对于window.location，我们比较熟悉，它有protocol，hostname，host，port，search，hash，href，pathname等属性，a标签也和window.location一样，也有这样属性，这样可以方便我们分析网址，闲话少说，上代码。

function parseURL(url) { var a = document.createElement('a'); a.href = url; return { source: url, protocol: a.protocol.replace(':',''), host: a.hostname, port: a.port||'80', 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('/') }; }

测试地址

console.log(parseURL("http://www.w3school.com.cn/jsref/dom_obj_anchor.asp"));

结果如下

复制代码 代码如下:

{

file: "dom_obj_anchor.asp",

hash: "id2",

host: "www.w3school.com.cn",

params: {type: "2"},

path: "/jsref/dom_obj_anchor.asp",

port: "80",

protocol: "http",

query: "",

relative: "/jsref/dom_obj_anchor.asp",

segments: [0: "jsref",1: "dom_obj_anchor.asp"],

source: http://www.w3school.com.cn/jsref/dom_obj_anchor.asp?type=2#id2

}
