JS解析URL字符串实现与PHP parseURL一样,方便了URL取参数与分析的繁琐。
function parseURL(url) { var a = document.createElement('a'); 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('/') }; } /* 1 var myURL = parseURL('http://abc.com:8080/dir/index.html?id=255&m=hello#top'); 2 myURL.file; // = 'index.html' 3 myURL.hash; // = 'top' 4 myURL.host; // = 'abc.com' 5 myURL.query; // = '?id=255&m=hello' 6 myURL.params; // = Object = { id: 255, m: hello } 7 myURL.path; // = '/dir/index.html' 8 myURL.segments; // = Array = ['dir', 'index.html'] 9 myURL.port; // = '8080' 10 myURL.protocol; // = 'http' 11 myURL.source; // = 'http://abc.com:8080/dir/index.html?id=255&m=hello#top' */
