Question

我正在尝试使用ajax获取数据并将该数据设置为kendo网格的数据源。

我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，它会向我显示以下错误：

未捕获的TypeError：e.slice不是函数

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

        statemenetInquiryParameter.isPrintZero = true;
        statemenetInquiryParameter.isPrintPayments = true;

        statemenetInquiryParameter.cst_stmt_to = new Date("April 12, 2016");
        statemenetInquiryParameter.customerCode = 007;

        $.ajax({

Answer 1

此错误是由ToDataSourceResult()引起的。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);
}

Hıpe这有助于......

从视觉检查提供的代码我怀疑我们在这里有两件事。

首先：

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

如果您要定义“远程”数据源，那么您需要为命令提供读取操作或将其绑定到集合（基于我的经验），这可能正在爆炸你遇到的错误。

除此之外，您似乎正在制作网格声明可以为您做的代码。

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};
}

然后应该像原来那样传递对象。

希望这能为您提供可行的解决方案。
