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('/')
- };
- }
复制代码
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'
