Fetch values from JSON.parse(answer);

[SNOW32]

Hi All,

As I am beginner in coding I am not able to fetch choices option in for loop when using JSON.parse(answer); Getting wrong result(below) in comma separated and in single line. It should be like options.

How to achieve it? Please let me know what to modify in my code. Here is my code below:

 var obj = JSON.parse(answer);
 alert(answer);
 g_form.clearOptions('u_service_name');
  for(var i=0; i<obj.length; i++)
         {
             g_form.addOption('u_service_name', obj[i],obj[i]);
            
    }

i am assuming here you have fetched choice label and value in json , validate your server side code, in which object you have stored the label and value .

in server side your script should be like, 

var obj ={};

obj.lab = gliderecordobject.label;

obj.val =gliderecordobject.value;

in client script 

 var obj = JSON.parse(answer);
 alert(answer);
 g_form.clearOptions('u_service_name');
  for(var i=0; i<obj.length; i++)
         {
             g_form.addOption('u_service_name', obj[i].value,obj[i].lab);
            
    }

Hi Harshvardhan,

My script include code is below. It returns value of choices in comma separated manner

var ci = this.getParameter('sysparam_caller');
var gr = new GlideRecord('u_cx_service_name');
gr.addQuery('u_configuration_item', ci);
gr.query();
var arrReturn = [];
while (gr.next())
            {
              
                arrReturn.push( gr.u_service_names.getDisplayValue().toString());
        
            }
     return JSON.stringify(arrReturn);       

In client script , alert(answer) is showing like below:

Please help how to do it.

try now. 

var ci = this.getParameter('sysparam_caller');
var gr = new GlideRecord('u_cx_service_name');
gr.addQuery('u_configuration_item', ci);
gr.query();
var arrReturn = [];
while (gr.next())
            {

var obj = {};

obj.lab = gr.getDisplayValue('u_service_names'),

obj.val =gr.getValue('u_service_names')

              
                arrReturn.push(obj);
        
            }
     return JSON.stringify(arrReturn);

     var obj = JSON.parse(answer);
 alert(answer);
 g_form.clearOptions('u_service_name');
  for(var i=0; i<obj.length; i++)
         {
             g_form.addOption('u_service_name', obj[i].val,obj[i].lab);
            
    }

change this line as well , it's wrong. 

var ci = this.getParameter('sysparam_caller'); 

updated line. 

var ci = this.getParameter('sysparm_caller');
