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
