Autopopulating the two list collectors

[ServiceNow Use6]

Hi,

I have a scenario where i have two catalog variables, Servers and Applications. Servers is pointing to cmdb_ci_server, while applications pointing to the cmdb_ci_appl tables. Servers selection should autopopulate the Applications. it is autopopulating for 1 selection, but when i select multiple Servers, it is not working. Please make it as simple as possible. Kindly help.

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

   var gr = new GlideAjax('cmdbServer');
   gr.addParam('sysparm_name', 'cmdbFunction');
   gr.addParam('sysparm_id', newValue);
   gr.getXML(callBackFunction);
   function callBackFunction(response){
	var answer = response.responseXML.documentElement.getAttribute('answer');	
	g_form.setValue('application', answer);
   }
   
}

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

    cmdbFunction: function() {
        var abc = this.getParameter('sysparm_id');
		var gr = new GlideRecord('cmdb_rel_ci');
		gr.addQuery('parent', abc);
		gr.addQuery('type.name', 'Runs on::Runs');
		gr.query();
		while(gr.next()){
			return gr.child.name;
		}
    },

    type: 'cmdbServer'
});

Hi @ServiceNow Use6 

Update your script include script as below. The one you have written works only for one server and moreover, you need to get child CI sys_ids instead of name of the CI.

 cmdbFunction: function() {
var childCIs = [];
        var abc = this.getParameter('sysparm_id');
		var gr = new GlideRecord('cmdb_rel_ci');
		gr.addQuery('parent', 'IN', abc);
		gr.addQuery('type.name', 'Runs on::Runs');
		gr.query();
		while(gr.next()){
			childCIs.push(gr.child.toString());
		}
return childCIs.join(',');
    },

Hope your variables are list collector. Modify your script include as below

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

    cmdbFunction: function() {
        var abc = this.getParameter('sysparm_id');
	var gr = new GlideRecord('cmdb_rel_ci');
	gr.addQuery('parent.sys_id', 'IN', abc);
	gr.addQuery('type.name', 'Runs on::Runs');
	gr.query();
	var returnArr = [];
	while(gr.next()){
		returnArr.push(gr.child.name.toString());
	}
	return returnArr.join(",");
    },

    type: 'cmdbServer'
});

Hi,

It works perfectly. is it possible for us to make the script more easier? I am not that good with scripting.
