AbstractAjaxProcessor undefined, maybe missing global qualifier

[Ebe]

Hi Team,

I am developing a custom application in my personal dev instance. I am trying to invoke script include in client script and while doing I am facing AbstractAjaxProcessor error. I have verified API name to match in both the scripts and to call right function name. 

Client Script

function onSubmit(){
	if (g_form.getValue('first_name') == '' || g_form.getValue('last_name') == ''){
		g_form.addErrorMessage('First and Last name cannot be empty!');
		return false;
	}	
	
	var ga = new GlideAjax('SZAPICall');
	ga.addParam('sysparm_name','loadData');
	ga.addParam('sysparm_first_name',g_form.getValue('first_name'));
	ga.addParam('sysparm_last_name',g_form.getValue('last_name'));
	alert('before getXML');
	ga.getXML(JSONParse);
	alert('after getXML');
	function JSONParse(response) {
     var answer = response.responseXML.documentElement.getAttribute("answer");
     alert(answer);
	}
}

Scirpt Include

var SZAPICall= Class.create();
SZAPICall.prototype = Object.extendsObject(AbstractAjaxProcessor,{
	loadData:function(){
		alert('inside script include');
		return this.getParameter('sysparm_first_name')+"|"+this.getParameter('sysparm_last_name');
},
    type: 'SZAPICall',
	isPublic: true
});

I am getting below error upon form submission

Can someone please let me know what is going wrong in this approach?

Thanks

You are missing a "global" prefix.
When extending a global Script Include from a Scoped Script, you must prefix with global.

SZAPICall.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

Thanks Paul, I didn't know about this. This fixed the error, however loadData function is not called. Is there a different way to call this function from scoped to global script?

You don't need alert in script include (server side code).

alert('inside script include');

True, I have removed it and now I see the script include code got executed. Thanks guys!
