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
[edit]{{calculator ifenabled|enabled=Lets show a calculator widget {{calculator|type=number|size=4}}|disabled=Calculator widgets are not supported}}
Which outputs:
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. 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.
