Title Body

I have a component as follow : { xtype: 'fieldcontainer', layout: 'hbox', id: 'article-level-container', defaultType: 'textfield', fieldDefaults: { labelAlign: 'top' }, items: [{ fieldLabel: 'LEVEL', name: 'artLevel', inputWidth: 216, margins: '0 5 5 0', allowBlank: false, fieldStyle: 'text-align: right; font-size: 13pt; background-color: #EAFFCC;' }, { fieldLabel: 'VALUE', name: 'artValue', inputWidth: 216, allowBlank: false, blankText: 'zorunlu alan, boş bırakılamaz', fieldStyle: 'text-align: right; font-size: 13pt; background-color: #EAFFCC;', listeners: { change: function(textfield, newValue, oldValue) { if (oldValue == 'undefined' || newValue == '') { Ext.getCmp('btnArticleSave').disable(); } else { Ext.getCmp('btnArticleSave').enable(); } } } }] } I want to get second item fieldLabel value ( in this case VALUE ). How can I get this field value outside the onReady function? How can I change this field label with new value ( I want to change fieldlabel with selected combobox value ) UPDATE I tried the following : var artField = Ext.ComponentQuery.query('#articleValueField'); console.log(artField);
