利用a标签自动解析URL

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。

 1 function parseURL(url) { 2     var a =  document.createElement(‘a‘); 3     a.href =http://www.mamicode.com/ url; 4     return { 5         source: url, 6         protocol: a.protocol.replace(‘:‘,‘‘), 7         host: a.hostname, 8         port: a.port||‘80‘, 9         query: a.search,10         params: (function(){11             var ret = {},12                 seg = a.search.replace(/^\?/,‘‘).split(‘&‘),13                 len = seg.length, i = 0, s;14             for (;i<len;i++) {15                 if (!seg[i]) { continue; }16                 s = seg[i].split(‘=‘);17                 ret[s[0]] = s[1];18             }19             return ret;20         })(),21         file: (a.pathname.match(/\/([^\/?#]+)$/i) || [,‘‘])[1],22         hash: a.hash.replace(‘#‘,‘‘),23         path: a.pathname.replace(/^([^\/])/,‘/$1‘),24         relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,‘‘])[1],25         segments: a.pathname.replace(/^\//,‘‘).split(‘/‘)26     };27 }

测试地址

console.log(parseURL("http://www.w3school.com.cn/jsref/dom_obj_anchor.asp?type=2#id2"));

结果如下

 1 { 2     file: "dom_obj_anchor.asp", 3     hash: "id2", 4     host: "www.w3school.com.cn", 5     params: {type: "2"}, 6     path: "/jsref/dom_obj_anchor.asp", 7     port: "80", 8     protocol: "http", 9     query: "?type=2",10     relative: "/jsref/dom_obj_anchor.asp?type=2#id2",11     segments: [0: "jsref",1: "dom_obj_anchor.asp"],12     source: "http://www.w3school.com.cn/jsref/dom_obj_anchor.asp?type=2#id2"13 }
