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 yes{{#invoke:If any equal|main|a|b|c|d|value=r}}gives no{{#invoke:If any equal|main|a|b|c|d|value=}}gives no{{#invoke:If any equal|main|a|b|c|d|values=r, b}}gives yes
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:Template link}}
{{#invoke:If any equal|IfAnyEqual|param1|param2|values=a, b, c}}
Then calling {{Template:Template link}} will give the following results:
{{Template:Template link|param1=b|param2=f}}gives "yes"{{Template:Template link|param1=z|param2=k}}gives "no"{{Template:Template link|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:Template link}}
{{#invoke:If any equal|IfAnyEqual|prefix=param|values=a, b, c}}
Then calling {{Template:Template link}} will give the following results:
{{Template:Template link|param=b|param2=f}}gives "yes"{{Template:Template link|param1=z|param3=k}}gives "no"{{Template:Template link|param12=a}}gives "yes"
