Template:Ifnoteq then show/doc

维基百科,自由的百科全书

This template tests whether the first unnamed parameter is equal to the second unnamed parameter and returns the third unnamed parameter if it does. Otherwise it returns the first unnamed parameter.

This is useful when the first parameter is a {{#invoke: }} of a Lua module that returns a value for which a specific exception is required. Because it uses the {{#invoke: }} just once, it simplifies the coding of infoboxes, for example.

用法

An infobox field may return the 国家 (P17) for an article about a city. We may wish to use the abbreviation "USA" in place of "United States".
