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