How to compare two list fields

[Indirakumar2]

Hi,

I wanted to compare two list fields(u_groups,u_approver_groups) and return the left out value and update the list field "u_approver_groups" with the left out value.

Client Script

function onLoad() {
var requestedBy = g_form.getReference('cmdb_ci',setGroup);

}
function setGroup(requestedBy)
{
var array1=[];
array1=requestedBy.u_groups;//list field contains multiple groups
alert("The array1 is :"+array1);
var array2 = [];
array2= g_form.getValue('u_approver_groups');//list field in change form contains multiple groups
alert("The array2 is :"+array2);
var array3 = [];

for(var i = 0; i <= array1.length; i++)
{
if(array2.indexOf(array1[i]) == -1){
array3.push(array1[i]);

}
}
alert("The array3 is :"+array3);// It returns empty ,I want to return the groups which are present extra in array1

}

But works fine in the below scenario:

function onLoad() {

var array1=['0a52d3dcd7011200f2d224837e6103f2','3cc3c7680b982300cac6c08393673a03','2156c3a80b982300cac6c08393673a7e'];
var array2 = ['0a52d3dcd7011200f2d224837e6103f2','3cc3c7680b982300cac6c08393673a03'];
var array3 = [];
for(var i = 0; i <= array1.length; i++)
{
if(array2.indexOf(array1[i]) == -1){
array3.push(array1[i]);// This returns 2156c3a80b982300cac6c08393673a7e

}
}

}

Thanks in advance

Hi Inderjit,

Try replacing

array1=requestedBy.u_groups; 

with

array1=requestedBy.u_groups.split(',');
