模板:URL

Template documentation[view] [edit] [history] [purge]

This template is used in MediaWiki:Titleblacklist-custom-URL, and on approximately 386,000 pages, or roughly 8670% of all pages.
Changes to it can cause immediate changes to the Wikipedia user interface.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

This template uses Lua:

Module:URL

This template creates a formatted external link. It formats the appearance of displayed URLs, while making them machine-readable as part of emitted microformat meta-data, inside templates such as infoboxes.

Note: If you wish to display text instead of the URL (e.g. website instead of example.com), please do not use this template. Instead, consider using normal wiki markup or Template:Official website. Displaying text instead of the url will render the microformat data invalid.

For web-based references, please see Wikipedia:Citation templates.

Usage

{{URL|example.com}}
- The first parameter is parsed to decide whether it is a complete URL. If it doesn't start with a URI scheme (such as "http:", "https:", or "ftp:"), the prefix "http://" is prepended to the specified generated target URL of the link.
- Parameter 2 ({{URL|url name|optional display text}}) is deprecated. See note above for more information and alternative templates.

URL with = character should use numbered parameters

If the URL contains an equals sign, as is common in a query string, the parameter |1= should be used for the URL ({{URL|1=example.com}}). This applies when the value of the URL is unknown, for example, when this template is used in another template specifying the effective URL as a variable value 模板:Nowiki template demo

The template attempts to handle simple cases where a URL containing an equals sign is specified without the necessary |1=, but it is still better practice to pass it in.

The deprecated second parameter for the displayed text, if present in legacy uses, must also be explicitly numbered if the first parameter is explicitly numbered ({{URL|1=url name|2=optional display text}}); otherwise it will override the value of the first parameter: 模板:Nowiki template demo

Examples

The template displays an instructional message if there is no input: 模板:Nowiki template demo

The template wraps the output in span class="url">>...</span> (see § Microformat) and adds <wbr/> before displayed periods: 模板:Nowiki template demo

The use of http://, https://, a protocol-relative URL, or a different protocol is preserved in the URL but is not shown in the link text: 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo

If the path is only a slash (/) it is not displayed in the link text: 模板:Nowiki template demo

The template also adds <wbr/> before any displayed slashes (/) in the path: 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo

Upper case in the domain name is preserved in the URL, but not in the link text (upper case in the path is not changed): 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo

For a URL containing an equal sign (=), use |1=: 模板:Nowiki template demo 模板:Nowiki template demo

The template currently supports an optional second parameter which is used as the link text, though its use is discouraged (see note): 模板:Nowiki template demo 模板:Nowiki template demo 模板:Nowiki template demo

The URL may be obtained from Wikidata as shown in this example for Lua错误在模块:Wd的第621行：attempt to index field 'wikibase' (a nil value) (Q23317), where the property 模板:Prop contains : 模板:Nowiki template demo

Microformat

The template wraps the displayed URL with a class="url" so that it is included in any parent microformat which takes a URL parameter – see our microformats project.
