Question

在我的MVC项目中，我已经实现了JQuery数据表来检索数据。我正在使用1.9.4 jquery.dataTables.js。我有三个过滤器来限制表中的输出。其中两个完美无缺。然而，在第三个选项，假设显示所有记录，我收到“未定义”弹出警报。我在IE和Google Chrome中都试过了。

    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.Title = "Call log";
}

好的，请考虑jquery dataTable实例化的以下对象：

var conf = {
   columnDefs : [ { className : '...' }, targets : { 3, 6, 7} ],
   columns: [
     [ title : 'product id' ],
     [ title : 'product name' ]
   ],
   data : [
     [ 23, "Cellular" ] // nested array, pay attention to the number of values added, 2 values, by order: productId, productName
   ],
   order: [[0,'desc']], // first column set to desc, add a new value in the array to apply multi-order, values order matters!!
   destroy : !0,
   pageLength : 10,
   paging : !0,  // full number pagination is set as default
   responsive : !0,
   bSort : !0,
   bSortable : !0,
   bFilter : !1,
   autoWidth : !1
};

正如您所看到的，只是对象定义了一个表，显然有2列'productId'，'productName';调整它以适合您的情况，这将是向列数组添加值的问题，您想要添加到列的任何额外配置，您必须将它添加到columnDefs（columnDefinitions的缩写）。

请记住，如果数据集与列不匹配，您将继续收到类似于报告的错误。确保数据数组中的每个嵌套数组具有与列相同的值数，请阅读注释以获取更多详细信息。如果由于任何原因，您的数据与该订单不匹配，您将不得不手动更改该订单，强制使用“ - ”或“n / a”值的空值，以便所有嵌套数组具有相同的逻辑值。

我希望这会有所帮助。祝你好运。
