我正在尝试在 MVC4 中使用 Jquery 模型对话框，使用 Razor 对话框显示正常，但 AjaxOptions.OnSuccess javascript 函数在我单击更新按钮后未调用，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

CarController.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);
        }
    }

索引.cshtml

@model IEnumerable<AjaxSamples.Models.CarModel>

@{
ViewBag.Title = "Index";
}
<div id="commonMessage"></div>
<p>
@Html.ActionLink("Create New", "Create")

@foreach (var item in Model) {

    $(".editLink").click(function () {
        //change the title of the dialog
        linkObj = $(this);
        var dialogDiv = $('#updateDialog');
        var viewUrl = linkObj.attr('href');
        $.get(viewUrl, function (data) {

            dialogDiv.html(data);
            //validation
            var $form = $("#updateCarForm");

最佳答案

需要以下 Jquery 文件

jquery.unobtrusive-ajax.js

关于javascript - ASP.NET MVC4 AJAX.BeginForm AjaxOptions OnSuccess 未调用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19265605/
