Template:Calculator ifenabled/doc

Allows you to detect if the calculator gadget is enabled and provide fallback content for cases where it is not such as when printing. See {{Calculator}} for details on the calculator template system.

Usage

{{calculator ifenabled|enabled=Lets show a calculator widget {{calculator|type=number|size=4}}|disabled=Calculator widgets are not supported}}

Which outputs:

Lets show a calculator widget

Calculator widgets are not supported

If you add the scoped parameter, then calculators inside the enabled branch do not affect other calculators on the page. There is also a refreshonload parameter to force a refresh on first page load instead of first interaction as usual (this only works if scoped is set). For example:

{{calculator ifenabled|scoped=true|enabled=Lets show a calculator widget: {{calculator|type=number|id=x|size=2}}. The value of X is: {{calculator|type=text|readonly=1|formula=x|default=0|size=2}}.}} The X over here ( {{calculator|type=text|readonly=1|formula=x|default=0|size=2}} ) does not get updated, as the previous {{tl|calculator ifenabled}} is scoped.

Lets show a calculator widget: . The value of X is: 0.

{{{disabled}}}

The X over here ( 0 ) does not get updated, as the previous {{calculator ifenabled}} is scoped.
