使用 RedirectToAction 方法时视图内容不刷新

Question

我创建了一个简单的 asp.net 核心 mvc 项目。

HomeController.cs 如下所示：

public class HomeController : Controller
{
    public HomeController()
    {
    }

    public IActionResult Index(string name, string desc)
    {
        Random random = new Random();
        TestViewModel viewModel = new TestViewModel();
        viewModel.Id = random.Next(0,7).ToString();
        viewModel.Name = name;
        viewModel.desc = desc;
        return View(viewModel);
    }

    public IActionResult Update()
    {
        //return View("Index", new TestViewModel() { Name="Steven", desc="Hello" });
        return RedirectToAction("Index", new { name = "Steven", desc="Hello" });
    }
}

ViewModel class:

public class TestViewModel
{
    public string Name { get; set; }
    public string Id { get; set; }
    public string desc { get; set; }
}

Razor 页面：

<!--
@{
    ViewData["Title"] = "Home Page";
}
@model WebApplication6.Controllers.TestViewModel

<div class="main">
    <form method="get">
        <label name="id" asp-for="Id">@Model.Id</label>
        <label asp-for="Name">@Model.Name</label>
        <input name="desc" type="text" value="@Model.desc" />
        <input name="t1" type="button" onclick="executeInsert()"/>
    </form>
</div>

<script type="text/javascript">
    function executeInsert() {
        $.get('/Home/Update');
    }
</script> -->

当我点击按钮时，我实际上已经发送了获取请求并且它已经重定向到索引操作，但是浏览器没有刷新视图内容。

这个函数不能这样调用$.get('/Home/Update'); 您可以通过这种方式更优雅地完成您想要实现的目标，您可以试试这个示例：

控制器加载视图：

 public IActionResult Index(string name, string desc)
        {
            Random random = new Random();
            TestViewModel viewModel = new TestViewModel();
            viewModel.Id = random.Next(0, 7).ToString();
            viewModel.Name = name;
            viewModel.desc = desc;
            return View(viewModel);
        }

控制器提交新值：

        [HttpPost]
        public IActionResult Update(TestViewModel model)
        {
          return RedirectToAction("Index", new { name = model.Name, desc = model.desc });
        }

查看：

@model MVCApps.Models.TestViewModel

@{
    ViewData["Title"] = "ViewContentTestIndex";
}

<h3>View Content Test Index</h3>
<hr />

@using (Html.BeginForm("Update", "UserLog"))
{

    <div>
        Id: <label name="id" asp-for="Id">@Model.Id</label>
        Name:<label asp-for="Name">@Model.Name</label>
        Desc:<label asp-for="desc">@Model.desc</label>
    </div>

    <hr />
    <div>

        <label asp-for="Name">Name</label>
        <input name="Name" type="text" value="@Model.Name" />
        <label asp-for="Name">Desc</label>
        <input name="desc" type="text" value="@Model.desc" />
        <input id="Button" type="submit" value="Save" class="btn btn-primary" />
    </div>

   
}
