This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This Lua module is used in system messages, and on approximately 1,050,000 pages, or roughly 2% 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 module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
This module depends on the following other modules: |
This module implements the {{Clickable button}} template.
Usage from wikitext
To use this module from wikitext, you should normally use the {{Clickable button}} template. However, it can also be used with the syntax {{#invoke:Clickable button|main|args}}
. Please see the template page for a list of available parameters.
Usage from Lua modules
To use this module from other Lua modules, first load the module.
local mClickableButton = require('Module:Clickable button')
You can then generate a button using the main function.
mClickableButton.main(args)
The args variable should be a table containing the arguments to pass to the module. To see the different arguments that can be specified and how they affect the module output, please refer to the {{Clickable button}} template documentation.
