将数据源设置为 kendo 网格时获取错误消息 e.slice 不是函数

Question

我正在尝试获取数据并将该数据设置为使用 ajax 的 kendo 网格的数据源。

我正在从控制器正确获取数据。但是当我尝试将数据源设置为 kendo 网格时，它显示以下错误：

Uncaught TypeError: e.slice is not a function

$(function () {
        loadCstDetails();
    });

function loadCstDetails() {

        var statemenetInquiryParameter = {};

        statemenetInquiryParameter.isPrintZero = true;
        statemenetInquiryParameter.isPrintPayments = true;
        statemenetInquiryParameter.isPrintAdjust = true;
        statemenetInquiryParameter.cst_stmt_from = new Date("April 01, 2016");
        statemenetInquiryParameter.cst_stmt_to = new Date("April 12, 2016");
        statemenetInquiryParameter.customerCode = 007;

        $.ajax({
            type: 'POST',
            data: JSON.stringify({ statemenetInquiryParameter: statemenetInquiryParameter }),
            contentType: 'application/json;',
            dataType: 'json',
            url: '@Url.Action("LoadCustomerStatementEnquiryDetails", "Stage")',
            success: function (result) {
                $('#gridCustomerCstTranDetailsManual').data('kendoGrid').dataSource.data(result);
            }
        });

仅从提供的代码的目视检查来看，我怀疑我们这里有两件事。

首先：

.DataSource(dataSource => dataSource.Ajax())

如果您正在定义一个 "remote" 数据源，那么您需要为命令提供一个 read 操作或将其绑定到一个集合（根据我的经验）可能是导致您遇到的错误的原因。

除此之外，您似乎正在编写网格声明可以为您完成的代码。

如果您希望将一些参数发送到控制器，那么我建议您按如下方式更改您的代码：

    .DataSource(dataSource => {
                dataSource.Ajax()
                .Read(read => {
                 read.Action("LoadCustomerStatementEnquiryDetails", "Stage").Data("loadCstDetails");
                              })

然后将现有的 loadCstDetails 函数更改为：

function loadCstDetails() {

        var statemenetInquiryParameter = {};

        statemenetInquiryParameter.isPrintZero = true;
        statemenetInquiryParameter.isPrintPayments = true;
        statemenetInquiryParameter.isPrintAdjust = true;
        statemenetInquiryParameter.cst_stmt_from = new Date("April 01, 2016");
        statemenetInquiryParameter.cst_stmt_to = new Date("April 12, 2016");
        statemenetInquiryParameter.customerCode = 007;
   return {statemenetInquiryParameter: statemenetInquiryParameter};
}

这应该会像您原来那样传递对象。

希望这能为您提供可行的解决方案。

Answer 2

这个错误是由于使用ToDataSourceResult()造成的。尝试更新 LoadCustomerStatementEnquiryDetails() 方法，如下所示：

public JsonResult LoadCustomerStatementEnquiryDetails(StatemenetInquiryParameter statemenetInquiryParameter)
{
    List<CstTran> l = new List<CstTran>();

    for (int i = 0; i < 12; i++)
    {
        CstTran c = new CstTran();

        c.cst_inv_date = statemenetInquiryParameter.cst_stmt_from.AddDays(i);
        c.cst_type = "I";
        c.cst_ih_invno = i + 1;
        c.cst_dr_amount = i;
        c.cst_cr_amount = 0;
        c.cst_dr_balance = c.cst_dr_balance + i;

        l.Add(c);
    }
    return Json(l, JsonRequestBehavior.AllowGet);
}
