Mvc Ajax JQuery Uncaught TypeError

我对Grid.MVC Ajax有问题。我找到了一个使用它的项目，我正在尝试使它适应我的项目。事实上，加载网格时会出现错误

Uncaught TypeError: Cannot read property 'length' of undefined
at HTMLDivElement.<anonymous> (<anonymous>:1:382)
at Function.each (jquery-3.3.1.js:354)
at jQuery.fn.init.each (jquery-3.3.1.js:189)

at done (jquery-3.3.1.js:9305)
at XMLHttpRequest.<anonymous> (jquery-3.3.1.js:9548)

似乎JQuery找到了网格。如果我在这一行之后尝试，什么都不会发生。因此，我认为数据问题一定是.gridmvc（）

Edit4

我解决了这个问题。在包含网格的父页面中，在网格本身之前有一个类为“grid mvc”的div。这就是为什么脚本不起作用

现在我必须修复另一个错误。找不到action GridPager，但我认为它会更容易解决。

从下面的div类中删除grid mvc

  <div class=" hidden-xs grid-mvc">
        @{
            HtmlGrid<OnlineWeb.Models.usp_Proc_Result> mvcGrid = null;
            GridMvc.Pagination.GridPager pager = new GridMvc.Pagination.GridPager();
        }

@{
HtmlGrid mvcGrid=null；
GridMvc.Pagination.GridPager pager=新建GridMvc.Pagination.GridPager（）；
}

我假设这些asp.net助手在前端呈现JavaScript。你能粘贴渲染的JavaScript吗？这听起来不像是一个订单问题，更像是一个缺少数据的问题，特别是一个结果（可能来自ajax调用），它应该是一个数组，但不是。@War10ck完成了。忽略class属性，因为我发现了一种显示带有asp.net帮助程序的glyphicon的好方法。此外，我真的不明白你在寻找什么，因为这些助手在网格中工作。也许ajax调用之间存在冲突？

public ActionResult GetGrid()
{
    var items = db.question.Where(x => x.statusquestion.IntituleStatusQuestion != "Supprimée").OrderByDescending(x => x.idQuestion);
    var grid = gridMvcHelper.GetAjaxGrid<question>((IOrderedQueryable<question>)items);

    return PartialView(GRID_QUESTION_PATH, grid);
}

[HttpGet]
public ActionResult GridPager(int? page)
{
    var items = db.question.Where(x => x.statusquestion.IntituleStatusQuestion != "Supprimée").OrderByDescending(x => x.idQuestion);
    var grid = gridMvcHelper.GetAjaxGrid<question>((IOrderedQueryable<question>)items, page);
    object jsonData = gridMvcHelper.GetGridJsonData(grid, GRID_QUESTION_PATH, this);

    return Json(jsonData, JsonRequestBehavior.AllowGet);
}
