MVC Ajax更新局部视图

Question

我想在每次单击ActionLink时更新局部视图.我将相同的模型作为主视图传递给局部视图.问题是部分视图没有得到更新.不确定我是否在正确的轨道上.

查看:

@model MyPoll.Models.Poll

@Ajax.ActionLink("For", "AddPositive", new RouteValueDictionary { {"id", Model.Id }},new AjaxOptions() { UpdateTargetId = "countsDiv" })

<div id="countsDiv">
    @Html.Partial("Counts", Model)
</div>

部分:

@model MyPoll.Models.Poll

Positive count : @Model.PositiveCount
Negative count : @Model.NegativeCount

控制器动作:

public ActionResult AddPositive(int id)
{
    Poll poll = db.Polls.Find(id);
    poll.PositiveCount++;
    db.SaveChanges();

    return View(poll);
}

脚本也被引用:

 <script src="/Scripts/jquery.unobtrusive-ajax.min.js" type="text/javascript"></script>
 <script src="/Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>
 <script src="/Scripts/MicrosoftAjax.js" type="text/javascript"></script>
 <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>

Answer 1

固定:

在行动:

public **PartialViewResult** AddPositive(int id)
    {
        Poll poll = db.Polls.Find(id);
        poll.PositiveCount++;
        db.SaveChanges();

        return **PartialView**("Counts", poll);
    }
