parseUrl函数

在外国一博客看到一个很好的

function parseURL(url) {

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

    a.href = url;

    return {

        source: url,

        protocol: a.protocol.replace(':',''),

        host: a.hostname,

        port: a.port,

        query: a.search,

        params: (function(){

            var ret = {},

                seg = a.search.replace(/^\?/,'').split('&'),

                len = seg.length, i = 0, s;

            for (;i<len;i++) {

                if (!seg[i]) { continue; }

                s = seg[i].split('=');

                ret[s[0]] = s[1];

            }

            return ret;

        })(),

        file: (a.pathname.match(/\/([^\/?#]+)$/i) || [,''])[1],

        hash: a.hash.replace('#',''),

        path: a.pathname.replace(/^([^\/])/,'/$1'),

        relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,''])[1],

        segments: a.pathname.replace(/^\//,'').split('/')

    };

}

用法：

var myURL = parseURL('http://abc.com:8080/dir/index.html?id=255&m=hello#top');

myURL.file;     // = 'index.html'

myURL.hash;     // = 'top'

myURL.host;     // = 'abc.com'

myURL.query;    // = '?id=255&m=hello'

myURL.params;   // = Object = { id: 255, m: hello }

myURL.path;     // = '/dir/index.html'

myURL.segments; // = Array = ['dir', 'index.html']

myURL.port;     // = '8080'

myURL.protocol; // = 'http'

myURL.source;   // = 'http://abc.com:8080/dir/index.html?id=255&m=hello#top'
