Hi @XYD23

Follow below steps :

Step 1 : Create client callable script include

Name : TechTaskUtils

var TechTaskUtils = Class.create();
TechTaskUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

   /* Function */
	getTechTaskDetails : function(){
	/*1. Declare & initialize necessary variables/JSON  */	
	var result = {
		'title' :'',
		'assigned_to' : '',
		'due_date' :''
	};
    
	/*2.Get newValue (sys_id) from client script */
	var getSysId = this.getParameter('sysparm_sysID');
    
	/*3. Glide record on your table */
	var grTech = new GlideRecord('u_tech_task');
	grTech.addQuery('sys_id',getSysId);
	grTech.query();
    
	if(grTech.next()){

		/*3.1 Set JSON object */
		result.title = grTech.getValue('u_title');
		result.assigned_to = grTech.getValue('u_assigned_to');
		result.due_date = grTech.getValue('u_due_date');
          
	}
   
   /*4.Stringify result & return it */
   return JSON.stringify(result);

	},

    type: 'TechTaskUtils'
});

Step 2 : Write onChange Client script

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

   /*1. Call Script include using GlideAjax */
   var ga = new GlideAjax('TechTaskUtils');  //script include name
   ga.addParam('sysparm_name','getTechTaskDetails');  //function name within script include
   ga.addParam('sysparm_sysID',newValue);   //pass the value to script incldue

   ga.getXMLAnswer(callBackFunction);

   function callBackFunction(answer){

	/* here we will get the result from script include & Parse the answer */
	var result = JSON.parse(answer);

	/* Set value on form */

	g_form.setValue('u_title',result.title);
	g_form.setValue('u_assigned_to',result.assigned_to);
	g_form.setValue('u_due_date',result.due_date);

   }
 
}

Hope this helps...!!!

Hi @XYD23

You can use GlideAjax or getReference method.

If you need data related with reference field then you can prefer getReference instead of GlideRecord.

Sharing how it can be done with getReference().

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   var techList =g_form.getReference('u_tech_list', callback); // name of your field
// below is callback function
   function callback(techList){
	g_form.setValue('u_title',techList.u_title);
	g_form.setValue('u_assigned_to',techList.u_assigned_to);
	g_form.setValue('u_due_date',techList.u_due_date);
   }
}
