text : "允许登录",
winth : 150,
editor: {
     xtype: 'checkbox',
     cls:'x-grid-checkheader-editor'
     }
} ];
我的json数据有值：
{"total":2,"data":[{"createdDateTime":"2013-10-31T00:00:00","email":"[email protected]","id":6,"isApproved":"true","lastLoginDateTime":"2013-11-01T00:00:00","password":"123","roles":"系統管理者","userName":"admin"},{"createdDateTime":"2013-10-30T00:00:00","email":"[email protected]","id":8,"isApproved":"true","lastLoginDateTime":"2013-11-01T00:00:00","password":"456","roles":"普通用戶","userName":"user"}],"success":true}但是前台不显示页面。
如果json的数据是：
[{"createdDateTime":"2013-10-31T00:00:00","email":"[email protected]","id":6,"isApproved":"true","lastLoginDateTime":"2013-11-01T00:00:00","password":"123","roles":"系統管理者","userName":"admin"},{"createdDateTime":"2013-10-30T00:00:00","email":"[email protected]","id":8,"isApproved":"true","lastLoginDateTime":"2013-11-01T00:00:00","password":"456","roles":"普通用戶","userName":"user"}]
就能正常显示。extgridpaneljson
