Detailed description of window.location method get URL

Uniform Resource Locator (uniform Resource Locator, URL) The complete URL is composed of these parts:

Scheme://host:port/path?query#fragment

Scheme: Communication protocol

Commonly used Http,ftp,maito, etc.

Host: Hosts

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.)

Example:

1, Window.location.href

Entire URL string (in the browser is the complete address bar)

return value: http://www. Dw. Cn:80/index.asp?id=209#asp

2,window.location.protocol

The protocol part of the URL

Return value: http:

3,window.location.host

The host part of the URL,

return value: www. Dw. cn

4,window.location.port

The port portion of the URL. If you use the default port 80 (update: Even if you added: 80), the return value is not the default 80 but the null character.

This example returns a value: null

5,window.location.pathname

The path portion of the URL (that is, the file address)

return value:/index.asp

6,window.location.search

The query (Parameters) section. In addition to assigning values to dynamic languages, we can also give static pages and use JavaScript to get the value of a parameter that is believed to be
