This is to change CSS, which is a little inflexible

I want to use this way

UniSession.AddJS('Ext.get("' + UgTreeMenu01.JSId + '").setStyle({"background-color": "rgba(0,0,0,0)"})'); 

But I can't get another level of jsid

As shown in the figure

Thank you very much for your answer

My problem has been solved,

The solution is to share with you:

UniSession.AddJS(' if(!!Ext.get("' + MenuTree.JSId + '").el.dom.children[0].id){'
                  +'      var kid = Ext.get("' + MenuTree.JSId + '").el.dom.children[0].id;'
                  +'      Ext.get(kid).setStyle({"background-color":"rgba(200,0,0,1)"});'
                  +' }');
