我的JQuery AJax調用不會序列化表單數據並加載局部視圖

Question

我正在使用ASPNET MVC視圖提交一些搜索條件並使用結果加載部分視圖。 我正在對我的控制器/ Action進行ajax調用並加載局部視圖。 當我序列化表單時，序列化對象應該發送到我的操作方法，但這不起作用。 我也返回局部視圖，但它不渲染局部視圖的html。

請參閱下面的代碼，並在此處提出任何不正確或缺失的內容。

這是腳本：

$('#btnsearch').click(function () {
        var formData = new FormData();
        var form = $('form').serialize();
        alert(form);
        formData.append('Panel', form);
        $.ajax({
            url: "Email/GetEmails",
            type:'POST',
            dataType: 'html',
            data: formData,
            processData: false,
            contentType: false,
            success: function (result) {
                alert(result);
                $("._EmailPartial").html(result);
            },
            error: function () {
                alert('Failed to retrieve the Emails.');
            }
        });
    });

以下是主要和部分視圖：

@using AllturnaCRMOperations.Models
@model AllturnaCRMOperations.Models.EmailSearchPanel

@{
    ViewBag.Title = "Enter the filters to see emails";
}

<h3 class="text-center"><span>@ViewBag.Title</span> </h3>

                        @Html.ValidationMessageFor(model => model.CustomToDate, "", new { @class = "text-danger" })

 </div>

<p class="text-right" style=" margin-top:20px">

 <section class="row" id="emailPartial">
     <div class="SearchPanel">

             @*@Html.Partial("_EmailPartial", new List<Email>())*@
         </div>
     </div>
 </section>

局部視圖：

@model IEnumerable<AllturnaCRMOperations.Models.Email>

@{
    ViewBag.Title = "View";
}

<table class="table table-hover table-responsive scrollable table-striped">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Description)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.CreateDate)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CreateDate)
        </td>
        <td>
            @Html.ActionLink("Details", "Details", new { /* id=item.Name */ }) |
        </td>
    </tr>
}

</table>

和控制器：

public ActionResult GetEmails(EmailSearchPanel Panel)
        {
            List<Email> lstEmails = new EmailViewModel().BuildModel();
            return PartialView("_EmailPartial",lstEmails);
        }

這是我使用alert（表單）序列化后看到的圖片。

請幫我解決這個問題。 提前致謝。

1. 你的第一個問題是在你的AJAX調用中使用'form'而不是'formData'。 然后你的控制器應該得到你傳遞的表格值。

    $('#btnsearch').click(function () { var formData = new FormData(); var form = $('form').serialize(); alert(form); formData.append('Panel', form); $.ajax({ url: "Email/GetEmails", type: 'POST', dataType: 'html', data: form, processData: false, contentType: false, success: function (result) { alert(result); $("._EmailPartial").html(result); }, error: function () { alert('Failed to retrieve the Emails.'); } }); }); 

2. 你使用局部視圖的方式有點不正統，我建議你做更多的研究。 參考：

Answer 2

這解決了。 我的部分視圖正在呈現，然后頁面自動刷新。 我是因為我使用了button type = submit，它對服務器進行了完整的回發，所以它刷新了頁面並覆蓋了ajax結果。 我用type =按鈕更改了按鈕，結果按照我的預期呈現。
