在ajax调用中加载局部视图

Question

我是MVC的新手。 我开始创建一个项目，但遇到了一个大问题。 请帮助我。 说明：我具有一个动作链接的视图并加载一个局部视图

@model List<MuthuTag.Models.LoadPostModel>
@{
    ViewBag.Title = "LoadPost";
}

@Html.ActionLink("Add New Post","Post","Home")

<h2>LoadPost</h2>
<div>
    <table>
       @foreach (var Item in Model)
       {
        <tr>
            <td>
               @Item.TagId
            </td>
            <td>
                @Item.TagTitle
            </td>
            <td>@Item.TagContent</td>
        </tr>
       }
    </table>
</div>

在这种情况下，您可以单击“添加新的后期操作”链接，以免加载另一个视图控制器代码

  public ActionResult Post()
        {
            return View();
        }

加载视图

@model MuthuTag.Models.LoadPostModel
@{
    ViewBag.Title = "Add New Post";
}
<script src="~/Content/jquery-1.8.3-min.js"></script>
<h2>Post</h2>
<link href="~/Content/magicsuggest-1.3.1.css" rel="stylesheet" />
<script src="~/Content/magicsuggest-1.3.1.js"></script>
<div id="Post">
    <table>
    <tr>
        <td>
              @Html.LabelFor(m => m.TagId)


        </td>
        <td>
                 @Html.TextBoxFor(m => m.TagId)
        </td>
        </tr>
          <tr>
        <td>
              @Html.LabelFor(m => m.TagTitle)


        </td>
        <td>
                    @Html.TextAreaFor(m => m.TagTitle)
        </td>
    </tr>
          <tr>
        <td>
              @Html.LabelFor(m => m.TagContent)


        </td>
        <td>
                  @Html.TextAreaFor(m => m.TagContent)
        </td>
    </tr>

       </table>
                <div id="ms-tpl"></div>

                    sortOrder: 'name',
                    maxResults: false
                });
                $('#Register').click(function () {
                    debugger;
                    var dataplus = ms1.getValue();
                    var tagid = document.getElementById('TagId').value;
                    var tagtitle = document.getElementById('TagTitle').value;
                    var tagcontent = document.getElementById('TagContent').value;

                        type: 'POST',
                        cache: false,
                        success: function (data) {

                        }

                    });
                });

                $('#click').click(function () {
                    debugger;
                    alert(ms1.getValue());

                });

        </script>    

        [HttpPost]
        public ActionResult GetPost(Profile model)
        {
            SqlConnection con = new SqlConnection(conn);
            con.Open();
            string tagid = Request.Params["tagid"];
            string tagtitle = Request.Params["tagtitle"];
            string tagcontent = Request.Params["tagcontent"];
            SqlCommand cmd = new SqlCommand("CreatePostDetail", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@TagId", tagid);
            cmd.Parameters.AddWithValue("@TagContent", tagcontent);
            cmd.Parameters.AddWithValue("@TagTitle", tagtitle);
            //string name = Session["UserName"].ToString();
            string name = "123";
            cmd.Parameters.AddWithValue("@UserName", name);
            cmd.ExecuteNonQuery();
            con.Close();
            return View("Index");
        }

因此，如果用户单击“保存”按钮，它将转到控制器

[HttpPost]
        public ActionResult GetPost(Profile model)
        {
            SqlConnection con = new SqlConnection(conn);
            con.Open();
            string tagid = Request.Params["tagid"];
            string tagtitle = Request.Params["tagtitle"];
            string tagcontent = Request.Params["tagcontent"];
            SqlCommand cmd = new SqlCommand("CreatePostDetail", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@TagId", tagid);
            cmd.Parameters.AddWithValue("@TagContent", tagcontent);
            cmd.Parameters.AddWithValue("@TagTitle", tagtitle);
            //string name = Session["UserName"].ToString();
            string name = "123";
            cmd.Parameters.AddWithValue("@UserName", name);
            cmd.ExecuteNonQuery();
            con.Close();
            return View("Index");
        }

我返回索引，以使添加的内容显示在主页上，但仅保留在帖子视图中，但数据保存在数据库中。 （从actionlink（post）的简单方法->从再次加载主页的新视图中加载新视图，但仍保留在post视图中）。

Answer 1

在主视图中创建一个容器div：

@model List<MuthuTag.Models.LoadPostModel>
@{
    ViewBag.Title = "LoadPost";
}

@Html.ActionLink("Add New Post","Post","Home")

<h2>LoadPost</h2>
<div>
    <table>
       @foreach (var Item in Model)
       {
        <tr>
            <td>
               @Item.TagId
            </td>
            <td>
                @Item.TagTitle
            </td>
            <td>@Item.TagContent</td>
        </tr>
       }
    </table>
</div>
<div id="container">
</div>

并在您的ajax调用成功函数中执行以下操作：

$.ajax({
         url: '@Url.Action("GetPost")' + '?tagid=' + tagid + '&tagtitle=' + tagtitle + '&tagcontent=' + tagcontent + '&dataplus=' + dataplus,
         type: 'POST',
         cache: false,
         success: function (data) {

         $('#container').html(data);

          }

       });

按照此堆栈溢出答案https://stackoverflow.com/a/12006362/3541042中的指定，您可以将重定向URL发送回ajax回调并导航至该URL。

如果url是静态的，则可以直接从Java脚本本身进行操作，如下所示。

$('#Register').click(function () {
    debugger;
    var dataplus = ms1.getValue();
    var tagid = document.getElementById('TagId').value;
    var tagtitle = document.getElementById('TagTitle').value;
    var tagcontent = document.getElementById('TagContent').value;
    $.ajax({
        url: '@Url.Action("GetPost")' + '?tagid=' + tagid + '&tagtitle=' + tagtitle + '&tagcontent=' + tagcontent + '&dataplus=' + dataplus,
        type: 'POST',
        cache: false,
        success: function (data) {
           window.location.href = '@Url.Action("Index", "<controller name>")';
        }
    });
});
