remove duplicates from array

[gtk]

on scoped application form we have requested for, opened by and watchlist

1. trying to push all these values into any array 'a1'

2. tries using var au =  gloabl.ArrayUtils();

au.unique(a1);

not getting result from business rule and the same is applied on Background script , in BG it is working but not in BR

var currentWL = "9171f4e087f50d9471760dcd8bbb3506,9171f4e087f50d9471760dcd8bbb3506,d69e968b4796015011097601e36d4303,0c8f67761b035810acb7b887cc4bcb0d";



var updatedWL = currentWL ;
gs.info ("Updated Watch List is " + updatedWL);

var emailArray = updatedWL.split(',');

var arrayUtil = new global.ArrayUtil();
//with duplicates
gs.info("final array = "+emailArray);

var finalArray = arrayUtil.unique(emailArray);
//without duplicates
gs.info("result array = "+finalArray.toString());

any help appreciated

Hi @gtk ,

Can you give more context about your problem, and maybe all your code (you say, you are trying to push the variable in au, but i cant see in the code the variable). That looks the problem is in the logic insted of servicenow apis.

@Marco0o1 , thanks for your interest

var a1 = []; // new array

a1.push(current.caller); // send caller to array

var watchlist = current.watchlist.toString();

a1.push(watchlist);//send wathlist to array

a1.push(current.opened_by); // send opened by to array

gs.inof(a1);

now if caller is also available in watchlist, then remove duplicates

//use arraytuils script include to remove duplicates from array

var au = new global.Arrayutil();

var autil = au.unique(a1);

gs.info(autil);

// here I am not able to remove duplicates from array

If you are just trying to delete the duplicate items tried something like this:

var a1=[] // Store the data localy, original and duplicates
 a1.push(current.caller); // send caller to array
var watchlist = current.watchlist.toString();
 a1.push(watchlist);//send wathlist to array
 a1.push(current.opened_by); // send opened by to array
var au = []; // new array

//Delete the duplicated items with 
for (var i = 0; i < a1.length; i++) {
// In the iff condition the indexOf return -1 if not exist that element in the array and insert in the au array
  if (au.indexOf(a1[i]) === -1) {
    au.push(a1[i]);
  }
}
gs.inof(a1); //a1 contain original and duplicated values
gs.inof(au); //au contain not duplicated values

Or tried : 

var a1=[] // Store the data localy, original and duplicates
 a1.push(current.caller); // send caller to array
var watchlist = current.watchlist.toString();
 a1.push(watchlist);//send wathlist to array
 a1.push(current.opened_by); // send opened by to array
var au = a1.reduce(function (accumulator, currentValue) {
  if (accumulator.indexOf(currentValue) === -1) {
    accumulator.push(currentValue);
  }
  return accumulator;
}, []);


gs.inof(a1); //a1 contain original and duplicated values
gs.inof(au); //au contain not duplicated values

I hope that cant help you, if you dont understand just look for delete duplicate items in array in the internet.
