Question

我正在尝试更新部分视图但无法更新。我正在分享我到目前为止所做的代码。

动作：

public ActionResult AddReview([Bind(Include = "ReviewId,ProductId,ReviewerName,ReviewText,Rating,Time,Summary")]
            Review review, int? id)
        {



            var reviewsList = new List<Review>();
            reviewsList.Add(review);

            if (ModelState.IsValid)
            {
                review.Time = DateTime.Now;
                review.ProductId = id.Value;
                db.Reviews.Add(review);
                db.SaveChanges();
                if (Request.IsAjaxRequest())
                {
                    // return HttpNotFound();

                    return PartialView("_Reviews", reviewsList);
                }
            }



            return HttpNotFound();
        }

这个JQuery代码：

   $(function () {
    var ajaxFormSubmit = function () {
        var $form = $(this);
        var options = {
            url: $form.attr("action"),
            type: $form.attr("method"),
            data: $form.serialize()
        };

        $.ajax(options).done(function (data) {
            var $target = $($form.attr("data-consumer-target"));
            var $newHtml = $(data);
         //   $target.replaceWith($newHtml);
            $target.append($newHtml);
            $newHtml.effect("highlight");
            success: alert('Thanks for your review');
            $("#ajax-contact-form").find('input, textarea').val("");


        });

        return false;
    };

    $("form[data-consumer-ajax='true'").submit(ajaxFormSubmit);
});

这是部分视图_评论：

@model IEnumerable<ConsumerSimpleNew.Models.Entities.Review>

<div id="reviews">
    @foreach (var item in Model)
    {
        <h5>
            <span class="color"> @Html.DisplayFor(modelitem => item.ReviewerName)</span> - @item.Time.ToString("MMM dd-yyyy")
        </h5>

        <h6>Summary - @Html.DisplayFor(modelitem => item.Summary)</h6>
        <h6>Rating: @Html.DisplayFor(modelitem => item.Rating)</h6>
        <div class="std">@Html.DisplayFor(modelitem => item.ReviewText)</div>
        <hr />
    }
</div>

这是详细信息视图：

 @Html.Partial("_Reviews", Model.Reviews)


                            <div class="form-add">
                                <h2>Write Your Own Review</h2>

                                <form method="post" action="@Url.Action("Details")"
                                      data-consumer-ajax="true" data-consumer-target="#reviews">


                                    @Html.AntiForgeryToken()

我已经使用并搜索了很多可能的解决方案，但我无法获得最好的解决方案。请帮助我，我正在犯错误。

Answer 1

我以前从未见过这样的ajax。尝试将您的ajax调用更改为此

$('.btnSubmit').on('click', function(){
    $.ajax({
        url: '@Url.Action("Action", "Controller")',
        type: 'post',
        cache: false,
        async: true,
        data: { id: "frmUser" },
        success: function(result){
            $('.divPartial').html(result);
        } 
    });
});

这会将返回的部分视图放入div divPartial

的div中

Answer 2

看起来你正在传递＆＃34;评论＆＃34;您的部分视图，但您的部分视图正在等待

IEnumerable<ConsumerSimpleNew.Models.Entities.Review>

在你的jquery调用中添加一个错误：section并查看它是否被命中？

if (ModelState.IsValid)
        {
            review.Time = DateTime.Now;
            review.ProductId = id.Value;
            db.Reviews.Add(review);
            db.SaveChanges();
        }
        if (Request.IsAjaxRequest())
        {
           // return HttpNotFound();
        var reviewsList = new List<Review>();
        reviewsList.Add(review);

            return PartialView("_Reviews", reviewsList);
        }

无法使用mvc 4中的jquery ajax更新部分视图
