JS to get all the parts of the URL

First, explain the URL:
Refer to Baidu Encyclopedia: URL entries
URL: Uniform Resource Locator (Uniform Resource Locator, URL)
The complete URL consists of the following parts:
Scheme: // host: Port/path? Query # Fragment
Scheme: Communication Protocol
Common HTTP, FTP, Maito, etc.

HOST: Host
The host name or IP address of the server (Computer) Domain Name System (DNS.

Port: Port Number
INTEGER (optional) Default port used when the scheme is omitted. For example, the default port of HTTP is 80.

Path: Path
A string separated by zero or multiple "/" symbols. It is generally used to represent a directory or file address on the host.

Query: Query
Optional. Used for dynamic web pages (such as CGI, ISAPI, PHP/JSP/asp. net and other technologies to produce web pages) transmission parameters, can have multiple parameters, separated by the "&" symbol, each parameter name and value are separated by the "=" symbol.

Fragment: Information Fragment
String used to specify fragments in network resources. For example, if a webpage contains multiple glossary, you can use fragment to directly locate the glossary. (Also called anchor .)

For such a URL
Http://www.x2y2.com: 80/Fisker/post/0703/rows configurlocation.html? Ver = 1.0 & id = 6 # imhere
 
We can use JavaScript to obtain all the parts.
1, window. Location. href
The whole URL string (the complete address bar in the browser)
Returned value in this example: http://www.x2y2.com: 80/Fisker/post/0703/optional parameter location.html? Ver = 1.0 & id = 6 # imhere

2, window. Location. Protocol

URL protocol section
Returned value in this example: http:

3, window. Location. Host
Host part of the URL
Return Value in this example: www.x2y2.com

4, window. Location. Port

If the default port 80 is used (Update: Even if port 80 is added), the return value is not the default port 80, but an empty character.
Returned value in this example :""

5, window. Location. pathname
URL path (that is, the file address)
Returned value in this example:/Fisker/post/0703/window.location.html

6. Window. Location. Search
Query (parameter)
In addition to assigning values to dynamic languages, we can also assign values to static pages and use JavaScript to obtain expected parameter values.
Return Value in this example :? Ver = 1.0 & id = 6

7. Window. Location. Hash
Anchor
Returned value in this example: # imhere <src = "http://feeds.feedburner.com /~ S/Fisker? I = http://www.x2y2.com/fisker/post/0703/window.location.html "type =" text/JavaScript "charset =" UTF-8 ">
