json.intersection() Function
• Introduced in version 1.3b53
Returns a JSON Array with the intersection of all of the JSON Object keys or JSON Array values. A 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"]
