Ungayibuyisa kanjani impendulo efanele ngephutha ku-ASP.NET MVC 3.0 nge-JSON?

Nginenkinga yokuxazulula le nkinga. umshini wasendaweni (Win7 / VS2010 / IIS 7.5) nomunye umshini ofanayo wonjiniyela, ikhodi elandelayo ibuyisa ikhodi yesimo esingu-500, futhi umbhalo ophendulayo uthi "Ayikwazanga ukuthola umsebenzisi ngekheli le-imeyili elicacisiwe".

Lapho ngisebenzisa isiza iseva yami yokuhlola (Win2008 R2 / IIS7.5) ibuyisa ikhodi yesimo elungile, kepha uhlobo lokuqukethwe lusethelwe ku- "text / html" futhi impenduloText ayiqukethe umyalezo.

Ngizamile ukucisha inkambiso amaphutha kuseva, angenzanga mehluko. Ngabe ukhona umuntu ongabona ukuthi inkinga ingaba yini?

Nginefomu elilungiselelwe kusetshenziswa indlela ye-AjaxHelper.BeginForm:

@using (Ajax.BeginForm("FindUser", new AjaxOptions {OnSuccess="findComplete", OnFailure="findFailed"}) 
{
    <fieldset>
        @Html.EditorFor(m => m.UserEmail)
        <div class="form-item button search">
            <input type="submit" value="Find"/>
        </div>
        <div id="find-err" class="message error hidden">
            <div class="contents"></div>
        </div>
    </fieldset>
}

Enephutha ekuphatheni umsebenzi we-JavaScript:

function findFailed(result) {
    var error = result.responseText;
    if (error) {
        $('#find-err .contents').text(error).slideDown();
    }
}

I isenzo sesilawuli sibamba noma yimaphi amaphutha bese sibuyisa umlayezo:

[HttpPost]
public ActionResult FindUser(FindUserModel model) 
{
    try
    {
        // code to find user

        if (user == null) 
        {
            throw new Exception("Could not locate user with specified email address.");
        }

        if (Request.IsAjaxRequest())
        {
            return Json(new { id = user.Id, name = user.Name }, JsonRequestBehavior.AllowGet);
        }

        model.FoundUser = user;
        return View("Details", model);
    }
    catch (Exception ex)
    {
        if (Request.IsAjaxRequest())
        {
            Response.StatusCode = 500;
            return Json(ex.Message, JsonRequestBehavior.AllowGet);
        }

        ModelState.AddModelError("UserEmail", ex.Message);
        return View(model);
    }
}

Noma yiluphi usizo luzothokozelwa kakhulu:)
