本文内容很简单，给大家总结一下javascript获得当前的信息的一些常用命令
console.info("document.URL=" + document.URL);
console.info("document.location.href=" + document.location.href);
//console.info("document.base=" + document.base); //这是错的!
console.info("document.location=" + document.location);
console.info("self.location.href=" + self.location.href);
console.info("top.location.href=" + top.location.href);
console.info("location.hostname=" + location.hostname);
console.info("window.location.host=" + window.location.host);
console.info("window.location.pathname=" + window.location.pathname);
暂时想起来的就这些啦，后续再更新^_^
