• Introduced in version 1.3b53
Returns a JSON Array with the intersection of all of the JSON Object keys or JSON Array values. An value or key only appears in the output if it exists in all input arrays or objects. This function is useful for removing Token IDs from a saved list which have been deleted from the map by eliminating them using this function, the saved array and getTokens().
Usage
json.intersection(array, array, ...)json.intersection(object, object, ...)Parameters
array- A JSON Array used in the intersection.object- A JSON Object used in the intersection.
Examples
[h: array1 = json.append("",1,2,3,4)]
[h: array2 = json.append("",3,4,5,6)]
[r: json.intersection(array1,array2)]Returns
"[3,4]"
[h: arrayOfSelectedNames = getSelectedNames("json")]
[h: arrayOfNamesOnMap = getTokenNames("json")]
[r: json.intersection(arrayOfSelectedNames,arrayOfNamesOnMap)]Input
arrayOfSelectedNames = ["Alexander","Josh"] arrayOfNamesOnMap = ["Kevin","Josh","Alexander"]
Returns
["Alexander","Josh"]
