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('https://www.jb51.net/') }; }
测试地址
console.log(parseURL("http://www.w3school.com.cn/jsref/dom_obj_anchor.asp?type=2#id2"));
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: "?type=2",
relative: "/jsref/dom_obj_anchor.asp?type=2#id2",
segments: [0: "jsref",1: "dom_obj_anchor.asp"],
source: ?type=2#id2
}
