isPropertyEmpty() Function
• Introduced in version 1.3b48
Returns
true
(1
) if the Token Property for a specific Token is empty. A Token Property is considered empty if it is NULL
; if an empty string (""
) has been assigned to it, it is not considered empty.
Note: If the token type sets a default value, this function will still see the property as empty. Try using json.isEmpty().Usage
isPropertyEmpty(property)
isPropertyEmpty(property, tokenRef)
isPropertyEmpty(property, tokenRef, mapRef)
Parameters
property
- The name of the property that has its value checked.tokenRef
- Either the tokenid
or Token Name of the token that has its value checked, defaults to the Current Token.Note: This parameter can only be used in a Trusted Macro.
mapRef
- The Name or ID of the map to find the token. Defaults to the current map.
Token IDs are unique, but Token Names can be duplicated. Using Token Name when more than one token has the same name can produce unexpected results.
Example
[r, if(isPropertyEmpty("propertyName")): propertyName = someDefaultValue]
