Question

我正在尝试使用带有JSON返回数据的YUI创建数据表。

包含json返回的数据，并显示页面数据。

JSON数据：

[{"supplier_id":"127","name":"Adams Farms","description":"","ofarm":"1","active":"1"},{"supplier_id":"141","name":"Barriger Farms","description":"","ofarm":"1","active":"1"}]

YUI的Javascript：

<script type="text/javascript">
YAHOO.util.Event.addListener(window, "load", function() {
    YAHOO.example.JSON = function() {
        var myColumnDefs = [
            {key:"supplier_id", label:"ID"},
            {key:"name", label:"Name"},
            {key:"description", label:"Notes"},
            {key:"ofarm", label:"Ofarm"},
            {key:"active", label:"Active"}
        ];

        var myDataSource = new YAHOO.util.DataSource("ajax/select/supplier");
        myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;
        myDataSource.responseSchema = {
            fields: ["supplier_id","name","description","ofarm","active"]
        };

        var myDataTable = new YAHOO.widget.DataTable("json", myColumnDefs,
                myDataSource);

        return {
            oDS: myDataSource,
            oDT: myDataTable
        };
    }();
});
</script>

YUI测试（标题）

此示例使用数据填充DataTable。 （介绍文字）

ID - 名称 - 备注 - Ofarm - 活动（列标题）

数据错误。 （返回数据）

根据YUI dataSource页面，YUI dataSource预测了一个JavaScript对象，而不是一个对象数组。使用JSON时，必须在responseSchema属性上设置 resultsList 。某事（注意 dataSourceSettings.responseSchema.fields属性）

(function() {
    var YdataTable  = YAHOO.widget.DataTable,
        YdataSource = YAHOO.util.DataSource;

    var settings = {
        container:"<DATATABLE_CONTAINER_GOES_HERE>",
        source:"<URL_TO_RETRIEVE_YOUR_DATA>",
        columnSettings:[
            {key:"supplier_id", label:"ID"},
            {key:"name", label:"Name"},
            {key:"description", label:"Notes"},
            {key:"ofarm", label:"Ofarm"},
            {key:"active", label:"Active"}
        ],
        dataSourceSettings:{
            responseType:YdataSource.TYPE_JSON,
            responseSchema:{
                resultsList:"<DOT_NOTATION_LOCATION_TO_RESULTS>",
                fields:[
                    {key:"supplier_id"},
                    {key:"name"},
                    {key:"description"},
                    {key:"ofarm"},
                    {key:"active"}
                ]
            }
        },
        dataTableSettings:{
            initialLoad:false
        }
    }

    var dataTable = new YdataTable(
                    settings.container, 
                    settings.columnSettings, 
                    new YdataSource(
                    settings.source, 
                    settings.dataSourceSettings), 
                    settings.dataTableSettings);
})();

作为旁注，我在YUI数据表中查找“数据错误”的原因时找到了此页面，我最终发现我错过了/build/connection/connection-min.js脚本参考我的网页。

YUI数据表 - “数据错误”。
