Question

这是ASP.NET mvc项目。我试图用ajax获取4个表数据。首先，我创建新类然后使用jsonresult，然后在视图中我使用了ajax。

[HttpPost]
    public JsonResult GetallData(int id)
    {
        MultipleViewModel model = new MultipleViewModel();
        List<InformationSecurityData> iso = db.InformationSecurityDatas.Where(x => x.Supplier_ID == id).ToList();
        List<SurveyForm> tender = db.SurveyForms.Where(x => x.Supplier_ID == id ).ToList();
        List<ProcurementData> procurement = db.ProcurementDatas.Where(x => x.Supplier_ID == id ).ToList();
        List<Supplier> supp = db.Suppliers.Where(x => x.Supplier_ID == id ).ToList();

        model.Inf_Sec_Dat = iso;
        model.Proc_Dat = procurement;
        model.Tender_Dat = tender;
        model.Supp_dat = supp;
        string json = JsonConvert.SerializeObject(model, 
        Formatting.Indented,
        new JsonSerializerSettings
        {
            ReferenceLoopHandling = ReferenceLoopHandling.Serialize
        });

        return Json(model, JsonRequestBehavior.AllowGet);
    }

控制器中的功能

      <script type="text/javascript">
        iso_data = [];
        tender_data = [];


        $(document).ready(function () {
            $("#GetallData").click(function () {
                var id = $("#id").val();
                $.ajax({
                    url: '/Dashboard/GetallData/' + id,
                    type: 'POST',
                    dataType: 'json',
                    success: function (data) {
                        alert("success ");

视野中的ajax

public class MultipleViewModel
{
    public List<InformationSecurityData> Inf_Sec_Dat { get; set; }
    public List<ProcurementData> Proc_Dat { get; set; }
    public List<SurveyForm> Tender_Dat { get; set; }
    public List<Supplier> Supp_dat { get; set; }

}

viewmodel class

我无法获取数据？我尝试了一些解决方案，但问题没有解决。究竟我需要纠正什么？你能告诉我到底我的错误是什么，还是与代码的这些部分有关？我得到了这个

 System.StackOverflowException
 HResult=0x800703E9
 Message=Exception of type 'System.StackOverflowException' was thrown.

Answer 1

在你的JSON函数上放一个断点，你得到id吗？我认为您的网址错误，应该是：

  URL: "/Dashboard/GetallData/",
  data: { id: id },
  cache: false,
  type: "POST",
  success: function (data) {
      alert("success ");
  },
  error: function (reponse) {
      alert("error : " + reponse);
  }
