Script Include and Client Script using glideajax

[JuliaHowells]

I have a variable in a variable set that shows all users by default and they do not want to change that, but on an order guide and the catalog items under that order guide, they want that user field to only show active users.

Script Include

var FilterUserResultstoActive = Class.create();

FilterUserResultstoActive.prototype = {
    initialize: function() {},

    activeUsers: function() {
        var userCheck = new GlideRecord("sys_user");
        userCheck.addEncodedQuery('active=true');
        userCheck.query();
    },

    type: 'FilterUserResultstoActive'
};

And then onload client script:

function onLoad() {
    //Type appropriate comment here, and begin script below
    var ga = new GlideAjax('FilterUserResultstoActive');
    ga.addParam('sysparm_name', 'FilterUserResultstoActive');
    ga.getXML(FilterUserResultstoActive);

    function FilterUserResultstoActive(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");

    }

}

But the filter isn't working. Any ideas on what I am missing?

@JuliaHowells Instead of writing the client script, you should use a reference qualifier in this case. For more information please refer to https://docs.servicenow.com/bundle/vancouver-platform-administration/page/script/server-scripting/co...

Sharing this live example demo where I added a resuable class and made the AbastractAjaxProcessor become a base class to dynamically call parameters that can revceive any type of class, function and payload from the client towards the server side using GlideAjax.
