Catalog Item Script Problem

[Tomas Linde]

Good morning everyone,
I have created a Catalog Client Script and an Include Script so that a user that contains the keyword "Manager" in its firstname and/or lastname cannot be selected in a variable of type reference and displays a message in case an attempt is made to select .
The fact is that it is not executed correctly and I cannot find the error, I would appreciate your help, greetings.

* Catalog Client Script: 

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading) {
    return;
  }

  var requestedFor = g_form.getValue('for_whom_are_you_requesting_this_item');

  var ga = new GlideAjax('ALOCatalogItemOtherSoftwareAJAX');
  ga.addParam('sysparm_name', 'isManager');
  ga.addParam('sysparm_user', requestedFor);

  ga.getXML(checkManager);
}

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

  if (isManager == 'true') {
    g_form.showFieldMsg('for_whom_are_you_requesting_this_item', 'The user is not allowed.', 'error');
  } else {
    g_form.clearFieldMsg('for_whom_are_you_requesting_this_item');
  }
}

* Script Include:

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

	isManager: function() {
		var userSysId = this.parameter ('sysparm_user');
        var gr = new GlideRecord('sys_user');
        if (gr.get(userSysId)) {
            return (gr.getValue('firstname').toLowerCase().indexOf('manager') !== -1 ||
                    gr.getValue('lastname').toLowerCase().indexOf('manager') !== -1);
        }
        return false;
    },

    type: 'ALOCatalogItemOtherSoftwareAJAX'
});

Hi @Tomas Linde, Can you try var userSysId = this.getParameter('sysparm_user'); instead of this.parameter? Also, the issue with the field names of first_name and last_name in the script include and make sure the Client Callable is checked on the script include.

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

	isManager: function() {
		var userSysId = this.getParameter('sysparm_user');
        var gr = new GlideRecord('sys_user');
        if (gr.get(userSysId)) {
            return (gr.getValue('first_name').toLowerCase().indexOf('manager') !== -1 ||
                    gr.getValue('last_name').toLowerCase().indexOf('manager') !== -1);
        }
        return false;
    },

    type: 'ALOCatalogItemOtherSoftwareAJAX'
});

Client script:

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading) {
    return;
  }
  var ga = new GlideAjax('ALOCatalogItemOtherSoftwareAJAX');
  ga.addParam('sysparm_name', 'isManager');
  ga.addParam('sysparm_user', newValue);
  ga.getXML(checkManager);
}

function checkManager(response) {
  var isManager = response.responseXML.documentElement.getAttribute("answer");
  if (isManager) {
    g_form.showFieldMsg('for_whom_are_you_requesting_this_item', 'The user is not allowed.', 'error');
  } else {
    g_form.clearFieldMsg('for_whom_are_you_requesting_this_item');
  }
}

Thanks,
Sunil
