Module:If any equal: Difference between revisions

Module documentation[view] [edit] [history] [purge]

Main

This main function of this module checks all positional parameters to see if any of them is equal to the parameter |value=. If so, it will output "yes", otherwise "no".

If the plural |values= is used, then one or more alternative values may be specified.

Examples

• {{#invoke:If any equal|main|a|b|c|d|value=c}} gives
• {{#invoke:If any equal|main|a|b|c|d|value=r}} gives
• {{#invoke:If any equal|main|a|b|c|d|value=}} gives
• {{#invoke:If any equal|main|a|b|c|d|values=r, b}} gives

IfAnyEqual

The IfAnyEqual function works in a similar way, but instead takes the names of the parameters and checks these arguments of the parent frame.

Example

For example, if you have the following code on {{Template}}

{{#invoke:If any equal|IfAnyEqual|param1|param2|values=a, b, c}}

Then calling {{Template}} will give the following results:

• {{Template|param1=b|param2=f}} gives "yes"
• {{Template|param1=z|param2=k}} gives "no"
• {{Template|param2=a}} gives "yes"

Using a prefix

If a prefix is specified with |prefix= then the module will check any parameter that consists of that prefix and possibly a number afterwards.

Example

For example, if you have the following code on {{Template}}

{{#invoke:If any equal|IfAnyEqual|prefix=param|values=a, b, c}}

Then calling {{Template}} will give the following results:

• {{Template|param=b|param2=f}} gives "yes"
• {{Template|param1=z|param3=k}} gives "no"
• {{Template|param12=a}} gives "yes"
