When using GlideAjax I have to always look up the example on the wiki. One thing that I’ve learned is if you create a initialize function, it will break the client-callable script include.

Every GlideAjax call has at least two components required. The script include and the client side script.

Below I’ll put down a simple example of how I start up on these things.

Script Include

var SomeUtil = Class.create();
SomeUtil.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    // If you want to use initialize you can only if you include
    // AbstractAjaxProcessor with something like this;
    initialize: function(request, responseXML, gc) {, request, responseXML, gc);
        // Your code
    awesomeFunction: function(){
        var inputObj = JSON.parse(this.getParameter('sysparm_obj'));
        var returnObj = {
            input: inputObj
        return JSON.stringify(returnObj);
    type: 'SomeUtil'

Client Script

var ga = new GlideAjax('global.SomeUtil');
ga.addParam('sysparm_name', 'awesomeFunction');
ga.addParam('sysparm_obj', JSON.stringify({"hoo":"raa"}));
    var responseDocument = response.responseXML.documentElement;
    var answer = responseDocument.getAttribute('answer');
    var serverObj = JSON.parse(answer);

Note It seems that if you use the function name of getName it fails to return, so avoid that name I guess.
