Ext之comboBox 本地数据字典

//车辆状态（值固定，写在前台页面，不用后台数据字典）var carState = new Ext.form.ComboBox({    hiddenName:'car.status',    allowBlank:false,      width : 165,      editable:false,      fieldLabel:'<font color="red">*</font>车辆状态',      triggerAction: 'all',      lazyRender:true,      mode: 'local',      store: new Ext.data.ArrayStore({          fields: [              'idValue',              'displayText'          ],          data: [['0', '停用'], ['1','启用']]      }),      valueField: 'idValue',      displayField: 'displayText'  });
