一个不错的JavaScript解析浏览器路径方法(转)

JavaScript中有时需要用到当前的请求路径等涉及到url的情况,正常情况下我们可以使用location对象来获取我们需要的信息,本文从另外一个途径来解决这个问题,而且更加巧妙

方法如下:

 1 function parseURL(url) {
 2 var a =  document.createElement('a');
 3 //创建一个链接
 4 a.href = url;
 5 return {
 6 source: url,
 7 protocol: a.protocol.replace(':',''),
 8 host: a.hostname,
 9 port: a.port,
10 query: a.search,
11 params: (function(){
12 var ret = {},
13 seg = a.search.replace(/^?/,'').split('&'),
14 len = seg.length, i = 0, s;
15 for (;i<len;i++) {
16 if (!seg[i]) { continue; }
17 s = seg[i].split('=');
18 ret[s[0]] = s[1];
19 }
20 return ret;
21 })(),
22 file: (a.pathname.match(//([^/?#]+)$/i) || [,''])[1],
23 hash: a.hash.replace('#',''),
24 path: a.pathname.replace(/^([^/])/,'/$1'),
25 relative: (a.href.match(/tps?://[^/]+(.+)/) || [,''])[1],
26 segments: a.pathname.replace(/^//,'').split('/')
27 };
28 }

使用方法如下:

 1 var myURL = parseURL('http://abc.com:8080/dir/index.html?id=255&m=hello#top');
 2 myURL.file;     // = 'index.html'
 3 myURL.hash;     // = 'top'
 4 myURL.host;     // = 'abc.com'
 5 myURL.query;    // = '?id=255&m=hello'
 6 myURL.params;   // = Object = { id: 255, m: hello }
 7 myURL.path;     // = '/dir/index.html'
 8 myURL.segments; // = Array = ['dir', 'index.html']
 9 myURL.port;     // = '8080'
10 myURL.protocol; // = 'http'
11 myURL.source;   // = 'http://abc.com:8080/dir/index.html?id=255&m=hello#top'
