getting null value in client script

[Community Alums]

I am checking unique CI Group in table cmdb_ci_group and always getting null

wrote onchange catalog client script on variable level_1_organization and client callable SI

Here is the code

Client script:

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

    var level1Org = g_form.getValue('level_1_organization');

    if (level1Org) {
        var ga = new GlideAjax('CheckChildDepartment');
        ga.addParam('sysparm_name', 'getChildDepCIGroup');
        ga.addParam('sysparm_level1_org', level1Org);
        ga.getXML(childDepartmentParse);

        //ga.getXMLAnswer(function(answer){

        function childDepartmentParse(response) {

            var answer = response.responseXML.documentElement.getAttribute("answer");
            alert(answer);
            if (answer == 'true') {
                g_form.setMandatory('level_2_organization', true);
            } else {
                g_form.setMandatory('level_2_organization', false);
            }

        }
    }
}

 Script Include: checked in background script gives correct output

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

    getChildDepCIGroup: function() {
        var level1Org = this.getParameter('sysparm_level1_org');
        // var result = '';
        //  var level10rg = 'bf1043f5db05f3c0105f3e0439961968';
        if (level10rg) {

            var grlevel1 = new GlideRecord("cmn_department");
            grlevel1.addQuery("sys_id", level10rg);
            grlevel1.query();
            if (grlevel1.next()) {
                var correlationID = grlevel1.correlation_id.toString();
                var grlevel2 = new GlideRecord("cmn_department");
                grlevel2.addEncodedQuery('u_active=true^correlation_idISNOTEMPTY');
                grlevel2.addEncodedQuery('parent.correlation_id=' + correlationID);
                grlevel2.query();
                var sysIdArray = []; // Array to store sys_ids   
                while (grlevel2.next()) {
                    sysIdArray.push(grlevel2.sys_id.toString());
                }
                // gs.print('total L1 department: ' + grlevel2.getRowCount());
                // gs.print('L1 department sysIdArray: ' + sysIdArray);
                if (sysIdArray.length > 1) {

                                uniqueArray.push(array[i]);
                            }
                        }
                        return uniqueArray;
                    }

                    ciGroupUniqueArray = getUnique(ciGroupArray); //storing Unique cmdb_ci_group sys_ids in array

                    if (ciGroupUniqueArray.length > 1) {

So after adding logs in script include what's your analysis?

Is the function getting called? till which place script is working fine and printing logs?

[Community Alums]

Hi @Ankur Bawiskar , Script include gives result = true, means it is working fine

result = 'true';

[Community Alums]

Hi @Ankur Bawiskar ,

On background script I used result variable to store return value. It gives below output.

try to use getXMLAnswer()

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

	var level1Org = g_form.getValue('level_1_organization');

	if (level1Org) {
		var ga = new GlideAjax('CheckChildDepartment');
		ga.addParam('sysparm_name', 'getChildDepCIGroup');
		ga.addParam('sysparm_level1_org', level1Org);
		ga.getXMLAnswer(function(answer){
                        alert(answer);
			if (answer.toString() == 'true') {
				g_form.setMandatory('level_2_organization', true);
			} else {
				g_form.setMandatory('level_2_organization', false);
			}
		});
	}
}
