parse json array to get key value pair

[Reshma77]

Hello All,

I am trying to populate key-value pair from multi row variable set of incident table. With below code I am getting JSON array

var gr = new GlideRecord('incident');
gr.addQuery('number=INC0001164');
gr.query();
if (gr.next()) {
var mrvs = gr.variables.employee_details;
gs.print(mrvs);
}

*** Script: [ {
  "name" : "7db62c631b655150ded9eca8ab4bcb90",
  "number" : "007810",
  "manager" : "ABC",
  "cost" : "01394040"
} ]

If I try to parse the multi row variable set (var Payload = JSON.parse(mrvs); gs.print(Payload);) I am getting below result

Script: [object Object]

Can somebody help to get only key value pair from the JSON array. I am using this code in template script that needs to be populated on the ticket
The format should look like below

Name: ABC

Number: INC0001164
Manager: XYZ

Thanks,

It looks like that  mrvs is already a json object, you don't need to use JSON.parse(mrvs) to convert it to a json object.

Try to  such as use mrvs[0] .name  to get the name...

Have a try !

Hello Reshma,

Using the following code, you can iterate through the JSON array and print the key-value pairs:

var gr = new GlideRecord('incident');
gr.addQuery('number', 'INC0001164');
gr.query();
if (gr.next()) {
var mrvs = gr.variables.employee_details;
var Payload = JSON.parse(mrvs);
for (var i = 0; i < Payload.length; i++) {
var obj = Payload[i];
var keys = Object.keys(obj);
for (var j = 0; j < keys.length; j++) {
var key = keys[j];
if (key == "name") {
gs.print("Name: " + obj[key]);
}
if (key == "manager") {
gs.print("Manager: " + obj[key]);
}
}
}
}

if (key == "name") {
gs.print("Name: " + obj[key]);
}

While using above code I am getting sys id of the field. How can I get the display value?

I have already tried getdisplayvalue() and tostring() methods it is giving me null value
