DataTables 警告：请求第 0 行的未知参数“pCodigo”

Question

我试图在单击按钮时填充表格，从 ASP.NET ApiController 获取数据。我已经尝试过几乎所有在 SO 中针对其他类似问题发布的解决方案，但总是会出现该错误。 希望有人看到这个问题。

html 标记：

<input type="button" ID="btnSearch" name="btnSearch" class="btn btn-success" value="Buscar" />
<table id="ResultsTable" class="table table-bordered table-condensed" style="font-size: 11px;">
<thead>
    <tr>
        <th><%=GetLiteral("Codigo")%></th>
        <th><%=GetLiteral("Descripcion")%></th>
        <th><%=GetLiteral("Marca")%></th>
        <th><%=GetLiteral("IC")%></th>
        <th><%=GetLiteral("IV")%></th>
        <th><%=GetLiteral("Tarifa")%></th>
        <th><%=GetLiteral("Precio")%></th>
        <th><%=GetLiteral("P")%></th>
        <th><%=GetLiteral("Total")%></th>
        <th><%=GetLiteral("Central")%></th>
        <th><%=GetLiteral("Centro")%></th>
    </tr>
</thead>
<tbody>
</tbody>

JS：

$(document).ready(function () {
    var SearchTable = $("#ResultsTable").DataTable({
        columns: [
            { data: "pCodigo" },
            { data: "rDescripcion" },
            { data: "rMarca" },
            { data: "xIndiceCarga" },
            { data: "xIndiceVelocidad" },
            { data: "TARIFA" },
            { data: "PRECIO" },
            { data: "PROVIENE" },
            { data: "TOTAL" },
            { data: "CENTRAL" },
            { data: "CENTRO" }
        ],
        ordering: false,
        searching: false
    });

    $("#btnSearch").click(function () {
        var searchText = $("#<%=txtSearch.ClientID%>").val();
        $.ajax({
            type: "GET",
            contentType: "application/json; charset=utf-8",
            url: '<%=ResolveUrl("~/api/ProductSearch/")%>' + searchText + '/0138107',
            dataType: "json"
        }).success(function(result) {
            SearchTable.clear().draw();
            SearchTable.rows.add(result).draw();
        }).fail(function(jqXHR, textStatus, errorThrown) {
            alert("FAIL: " + textStatus + " = " + errorThrown);
        });
    });
}

数据样本：

注意：html 标记中的 GetLiteral 函数返回一个列名国际化的字符串，该字符串可能与显示的文本和列名不同。我认为这不是问题。 提前致谢！

您必须插入Table 数组：

}).success(function(result) {
   SearchTable.clear().draw();
   SearchTable.rows.add(result[0].Table).draw();
})

或者，您可以循环遍历 Table 数组并单独添加每个项目：

}).success(function(result) {
   SearchTable.clear().draw();
   for (var i=0;i<result.Table.length;i++) {
      SearchTable.row.add(result[0].Table[i]).draw();
   }
})
