javascript中有时需要用到当前的请求路径等涉及到url的情况,正常情况下我们可以使用location对象来获取我们需要的信息,本文从另外一个途径来解决这个问题,而且更加巧妙
方法如下：
function parseurl(url) { var a = document.createelement('a'); //创建一个链接 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('/') }; }
使用方法如下：
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'
