javascript - ASP.NET MVC4 AJAX.BeginForm AjaxOptions OnSuccess 未调用

Question

我正在尝试在 MVC4 中使用 Jquery Model Dialog 使用 Razor 对话框显示正常，但是在我单击更新按钮后 AjaxOptions.OnSuccess javascript 函数没有调用，但它被重定向到 http://<>:3738/Cars/Edit/1 ?Length=4 我不知道为什么会这样。

这是我的代码

汽车控制器.cs

public class CarsController : Controller
{
    private ExpDb db = new ExpDb();

    //
    // GET: /Cars/

    public ActionResult Index()
    {
        return View(db.Cars.ToList());
    }



    //
    // GET: /Cars/Edit/5

    public ActionResult Edit(int id = 0)
    {
        CarModel carmodel = db.Cars.Find(id);
        if (carmodel == null)
        {
            return HttpNotFound();
        }
        return PartialView(carmodel);
    }

    //
    // POST: /Cars/Edit/5

    [HttpPost]
    public JsonResult  Edit(CarModel carmodel)
    {
        if (ModelState.IsValid)
        {

            db.Entry(carmodel).State = EntityState.Modified;
            db.SaveChanges();
            //return RedirectToAction("Index");
             return Json(JsonResponseFactory.SuccessResponse(carmodel),JsonRequestBehavior.DenyGet);
        }
      else {
            return Json(JsonResponseFactory.ErrorResponse("Please review your form"), JsonRequestBehavior.DenyGet);
        }
    }

Answer 1

需要以下 Jquery 文件

jquery.unobtrusive-ajax.js

Answer 2

我遇到的问题是我在 $(document).ready() 中声明了成功函数。我把它移到外面，它起作用了。

IE：

@using (Ajax.BeginForm("DialogTest", "Main", new AjaxOptions { HttpMethod = "Post", OnSuccess = "ajaxSuccess" }))
{
    <input type="button" id="info" value="Info" />
    <input type="button" id="confirm" value="Confirm" />
    <input type="button" id="wait" value="Wait" />
    <input type="button" id="ask" value="Ask" />
    <br /><br />
    <input type="submit" value="Submit" />
}



@section Scripts
{
    <script type="text/javascript">

        var ajaxSuccess = function () {
            alert('this is ajaxSuccess');
        }


        $(document).ready(function () {
            // do not declare ajaxSuccess here

            $('#mainForm').submit(function () {
                radarApp.InfoDialog("form submitted.");
                return false;
            });

// snip

我遇到过同样的问题。最初，我的脚本位于部分视图的头部......这导致了我的问题。

我将它移到了托管我的部分视图的视图的标题中，并且一切正常。我的视图是托管在 mvc 应用程序中的引导页面，其布局设置为：“Layout = Nothing”。如果您的控制器操作正在加载视图，则 jquery.unobtrusive-ajax.js 位置肯定存在问题...

尝试：

@using (Ajax.BeginForm("Edit", new {controller = "Cars"} , new AjaxOptions

Answer 5

您需要在 BeginForm 调用中再添加一个参数：

Ajax.BeginForm("Edit","Cars", null, new AjaxOptions
               {
                   InsertionMode = InsertionMode.Replace,
                   HttpMethod = "POST",
                   OnSuccess = "updateSuccess"
               }, new { @id = ""updateCarForm })

null用于 RouteValueDictionary。以下是 Ajax.BeginForm 方法的所有重载。

Answer 6

You can use Post method directly inside the Script tag for call the controller method like :

@using (Html.BeginForm("Edit", "Cars", FormMethod.Post, new { id = "updateCarForm" }))
{
  .......Yourdata......
}

and then in the Jquery

function PostForm(url) {
    $("#updateCarForm").valid();
    if ($("#updateCarForm").valid()) {
    $.post(url, $("#updateCarForm").serialize(), function (data) { updateSuccess(data); });
    }
}

Answer 7

@Alex 的代码中存在语法错误，这应该可以工作：

Ajax.BeginForm("Edit","Cars", null, new AjaxOptions
           {
               InsertionMode = InsertionMode.Replace,
               HttpMethod = "Post",
               OnSuccess = "updateSuccess"
           }, new { id = "updateCarForm" })
{ /* Razor code */ }

具体来说，您应该查看Ajax.BeginForm().
