详解javascript获取url信息的常见方法

var a=location.href;console.log(a);　// “http://www.cnblogs.com/wuxibolgs329/p/5261577.html#flag?test=12345”

var host = window.location.host; //www.cnblogs.comvar host2 = document.domain; //www.cnblogs.comvar a = location.hostname;　　//www.cnblogs.com

var a=location.protocol;console.log(a);　//http:

var a=location.port;console.log(a);

var a=location.pathname;console.log(a);

var a=window.location.hash; var b=a.substr(1); console.log(b);　// flag?test=12345

// 此时案例地址变为“http://www.cnblogs.com/wuxibolgs329/p/5261577.html?test=12345”。得到 test=12345var a=location.search;var b=a.substr(1);console.log(b);　//如果案例依旧是“http://www.cnblogs.com/wuxibolgs329/p/5261577.html#flag?test=12345”，则需下面的写法，得到 test=12345var a=location.href;var b=a.substr(a.lastIndexOf('?')+1);console.log(b);

var a=location.href;var b=a.substring(a.lastIndexOf('=')+1);console.log(b); // 12345
