extjs form textfield的隐藏方法

this.formpanel = new Ext.FormPanel（{
items: [{
fieldLabel: "代码",
name: "FCode",
anchor:"100%",
id: "fid"
},{
fieldLabel: "名称",
name: "FName",
anchor:"100%" // anchor width by percentage
},{
xtype: "textfield",
name: "FID",
id: "FID",
hidden: true,
hideLabel:true
}]
}）;
只需将textfield的hidden和hideLabel配置为true就可以了。只设置hidden:true时会显示出来一个：的标签。
