我正在尝试动态创建网格。我的目标是创建一种动态前端来显示一些数据库表。因此,我需要动态添加/删除列。我需要动态更改列的数据类型

我使用了中提供的脚本作为答案

我构建了我的网格,它显示了我的列。但没有数据加载到网格中。Firebug显示请求被触发。返回正确的json数据。事实上,grid还触发gridComplete事件。但没有数据显示:-(

有人遇到过这个问题吗?我花了一整天的时间调整jsonReader和colModel,但都没有用

我的示例html文件:

在我看来,您似乎忘记了将{}作为
gridModel
的一个包含

{
    "JSON": "success",
    "colModel": [
       ...
    ],
"colNames": [ "UserInfo ID", "User ID" ],
"gridModel": [
        {"userID": "SMI","userInfoId": 5},
        {"userID": "ABC","userInfoId": 7},
        {"userID": "PQR","userInfoId": 8},
        {"userID": "FUR","userInfoId": 10},
        {"userID": "COO","userInfoId": 13}
    ],
    "page": 1,
    "records": 56,
    "rows": 15,
    "sidx": null,
    "sord": "asc",
    "total": 0
}
而不是

{
    "JSON": "success",
    "colModel": [
       ...
    ],
"colNames": [ "UserInfo ID", "User ID" ],
"gridModel": { [
        {"userID": "SMI","userInfoId": 5},
        {"userID": "ABC","userInfoId": 7},
        {"userID": "PQR","userInfoId": 8},
        {"userID": "FUR","userInfoId": 10},
        {"userID": "COO","userInfoId": 13}
    ],
    "page": 1,
    "records": 56,
    "rows": 15,
    "total": 0
  }
}
“jsonmap”
的使用似乎也不是我真正需要的。

非常感谢Oleg

在按照您的建议修改了json的结构,然后进行了一些调试以修复一些属性(如root)之后,我能够让它正常工作。下面是最终的json和html:

Html:

您非常接近..需要进一步更改..就像记录数组必须有一个正确的json名称一样。因此{“dataset”:[…],…}。我缺少的另一项是将repeatitem设置为false并提供右根属性。只需发送一个值数组并指定repeatitems:true,就可以进一步优化数据集(在jsonReader中)
