仅发布 ASP.NET MVC - 编程之家

如何解决仅发布 ASP.NET MVC

我只喜欢在用户点击 Button type="submit" id="PostButton" 后更新 @Html.Partial("_CommentSection")。

目前我重新加载整个页面以查看新评论。但我认为拥有它并不好。

有没有办法做到这一点，你可以帮助我更多地实现我的目标。也许用jquery - 但我之前没有用过这个，不知道怎么做

我在 asp.net 项目中有此代码的部分视图：

@model MyProject.Models.Home

@foreach (var comment in MyProject.Controllers.HomeController.GetAllComments(Model.Id))
{
    <br />
    <div>
        <div>
            <a>
                @MyProject.Controllers.HomeController.GetUserName(comment.UserId)
            </a>
            added a comment -
            <span>
                <time>@comment.CommentCreated.ToString()</time>
            </span>
            <span id="edit-delete-comment">
                @using (Html.BeginForm("DeleteComment","Home"))
                {
                    @Html.AntiForgeryToken()

                    if (MyProject.Controllers.HomeController.CheckIfUserIsCreator(User.Identity.Name,comment.CommentId))
                    {
                        if (!MyProject.Controllers.HomeController.CheckDateOfComment(comment.CommentId))
                        {
                            <div class="form-actions no-color">
                                @Html.Hidden("returnUrl",this.Request.RawUrl)
                                @Html.Hidden("CommentId",comment.CommentId)
                                <input type="submit" value="Delete" class="t" />
                            </div>
                        }
                    }

                }
            </span>

        </div>
        <br />
        <div>
            <p>
                @comment.CommentText
            </p>
        </div>
    </div>
    <hr />
}

@using (Html.BeginForm("CreateComment","Home",FormMethod.Post,null))
{
    @Html.AntiForgeryToken()

    <div class="mt-5 d-flex flex-row">
        @Html.Hidden("returnUrl",this.Request.RawUrl)
        @Html.Hidden("HomeId",Model.Id)
        <textarea class="form-control" name="CommentText"></textarea>

        <button class="btn btn-secondary btn-block mt-2 post-btn" type="submit" id="PostButton">Post</button>

    </div>


}

我的观点：

<div id="partial-update">
    @Html.Partial("_CommentSection")
</div>

我的控制器（帖子被注释掉后更新页面）

[HttpPost]
[AllowOnlyOneRequest]
[ValidateAntiForgeryToken]
public void CreateComment([Bind(Include = "CommentId,CommentText,CommentCreated,UserId,HomeId")] Comment comment,string returnUrl,int HomeId)
{
    if (ModelState.IsValid)
    {
        comment.CommentCreated = DateTime.Now;
        comment.UserId = db.Users.FirstOrDefault(i => i.UserEmail == User.Identity.Name).UserId;
        comment.HomeId = HomeId;

        db.Comments.Add(comment);
        db.SaveChanges();
        //return Redirect(returnUrl);
    }

    //return Redirect(returnUrl);
}
