getPropertyNames() Function

• Introduced in version 1.3b48

Returns a String List or JSON Array containing the names of the Token Properties for the Current Token. The type of the value returned depends on the delimiter parameter. All names returned will be in lower case. Use getPropertyNamesRaw() to get the names as they are shown in Campaign Properties.

When a token is added to a campaign it inherits the currently defined properties of the current campaign. These properties are persistent in the token even if the properties are subsequently removed from the campaign. Properties that have been removed from the campaign are no longer editable via the Edit Token dialog but they are still present on the token and may be read and set with getProperty() and setProperty() respectively. To get all properties defined on a token, including those removed from the campaign, use getPropertyNames(). To see only the currently defined properties for the campaign, use getAllPropertyNames().

Usage

getPropertyNames()
getPropertyNames(delim)
getPropertyNames(delim, tokenRef)
getPropertyNames(delim, tokenRef, mapname)

Parameters

delim - The delimiter used to separate the values in the String List, defaults to ",". Returns a JSON Array if set to "json".
tokenRef - Either the token id or Token Name of the token which has its property names returned, defaults to the Current Token.
Note: This parameter can only be used in a Trusted Macro.
mapname - The name 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

To display the names of all of the properties on the current token use.

[h: names = getPropertyNames()]
[foreach(name, names, "<br>"): name]

Version Changes

1.3b49 - Added json delimiter option.
1.3b51 - Added id parameter option.
1.5.4 - Added mapname parameter option.
