推荐答案

您可以应用样式:

yourFormPanel.getForm().findField("field_name").labelEl.setStyle({"color":"red"});

或添加/删除CSS类:

or add/remove css classes:

yourFormPanel.getForm().findField("field_name").labelEl.addCls("red-label");
yourFormPanel.getForm().findField("field_name").labelEl.removeCls("black-label");
