用javascript替换URL中的参数值的技巧
今天遇到一个需要用javascript将url中的某些参数替换的需求: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('/') }; }
用法：
var myURL = parseURL('http://docs.jayzou.com/?default.aspx?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://www.jayzou.com 取得URL的参数，以对象形式返回！
var getParam = function(path){ var result = {},param = /([^?=&]+)=([^&]+)/ig,match; while((match = param.exec(path)) != null){ result[match[1]] = match[2]; } return result; } ?Object.keys = Object.keys || function(obj){ var result = []; for(var i in obj){ if(obj.hasOwnProperty(i)){ result.push(i) } } return result; } var path = "http://www.jayzou.com/f?ct=318767104&tn=baiduKeywordSearch&sc=1&pn=0&rn=50&lm=4&rs4=2&rs3=2&word=%D0%C2%BE%D3%D5%D1%C4%CB&frs=jpq"; ?var r = getParam(path); alert(Object.keys(r))//ct,tn,sc,pn,rn,lm,rs4,rs3,word,frs
