Client Script calling Script Include returning null

[Community Alums]

I want show the user first name and mobile number when caller field changes. I am trying to use a client script to call a script include to do this. I did set Client callable to true .But I am getting null value.

client script:

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

    if (isLoading || newValue === '') {

        g_form.setReadOnly('u_custom_mobile', true);

        g_form.setReadOnly('u_first_name', true);

        return;

    }

    alert('Script Runs '+g_form.getValue('caller_id'));

    var gx = new GlideAjax('userDetails');

    gx.addParam('sysparam_name', 'callernameandphone');

    gx.addParam('sysparam_user', g_form.getValue('caller_id'));

    gx.getXML(getData);

    function getData(response) {

        var answer = response.responseXML.documentElement.getAttribute('answer');

        alert(answer);

        if(answer) {

            var temValue = answer.toString().split('|');

            g_form.setValue('u_custom_mobile', temValue[0]);

            g_form.setValue('u_first_name', temValue[1]);

        }

    }

}

Script Include:

var userDetails = Class.create();

userDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    callernameandphone: function() {

        var usrId = this.getParameter('sysparam_user');

        var gr = new GlideRecord('sys_user');

        if (gr.get(usrId)) {

            return gr.getValue('mobile_phone') + '|' + gr.getValue('first_name');

        }

    },

    type: 'userDetails'

});

// Please any one help me

Hello @Community Alums,

Please correct these two line syntax:

 gx.addParam('sysparm_name', 'callernameandphone');
gx.addParam('sysparm_user', g_form.getValue('caller_id')); 

Using getReference():

Client Script details:
Type: onChange
Table: Incident
Field Name: Caller
function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue == '') {
          return;
}
    var caller = g_form.getReference('caller_id');
g_form.setValue('department',caller.department);
g_form.setValue('location',caller.location);
g_form.setValue('email',caller.email);
g_form.setValue('name',caller.name);
g_form.setValue('Mobile phone',caller.mobile_phone);
}

If my answer is helpful please mark it as helpful or correct!!

Using "getReference" is not the best for performance reasons:

1. you are not using a call back function
2. it returns a light-weight GlideRecord with all the data in the record instead of just the bits we need
3. in your example, although NOT required by the OP, setting the Department and Location field would trigger 2 more calls back to the server to get the display values for those records

As I mentioned above, take a look at this post for an alternative method: TNT: Returning Data from GlideAjax Calls

Hi Nagarjuna,

Please try this once

var caller = g_form.getReference('caller_id', getDetails); // getDetails is our callback function  
function getDetails(caller) { //reference is passed into callback as first arguments
        g_form.setValue('u_custom_mobile', caller.mobile_phone);
        g_form.setValue('u_first_name', caller.first_name);
}

Ramesh
