It helps other templates detect what type of page they are on. It detects and groups all the different namespaces used on Wikipedia into several types:
For backwards compatibility this template also understands the old name image for file. But using image is now deprecated. Note! For most usage cases it might be better to use the simpler namespace detection templates. (See the see also section below.) Since this template is more prone to human errors such as misspelling the parameter names. 用法This template takes one or more parameters named after the different page types as listed above. Like this: {{namespace detect | main = Article text | talk = Talk page text | other = Other pages text }} If the template is on a main (article) page, it will return this:
If the template is on any other page than an article or a talk page it will return this:
The example above made the template return something for all page types. But if we don't use the other parameter or leave it empty then it will not return anything for the other page types. Like this: {{namespace detect | file = File page text | category = Category page text | other = }} On any pages other than file and category pages the code above will render nothing. By using an empty parameter you can make it so the template doesn't render anything for some specific page type. Like this: {{namespace detect | main = | other = Other pages text }} The code above will render nothing when on mainspace (article) pages, but will return this when on other pages:
DemospaceFor testing and demonstration purposes this template can take a parameter named demospace. Demospace understands any of the page type names used by this template, including the other type. It tells the template to behave like it is on some specific type of page. Like this: {{namespace detect | main = Article text | other = Other pages text | demospace = main }} No matter on what kind of page the code above is used it will return this:
It can be convenient to let your template understand the demospace parameter and send it on to the {{namespace detect}} template. Then do like this: {{namespace detect | main = Article text | other = Other pages text | demospace = {{{demospace|}}} }} If the demospace parameter is empty or undefined then the template will detect page types as usual. ParametersList of all parameters: {{namespace detect | main = ... | other = | demospace = {{{demospace|}}} / main / talk / user / wikipedia / file / mediawiki / template / help / category / portal / other }} Note: Empty values to the "main" ... "portal" parameters do have special meaning. Technical detailsNamespace "Image" was renamed to "File" on 11 December 2008. This template was updated to understand both names well before that, thus it still works fine. For backwards compatibility it still understands "image" both as a parameter name, such as "image = File page text", and as a value "demospace = image". If you intend to feed tables as content to the numbered parameters of this template, then you need to know this: Templates do have a problem to handle parameter data that contains pipes " For more technical details such as about "copying to other projects" and "CSS based namespace detection" see {{main talk other}} and its talk page. 參見</div>
