how to get original value instead of sys id

[Vikram Meena]

Hi,

I am using getReference on catalog client script and also getting value fine but one of value i am getting is sys id but i want its text value ie display value not sys id . i use getDisplayValue() or display box but nothing is working 

code look like..

var caller = g_form.getReference("variables.user",callback);

function callback(caller){

var location = caller.location;// getting sys id  

// Need to change this sys id into display value format

g_form.setValue("variables.location",location);

}

Thanks in advance

Following will get Incident's caller username in field 'username'.

I have client script on reference field to incident table. Change the table and field to those that's needed in your script.

Client Script

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

    var ajax = new GlideAjax('GetCallerUserNameFromIncident');
    ajax.addParam('sysparm_name', 'getUserName');
    ajax.addParam('sysparm_incident_id', newValue);
    ajax.getXMLAnswer(function(answer) {
        if (answer.length > 0) {
            g_form.setValue('username', answer);
        }
    });
}

Script Include:

var GetCallerUserNameFromIncident = Class.create();
GetCallerUserNameFromIncident.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getUserName: function() {
        var incident_id = this.getParameter('sysparm_incident_id');
        var grIncident = new GlideRecord('incident');
        if (grIncident.get(incident_id)) {
            var grUser = new GlideRecord('sys_user');
            if (grUser.get(grIncident.caller_id)) {
                return grUser.name;
            } else {
                return '';
            }
        } else {
            return '';
        }
    },
    type: 'GetCallerUserNameFromIncident'
});
