UI Page using GlideAjax in Client returning null

[brian4500]

Hello,

First time posting here and new to ServiceNow! My issue is with my UI Page's Client Script/Script Include returning a null answer for the value.

The basic goal of the code is to change an HTML button red/amber/green based on if the query is hitting true. I'm trying to return true/false and test that inside the client, essentially making the server do the heavy lifting of running the queries and then testing the results it pushes back. The code I have posted here is for the red color change condition only.  

Client Script in UI Page

$ = jQuery.noConflict(true);
$( document ).ready(function() {
     //Type appropriate comment here, and begin script below
var a = new GlideAjax('TOER_color_change');
a.addParam('sysparam_name','redColor'); //calling the function in the client script
a.getXMLAnswer(red_color_check);
console.log('run');
function red_color_check(response)
{
var answer = response;
console.log('r_answer: '+answer);
if(answer == true)
$('#VNTV').css('background-color','red');
}
});

Script Include

var TOER_color_change = Class.create();
TOER_color_change.prototype = Object.extendsObject(AbstractAjaxProcessor, {
redColor:function()
{
var rd = new GlideRecord('u_bcm_incident');
rd.addEncodedQuery('active=true^priorityIN1,2^u_caused_by=1');
rd.query();
var r_result = false;
if(rd.next())
r_result =   true;
return   r_result;
},
type: 'TOER_color_change'
});

When I console log ["r_answer: " +result] it gives me null every time. I've read through quiet a few threads on here including this one which was similar but I'm still getting null!

Here is the code a little easier to read:

Client Script in UI Page

$ = jQuery.noConflict(true);
$( document ).ready(function() {
     //Type appropriate comment here, and begin script below
var a = new GlideAjax('TOER_color_change');
a.addParam('sysparam_name','redColor'); //calling the function in the client script
a.getXMLAnswer(red_color_check);
console.log('run');

function red_color_check(response)
{
var answer = response;
console.log('r_answer: '+answer);
if(answer == true)
$('#VNTV').css('background-color','red');
}

});

Script Include

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

redColor:function()
{
var rd = new GlideRecord('u_bcm_incident');
rd.addEncodedQuery('active=true^priorityIN1,2^u_caused_by=1');
rd.query();
var r_result = false;
if(rd.next())
r_result =   true;
return   r_result;
},

type: 'TOER_color_change'
});

You can directly call script include inside the function than querying in script section

[brian4500]

Are you talking about calling the script include inside of the function red_color_check?
