Why can't I access method in Script Include

[dalton1]

Hi,

I have a script include and catalog client script that instantiates and access the script include. Problem is, it does not return the value.

Script Include

==========

var acn_catalogClientScripts = Class.create();

acn_catalogClientScripts.prototype = {

      initialize: function() {

            this.errorMessage = "";

      },

  sampleFunction: function(){

  return "SampleAnswer!";

  },

      type: 'acn_catalogClientScripts'

};

Catalog client script

=================

var validation = new gacn_catalogClientScripts();

var validation_result = validation.sampleFunction();

g_form.addErrorMessage("Value is " + validation_result);

validation_result does not return anything. Please help. Do I really have to use GlidAjax for this? As per my understanding, accessing script include can be done this way.

Now I am enlightened. Server to server only. Thanks Gurpreet Singh!

Hi Gurpreet Singh,

I tried using GlideAjax but it still does not return anything.

function onLoad() {

  g_form.clearMessages();

  var validation = new GlideAjax('acn_catalogClientScripts');

  validation.addParam("sysparm_name","sampleFunction");

  validation.getXMLWait();

  g_form.addErrorMessage("Answer is" + validation.getAnswer());

}

It seems validation.getAnswer() does not return anything.

change statement g_form.addErrorMessage("Answer is" + validation.getAnswer()); with

alert("Answer is" + validation.getAnswer())

Also share the script include in not working

Hi Gurpreet Singh,

Below is my updated codes:

Script include

=====================

var acn_catalogClientScripts = Class.create();

acn_catalogClientScripts.prototype = Object.extendsObject(AbstractAjaxProcessor, {

      initialize: function() {

            this.errorMessage = "";

      },

  sampleFunction: function(){

  return "SampleAnswer!";

  },

      type: 'acn_catalogClientScripts'

});

Catalog Client Script

=====================

function onLoad() {

  g_form.clearMessages();

  var validation = new GlideAjax('acn_catalogClientScripts');

  validation.addParam("sysparm_name","sampleFunction");

  validation.getXMLWait();

  alert("Answer is " + validation.getAnswer());

}

Output

===========

"Answer is null"

Why is the answer null when I have returned a pre-defined string?

Code is working fine .. make sure that client callable acheck box is checked for script include .
