Hi,

you can use onChange client script + GlideAjax

OR

you can use onSubmit with GlideAjax and custom solution for synchronous ajax call

But remember these points:

1) Asynchronous GlideAjax won't work as by the time ajax function returns the value your form will get submitted

2) Synchronous GlideAjax is not allowed in portal and scoped application

Refer this link

Refer these links for workaround/solution on how to use Synchronous GlideAjax in onSubmit

HI,

please try below code:-

Script Include: It should be client callable

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

	checkRecordPresent: function(){
		var obj = {};
		var id = this.getParameter('sysparm_userID');            
		var gr = new GlideRecord('sys_user');
		gr.addQuery('sys_id', id); 
		gr.query();
		if(gr.next()){
			obj['email'] = gr.getValue('email');
			obj['manager'] = gr.getValue('manager');
			obj['location'] = gr.getValue('location');
			obj['region'] = gr.region.toString();
		}
		return JSON.stringify(obj);
	},
	type: 'CheckRecords'
});
onChange Client Script:

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

	var ga = new GlideAjax('CheckRecords');
	ga.addParam('sysparm_name', "checkRecordPresent");
	ga.addParam('sysparm_userID', g_form.getValue('requested_for_variable')); // give here your variable name
	ga.getXMLAnswer(function(answer){
		if(answer != 'not found'){
			var parser = JSON.parse(answer);
			g_form.setValue('manager_variable', parser.manager); // give here manager variable name
			g_form.setValue('email_variable', parser.email); // give here email variable name
			g_form.setValue('location_variable', parser.location); // give here location variable name
			g_form.setValue('region_variable', parser.region); // give here region variable name
		}
	});
	//Type appropriate comment here, and begin script below

}

Hope this helps.
