Set dynamic key value in json

[Eash1]

I am trying to set dynamic value to my Key in Json object but its setting the variable name instead.

var primaryObj = source.u_bp_primary_object_type.toString(); //dynamic values
var secondayObj = source.u_bp_secondary_object_type.toString(); //dynamic values

var payload = {
"app_key": appKey.toString(),
"status": source.u_bp_incident_status.toString(),
primaryObj : source.u_bp_primary_objects.toString(),  // Issue in line
secondayObj : source.u_bp_secondary_objects.toString(), //Issue in line
"servicenow_ticket_created": "false"
};

When i print the obj - 

{

"app_key": "123123",

"status":"warning",

"primaryObj":"RTUS00375SV001",

"secondayObj":"High Memory - Warning",

"servicenow_ticket_created":"false"

}

how to add dynamic key to json object.

Thank you,

Easwar

Try setting those properties after creating the object. 

Try the following code:

var primaryObj = source.u_bp_primary_object_type.toString(); //dynamic values
var secondayObj = source.u_bp_secondary_object_type.toString(); //dynamic values

var payload = {
"app_key": appKey.toString(),
"status": source.u_bp_incident_status.toString(),
"servicenow_ticket_created": "false"
};

payload[primaryObj] = source.u_bp_primary_objects.toString();
payload[secondayObj] = source.u_bp_secondary_objects.toString();

Here's the example I tried:

var dynamicKey = "value3"; 
var payload = { 
"value1": "text1", 
"value2" : "text2", 
}; 
payload[dynamicKey] = "text3"; 


gs.print(JSON.stringify(payload));

 Results:

*** Script: {"value1":"text1","value2":"text2","value3":"text3"}

Hope this helps!
