Ajax.BeginForm刷新整个页面中的MVC [英] Ajax.BeginForm refreshing the whole page in MVC

问题描述

我一直在尝试一些Ajax功能添加到我的MVC的网站，但是，我遇到一个问题关于页面清爽。我已经创建了我的主页侧边栏，它允许用户选择他们想要使用一个下拉列表来查看哪些RSS订阅的RSS视图。起初我用MVC中html.begin形式的选择，但是，我决定这将是一个很酷的功能有RSS馈线刷新，而不是整个页面刷新。我实现了ajax.begin形式，但整个页面仍然是令人耳目一新。

I've been trying to add some Ajax functionality to my mvc site, however, I run into a problem regarding page refreshing. I've created an rss view on my homepage sidebar, which allows the user to select which rss feed they want to view using a drop down list. Initially I was using the html.begin form option in mvc, however, I decided it would be a cool feature to have the rss feeder refresh, rather than having the whole page refresh. I implemented the ajax.begin form, but the whole page is still refreshing.

下面是我的看法里面的code：

Here is the code inside my view:

<div class="rss_feed">
    <h3>RSS Feed</h3>

    @using (Ajax.BeginForm("Index", "Home",
        new AjaxOptions
        {
            HttpMethod = "post",
            UpdateTargetId = "feedList"
        }))
    {
        @Html.DropDownListFor(x => x.SelectedFeedOption, Model.FeedOptions)
        <input type="submit" value="Submit" /> 
    }

    <div id="feedList">
        @foreach (var feed in Model.Articles)
        {
            <div class="feed">
                <h3><a href="@feed.Url">@feed.Title</a></h3>
                <p>@feed.Body</p>
                <p><i>Posted @DateTime.Now.Subtract(@feed.PublishDate).Hours hour ago</i></p>
            </div>   
        }
    </div>
</div>

当用户从下拉菜单中选择一个饲料类型，并点击提交按钮，饲料应更新到所选择的选项。

When the user selects a feed type from the drop down menu, and clicks the submit button, the feed should update to the selected option.

在_layout查看下面的包被装入：

In the _Layout view the following bundle is loaded:

@Scripts.Render("~/bundles/jquery")

任何帮助将是巨大的。

Any help would be great.

推荐答案

我使用jQuery的这个Ajax调用

I use an ajax call in jquery for this

$('#SelectedFeedOption').change(function() {
    $.ajax({
        url: "@(Url.Action("Action", "Controller"))",
        type: "POST",
        cache: false,
        async: true,
        data: { data: $('#SelectedFeedOption').val() },
        success: function (result) {
            $(".feedList").html(result);
        }
   });
});

然后把你的feedList div的内容在一个局部视图和控制器上

Then put the contents of your feedList div in a partial view and on your controller

public PartialViewResult FeedList(string data){
    Model model = (get search result);
    return PartialView("_feedList", model);
}

希望这有助于。
