我正在尝试使用 YUI DataTable 显示以下 JSON 对象。我能够在 YUI DataTable 中成功显示 lastName、firstName、startDate、employeeCode、employeeStatus。但我无法显示内部对象中的值。在列集中,我尝试了user.userId,它在 DataTable 中显示为{value}

[    
{
            "lastName": "MyLastName",
            "firstName": "MyFirstName",
            "startDate": "11-11-11",
            "employeeCode": "124",
            "employeeStatus": "Permanent",
            "user": {
                "key": {
                    "name": null,
                    "parent": {
                        "name": null,
                        "parent": null,
                        "id": 855,
                        "namespace": "",
                        "complete": true,
                        "kind": "Employee"
                    },
                    "id": 856,
                    "namespace": "",
                    "complete": true,
                    "kind": "Users"
                },
                "salt": null,
                "userId": "myemail@example.com",
                "status": true,
},
{
...
}
]

这是Javascript代码:

<script type="text/javascript">
YUI().use("jsonp", 'sortable', 'json-parse', 'datatable', "datatable-sort", "io", "node", function(Y) {
var nestedCols = [ 
    {key : "employeeCode",label : "Employee Code", sortable:true},
    {key : "firstName", label : "First Name",sortable: true},
    {key : "lastName", label : "Last Name", sortable:true},
    {key : "user.userId", label : "Email Id"},
    ];
Y.io('/Employee/AjaxList', {
on : {
success : function(tx, r) {
var data = Y.JSON.parse(r.responseText);
var table = new Y.DataTable.Base({
        columnset : nestedCols,
        recordset : data,
        }).plug(Y.Plugin.DataTableSort);
        table.render("#empTable");
}
}
});
});
</script>

这个代码片段有什么问题吗?如何在 DataTable 中显示 user.userId 的值?

注意:JSON 是使用 Jackson 生成的,应用程序是在 GAE/J 中开发的


更新:

我按照@Luke 的建议使用了DataSource。这次我得到了一个只有标题的空 DataTable。这是代码片段。

YUI().use("datasource-get", "datatable-base", "datatable-datasource","datasource-arrayschema", function (Y) {

var url = "/Employee/AjaxList?";
var dataSource, table;

dataSource = new Y.DataSource.Get({ source: url });

dataSource.plug(Y.Plugin.DataSourceArraySchema, {
        schema: {
                resultFields: ["firstName", "lastName"]
                }
        });

var cols = ["firstName", "lastName"];

table = new Y.DataTable.Base({
                columnset: cols,
});

table.plug(Y.Plugin.DataTableDataSource, { datasource: dataSource });

table.render("#empTable");

table.datasource.load();
});

您需要使用 datasource-jsonschema 来解析嵌套值。看这个例子:http: //yuilibrary.com/yui/docs/datatable/datatable-dsget.html

您应该能够按照这些步骤操作,将 Y.DataSource.Get 替换为 Y.DataSource.IO

我在论坛发帖后从 YUI 论坛获得了解决方案:http: //yuilibrary.com/forum/viewtopic.php ?f=92&t=8685

这是对我有用的代码:

YUI().use( "datasource-io", "datasource-jsonschema", "datatable-base", "datatable-datasource", "datatable-scroll", 
           function (Y) {
    var cols = [    
            { key: "name", label: 'Name'  }, 
            { key: "email",  label: "Email"  },
            { key: "user.username", label: 'Username'  },
            { key: "user.password", label: 'Password'  },
        ];
    car url = "/Employee/AjaxList";
    var ds = new Y.DataSource.IO( { 
        source:url
     });
     ds.plug(Y.Plugin.DataSourceJSONSchema, {
            schema: {
                resultFields: [ 'name', 'email', 'user.username', 'user.password' ],
            }
        });
    var dt = new Y.DataTable.Base({
        columnset:cols } )
        .plug(Y.Plugin.DataTableDataSource, {datasource:ds});
    dt.render("#dtable");
    dt.datasource.load();
});

希望这可以帮助其他正在努力使用 DataTable 和 DataSource 的人。
