下面是相关的应用与知识点: 
window.location.href 
window.top.location.replace("http://www.jb51.net") 
top.location.href("http://www.jb51.net") 
window.navigate ("http://www.jb51.net") 
Html: 
 
--------------------------------------- 
URL即:统一资源定位符 (Uniform Resource Locator, URL) 
完整的URL由这几个部分构成: 
scheme://host:port/path?query#fragment 
scheme:通信协议 
常用的http,ftp,maito等 
host:主机 
服务器(计算机)域名系统 (DNS) 主机名或 IP 地址。 
port:端口号 
整数,可选,省略时使用方案的默认端口,如http的默认端口为80。 
path:路径 
由零或多个"/"符号隔开的字符串,一般用来表示主机上的一个目录或文件地址。 
query:查询 
可选,用于给动态网页(如使用CGI、ISAPI、PHP/JSP/ASP/ASP.NET等技术制作的网页)传递参数,可有多个参数,用"&"符号隔开,每个参数的名和值用"="符号隔开。 
fragment:信息片断 
字符串,用于指定网络资源中的片断。例如一个网页中有多个名词解释,可使用fragment直接定位到某一名词解释。(也称为锚点.) 
对于这样一个URL 
http://www.jb51.net:80/fisker/post/0703/window.location.html?ver=1.0&id=6#imhere 

我们可以用javascript获得其中的各个部分 
1, window.location.href 
整个URl字符串(在浏览器中就是完整的地址栏) 
本例返回值: http://www.jb51.net:80/fisker/post/0703/window.location.html?ver=1.0&id=6#imhere 
2,window.location.protocol 
URL 的协议部分 
本例返回值:http: 
3,window.location.host 
URL 的主机部分 
本例返回值:www.jb51.net 
4,window.location.port 
URL 的端口部分 
如果采用默认的80端口(update:即使添加了:80),那么返回值并不是默认的80而是空字符 
本例返回值:"" 
5,window.location.pathname 
URL 的路径部分(就是文件地址) 
本例返回值:/fisker/post/0703/window.location.html 
6,window.location.search 
查询(参数)部分 
除了给动态语言赋值以外,我们同样可以给静态页面,并使用javascript来获得相信应的参数值 
本例返回值:?ver=1.0&id=6 
7,window.location.hash 
锚点 
本例返回值:#imhere
