在asp.net mvc 3项目中渲染局部视图onclick

Question

在我的mvc项目中,我有一个简单的项目列表,其中包含如下所示的crud操作:

<tbody>
 @{
    foreach (var item in Model)
    {            
         <tr>

            <td>@item.Title</td>
            <td>@item.Body</td>
            <td>@item.Price</td>
            <td><span class="EditLink ButtonLink" noteid="@item.Id">Edit</span>&nbsp;|&nbsp;<span>@Html.ActionLink("Delete", "Delete", new { id = @item.Id})</span>
                            &nbsp;|&nbsp; @Html.ActionLink("Detalji", "Details", new { id = @item.Id})
             </td>
        </tr>
     }
  }

</tbody>

我想知道当我点击详细信息时,可以将详细信息视图呈现为表格下的部分视图.我的意思是当我clik细节向我展示细节视图时,我希望它在我的桌子下面的某个div或段落中.

请帮忙.

你可以使用AJAX.但首先让我们通过摆脱这些循环并用显示模板替换它们来改进代码:

@model IEnumerable<SomeViewModel>
<table>
    <thead>
        <tr>
            <th>Title</th>
            <th>Body</th>
            <th>Price</th>
            <th>actions ...</th>
        </tr>
    </thead>
    <tbody>
        @Html.DisplayForModel()
    </tbody>
</table>

<div id="details"></div>

然后定义一个显示模板(~/Views/Shared/DisplayTemplates/SomeViewModel.cshtml):

@model SomeViewModel
<tr>
    <td>@Html.DisplayFor(x => x.Title)</td>
    <td>@Html.DisplayFor(x => x.Body)</td>
    <td>@Html.DisplayFor(x => x.Price)</td>
    <td>
        <!-- no idea what the purpose of this *noteid* attribute on the span is
             but this is invalid HTML. I would recommend you using the
             HTML5 data-* attributes if you wanted to associate some
             metadata with your DOM elements
        -->
        <span class="EditLink ButtonLink" noteid="@Model.Id">
            Edit
        </span>
        &nbsp;|&nbsp;
        <span>
            @Html.ActionLink("Delete", "Delete", new { id = Model.Id })
        </span>
        &nbsp;|&nbsp; 
        @Html.ActionLink(
            "Detalji",                      // linkText
            "Details",                      // actionName
            null,                           // controllerName
            new { id = Model.Id },          // routeValues
            new { @class = "detailsLink" }  // htmlAttributes
        )
    </td>
</tr>

现在剩下的就是在单独的javascript文件中AJAXify这个详细信息链接:

$(function() {
    $('.detailsLink').click(function() {
        $('#details').load(this.href);
        return false;
    });
});

当然,您假设您有以下行动:

public ActionResult Details(int id)
{
    SomeDetailViewModel model = ... fetch the details using the id
    return PartialView(model);
}
