//需要使用的模塊 http   url
當(dāng)前url   http://localhost:8888/select?aa=001&bb=002
var http = require('http');
var URL = require('url');
http.createServer(function(req, res){
   var arg = url.parse(req.url).query; //方法一arg => aa=001&bb=002
   var arg = url.parse(req.url, true).query; //方法二arg => { aa: '001', bb: '002' }
   console.log(arg.aa);//返回001
   console.log(arg.bb);//返回002
   //然后就可以根據(jù)所得到的數(shù)據(jù)處理了

}).listen(8888);//建立服務(wù)器并監(jiān)聽(tīng)端口

獲取特定url參數(shù)值

復(fù)制代碼代碼如下:

var testUrl =  'http://localhost:8888/select?aa=001&bb=002';
var p = URL.parse(testUrl); 
console.log(p.href); //取到的值是：http://localhost:8888/select?aa=001&bb=002
console.log(p.protocol); //取到的值是：http: 
console.log( p.hostname);//取到的值是：locahost
console.log(p.host);//取到的值是：localhost:8888
console.log(p.port);//取到的值是：8888
console.log(p.path);//取到的值是：/select?aa=001&bb=002
console.log(p.hash);//取到的值是：null 
console.log(p.query);// 取到的值是：aa=001

在此值得注意的是當(dāng)語(yǔ)句是 var p = URL.parse(testUrl, true) 時(shí),p.query則返回的是如：{aa:'001'}這樣的對(duì)象，直接打印p.query則返回 [object Object]，這時(shí)我們可以這樣寫： console.log(p.query.aa); //取到的值是：001
console.log( p.pathname);//取到的值是：/select

下面附上js的獲取方法：
當(dāng)前URL

復(fù)制代碼代碼如下:

http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.location:        http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.URL:             http://mj_0203.0fees.net/index.php?aa=001&bb=002
document.location.href:   http://mj_0203.0fees.net/index.php?aa=001&bb=002
self.location.href:       http://mj_0203.0fees.net/index.php?aa=001&bb=002
top.location.href:        http://mj_0203.0fees.net/index.php?aa=001&bb=002
parent.document.location: http://mj_0203.0fees.net/index.php?aa=001&bb=002
top.location.hostname:    mj_0203.0fees.net
location.hostname:        mj_0203.0fees.net
