Extjs calling class of an object

Example: In JQuery we call

var par = $('#container');
console.log($('.subcontainer', par).length);

In EXTJS how do we do that?

var par = Ext.get('container'); // Is the prepare parent object.

But Ext.select('.subcontainer', par).length isn't working

Help me out in calling a class from an object using EXTJS.

Thanks in advance.

select returns a collection class: http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.dom.CompositeElementLite

You want to call the getCount method.

A better way to call it would be:

var items = Ext.get('container').select('.subcontainer');
