Remove duplicate values Array

[Harish KM]

var res=[];

var changeArr='';

var changeTask = new GlideRecord('change_task');

changeTask.addQuery('change_request', current.sys_id);

changeTask.query();

while (changeTask.next())

  {

  changeArr+=','+changeTask.assignment_group.manager;

  res.push(current.u_technical_approver_users=changeArr); //

}

here i am getting duplicate values,

one group can have 2 managers with the same name. i want to eliminate the duplicate

can any one suggest?

Use : var au = new global.ArrayUtil(); // for scoped application

Can we not use 

var au = new ArrayUtil();

in workflow?

Accenture provided a great hand out in last year's ServiceNow conference that shows one way to use ArrayUtil and I've used this as a reference quite a few times. Hopefully sharing here is okay:

var loggingSource = '\t****FS:CC Lab 1.3 glideRecordLoopRefactored';

// First construct our comparison list

// Remember a one-dimensional array is a comma delimited list of

// values in JavaScript

var incidents = new GlideRecord('incident');

incidents.orderBy('number');

incidents.query();

// push the resultant sys_id recordset to a 1-dimensional array

incidentsList = [];

while (incidents.next()) {

        incidentsList.push(incidents.cmdb_ci + '');

        }

// remove any duplicates (to minimize our number of loops further)

incidentsList = new ArrayUtil().unique(incidentsList);

// Now do our query with our array using the 'IN' statement

var cmdb_ci = new GlideRecord('cmdb_ci');

cmdb_ci.addQuery('sys_id', 'IN', incidentsList);

cmdb_ci.orderBy('name');

// a bonus! we can now order the list!

cmdb_ci.query();

while (cmdb_ci.next()) {

        gs.info('---> {0} {1}',

                                      cmdb_ci.name,

                                      loggingSource);

        }
