Populate group member based on group selected

[Bindhu1]

I have below 2 variable, based on group selection , group member should get populated [each group has only one member] 
1.approval_group: referring to sys_user_group table
2.approver: referring to sys_user table
tried below script, its not populating member, please help me here
------------------------------------------------------------------------------------
script include: 

var GetApproverByGroup = Class.create();
GetApproverByGroup.prototype = Object.extendsObject(AbstractAjaxProcessor, {
   getApprover: function() {
       var groupSysId = this.getParameter('sysparm_group');
       var userSysId = '';
       if (groupSysId) {
           var gr = new GlideRecord('sys_user_grmember');
           gr.addQuery('group', groupSysId);
           gr.query();
           if (gr.next()) {
               userSysId = gr.user.toString();
           }
       }
       return userSysId;
   }
});

Onchange client script : on change of group variable

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
       return;
   }
   var ga = new GlideAjax('GetApproverByGroup');
   ga.addParam('sysparm_name', 'getApprover');
   ga.addParam('sysparm_group', newValue);
   ga.getXML(function(response) {
       var approver = response.responseXML.documentElement.getAttribute("answer");
       if (approver) {
           g_form.setValue('approver', approver);
       }
   });
}

@Bindhu1 I already recommended this method in my above response. That you can use response string directly. 

Kindly mark my answer as helpful and accept solution if it helped you in anyway. This will help me be recognized for the efforts and also move this questions from unsolved to solved bucket.

Hi @Bindhu1 
Try below script. I just tested out in my PDI.
Script include:

getApprover: function() {
        var groupSysId = this.getParameter('sysparm_group');
        var userSysId = '';
        if (groupSysId) {
            var gr = new GlideRecord('sys_user_grmember');
            gr.addQuery('group', groupSysId);
            gr.query();
            if (gr.next()) {
                userSysId = gr.user.toString();
            }
        }
        return userSysId;
    },

Client script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var ga = new GlideAjax('GetApproverByGroup');
    ga.addParam('sysparm_name', 'getApprover');
    ga.addParam('sysparm_group', newValue);
    ga.getXMLAnswer(getResponse);
    //Type appropriate comment here, and begin script below

}
function getResponse(answer) {
    if (answer) {
        g_form.setValue('user', answer);
    }
}

Hello @Bindhu1 

Use below 👇 script include 

var GetApproverByGroup = Class.create();

GetApproverByGroup.prototype = Object.extendsObject(AbstractAjaxProcessor, {

   // Function to get the first group member

   getApprover: function() {

       var groupSysId = this.getParameter('sysparm_group');

       var userSysId = '';

       if (groupSysId) {

           // GlideRecord to get group members

           var gr = new GlideRecord('sys_user_grmember');

           gr.addQuery('group', groupSysId);

           gr.query();

           // Fetch the first user in the group

           if (gr.next()) {

               userSysId = gr.user.toString(); // Getting user Sys ID

           }

       }

       return userSysId; // Return user Sys ID

   }

});

Use below 👇 client script 

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

       return;

   }

   var ga = new GlideAjax('GetApproverByGroup');

   ga.addParam('sysparm_name', 'getApprover');

   ga.addParam('sysparm_group', newValue); // Send group Sys ID

   ga.getXML(function(response) {

       var approver = response.responseXML.documentElement.getAttribute("answer");

       if (approver) {

           g_form.setValue('approver', approver); // Set the approver field with the user Sys ID

 }

   });

}

Is the approver field also reference fields ? Because you are passing sys_id ? 

Also, is the Client script set to UI type ALl and the script include with "Client callable" box checked ? 

If all above is correct then make use of response directly to populate. 

Kindly mark my answer as helpful and accept solution if it helped you in anyway. This will help me be recognized for the efforts and also move this questions from unsolved to solved bucket.
