javascript - 如何将新创建的ID放入LocalStorage？

Question

我陷入了困境。我使用ajax将数据传递给 Controller ​​， Controller 有一个方法将数据传递给DAL，DAL返回一个int，即新创建的插入记录的ID。我的问题是如何获取返回的 ID 并将其放入 LocalStorage 中？

这是要提交的新 vendor

function NewVendorToSubmit() {
    var isItChecked;
    if ($("#sTaxEnabled").prop("checked")) {
        isItChecked = "1";
    }
    else isItChecked = "0";

    var Vendor = {
        VendorName: $("#txtVendorName").val(),
        Address1: $("#txtVendorAddress1").val(),
        Address2: $("#txtVendorAddress2").val(),
        City: $("#txtVendorCity").val(),
        State: $("#acVendorState").val(),
        Zip: $("#txtVendorZip").val(),
        VendorPhone: $("#txtVendorPhone").val(),
        VendorFax: $("#txtVendorFax").val(),
        Email: $("#txtEmail1").val(),
        Email2: $("#txtEmail2").val(),
        TaxEnabled: isItChecked
    };
    return Vendor;
}

这是我的 jquery 函数，它在按钮保存事件上被调用

function SubmitNewVendor() {
    var newVendor = NewVendorToSubmit();
    $.ajax({
        type: "POST",
        url: URLParam.AddNewVendor,
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify(newVendor),
        success: function (data, textStatus, jqXHR) { },
        complete: function (e) {
            ClearVendorFields();
            GetVendorGridData();
            //CloseTheWindow();
        }
    })
}

这是它正在调用的 Controller 方法

[HttpPost]
public int AddVendor(NewVendorToAdd nvta)
{
    DAL = new UsherDAL();
    int addedVendorID = DAL.AddNewVendor(nvta);
    return addedVendorID;
}

这是从 DAL 调用的方法

public int AddNewVendor(NewVendorToAdd nvta)
{
    Vendor vendor = new Vendor();
    Address address = new Address();
    VendorAddressXREF vendoraddressxref = new VendorAddressXREF();

    vendor.VendorName = nvta.VendorName;            
    int newVendorID = InsertVendor(vendor);

    address.Line1 = nvta.Address1;
    address.Line2 = nvta.Address2;
    address.City = nvta.City;
    address.ZipCode = nvta.Zip;
    address.StateID = nvta.State;
    int newAddressID = InsertAddress(address);

    vendoraddressxref.VendorID = newVendorID;
    vendoraddressxref.AddressID = newAddressID;

    int newVendorAddressXREFID = InsertVendorAddressXREF(vendoraddressxref);
    return newVendorID;
}

那么我该如何从 AddNewVendor 获取返回的 int 并将其放入 LocalStorage，而无需再次往返数据库？

似乎 vendor 的 ID 作为对 POST 请求的响应而返回，要将其存储在本地存储中，您可以执行以下操作:

 $.ajax({
    ...,
    success: function (data, textStatus, jqXHR) { 
         if(window.localStorage){
             localStorage.vendorID = data;
         }
    },
    ...
})
