URL is: Uniform Resource Locator (uniform Resource Locator, URL)
The complete URL is composed of these parts:
Scheme://host:port/path?query#fragment
Scheme: Communication protocol
Common Http,ftp,maito Host: mainframe
Server (computer) domain Name System (DNS) host name or IP address. Port: Port number
Integer, optional, omit when using the default port of the scheme, such as HTTP's default port is 80. Path: Paths
A string separated by 0 or more "/" symbols, typically used to represent a directory or file address on a host. Query: Querying
Optional for dynamic Web pages, such as using CGI, ISAPI, php/jsp/asp/asp. NET, and other technology-made pages, can have multiple parameters, separated by the "&" symbol, and the name and value of each parameter are separated by the "=" symbol. Fragment: Pieces of information
A string that specifies the fragment in the network resource. For example, a Web page has multiple noun interpretations, which can be directly positioned to a noun interpretation using fragment. (also known as anchor points.) For such a URL http://www.x2y2.com:80/fisker/post/0703/window.location.html?ver=1.0&id=6#imhere
We can use JavaScript to get every part of it.
1, Window.location.href
Entire URL string (in the browser is the complete address bar)

This example returns a value of:/fisker/post/0703/window.location.html 6,window.location.search
