Client script gets null answer from script include

[Beata I_owiecka]

Hi, I'm learning servicenow and javascript and trying to create a client script which is setting 'company' filed to a caller's company. Unfortunately I can't get it right. "Answer" variable in client script is null.

this is my client script Set User Company (which is calling my Script Include - UserCompany)

Set User Company (client script)

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    var ga = new GlideAjax('UserCompany');   
    ga.addParam('sysparm_name', 'getUserCompany');   
    ga.addParam('sysparm_user_id', newValue);   
    ga.getXMLAnswer(analyze);
}

function analyze(answer) {  
    alert("answer: " + answer);
    g_form.setValue('company', answer);
    g_form.setReadOnly('company', true);
} 

UserCompany (script include)

var UserCompany = Class.create();
UserCompany.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    initialize: function() {
    },
	
	getUserCompany: function() {
		var userRecord = new GlideRecord('sys_user');
		var user_id = this.getParameter('sysparm_user_id');
		userRecord.get('sys_id', user_id);
		
		var companyId = userRecord.getValue('company');
		var companyRecord = new GlideRecord('core_company');
		companyRecord.get('sys_id', companyId);
		return companyRecord.name.getDisplayValue();
	},

    type: 'UserCompany'
});

But when I try to test my script include from "scripts- background" using this script, its working, I get proper company name, so the problem must be somewhere in the client script, but I can't find it!

var company = new UserCompany().getUserCompany();
gs.info(JSON.stringify(company));

I'm also modifying a little my script include for testing (to be able to get any user record):

var UserCompany = Class.create();
UserCompany.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    initialize: function() {
    },
	
	getUserCompany: function() {
		var userRecord = new GlideRecord('sys_user');
// hardcoded user id
		var id = '46d44a23a9fe19810012d100cca80666';
		userRecord.get('sys_id', id);
		
		var companyId = userRecord.getValue('company');
		gs.info("companyId: " + companyId);
		var companyRecord = new GlideRecord('core_company');
		companyRecord.get('sys_id', companyId);
		return companyRecord.name.getDisplayValue();
	},

    type: 'UserCompany'
});

I was also looking for some conflicting UI policies or client scripts, but I couldn't find any.

Can anyone help, please ? 🙂

Hi,

update as this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	var ga = new GlideAjax('UserCompany');   
	ga.addParam('sysparm_name', 'getUserCompany');   
	ga.addParam('sysparm_user_id', newValue);   
	ga.getXMLAnswer(function(answer){
		alert("answer: " + answer);
		g_form.setValue('company', answer);
		g_form.setReadOnly('company', true);
	});

}

Remove initialize() function and update as this

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

	getUserCompany: function() {
		var userRecord = new GlideRecord('sys_user');
		var user_id = this.getParameter('sysparm_user_id');
		userRecord.get(user_id);
		var companyName = userRecord.company.getDisplayValue();
		return companyName;
	},

	type: 'UserCompany'
});

Thank you, almost working 🙂 Don't know why this doesn't work:

g_form.setReadOnly('company', true);

 Field is still editable.

Hi,

Glad to know.

use this

g_form.setReadonly('company', true)

Hi,

are you sure no other script is making the field editable?

is the field getting populated with company name?

this looks good to me.

g_form.setReadOnly('company', true)
