How to pass an array of values from Script Include to Catalog Client Script?

[User205031]

Hi All,

We have a requirement. If a user selects an Application from 'app_service' then tags related to that application will populate in a different field. So, if an application has 3 tags, how to populate those 3 tags? If an application has 1 tag, it is populating fine but problem is with more than 1 tag. 

Catalog Client Script:

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

//Type appropriate comment here, and begin script below

var a = g_form.getValue('app_service');
alert(a);

var ga = new GlideAjax("TagPop");
ga.addParam("sysparm_name", "getTagName");
ga.addParam("sysparm_groupid", a);
ga.getXML(setTagName);

function setTagName(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
g_form.clearValue('subscription_name');
g_form.clearOptions('subscription_name');

alert(answer);

g_form.setValue('subscription_name', answer);
}
}

Script Include:

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

getTagName: function() {
var efg = '';
var nam = this.getParameter('sysparm_groupid');
//gs.log('h1' + nam);
//var t = nam.getDisplayValue();
//gs.log('h2' + t);
var abc = new GlideRecord('label_entry');
abc.addQuery('title', 'CONTAINS', nam);
//var vendors = [];
abc.query();
if (abc.next()) {
efg = abc.label.getDisplayValue();
//vendors.push(efg.getUniqueValue());
}
return efg;
//return 'sys_idIN'+vendors.toString();
},

type: 'TagPop'

});

Please help!

In the catalog client script in Patryk's example use

var answer = JSON.parse(answer);

var tagPop = answer.split(',');
