhost
port: 8888
path: /search
query: wd=s
hash:top
------解决方案--------------------

<script type="text/javascript">

var parser = document.createElement('a');

parser.href = "http://localhost:8888/search?wd=s#top";

parser.protocol; // => "http:"

parser.host;    // => "localhost:8888"

parser.hostname;  // => "localhost"

parser.port;      // => "8888"

parser.pathname;  // => "/search"

parser.hash;      // => "#top"

parser.search;    // => "?wd=s"

</script>
