【问题描述】:
我有两个部分视图“MyPopular”和“MyBlogs”。还有两个控制器——“ArticleController.cs”和“ThePopularController.cs”。这两个部分视图都包含按钮。
最初它在索引视图中呈现两个部分视图。
在博客点击的帖子操作处理程序中,它被要求重定向到“BlogHome”操作,它将返回一个简单的字符串“Blog Home”(而不是视图)。在流行点击的后操作处理程序上,它被要求重定向到“PopularHome”操作,它将返回一个简单的字符串“Popular Home”。但是目前,当我单击任何按钮时,它会呈现 localhost:1988/Article index;没有部分内容。
注意:即使我使用了 ContentResult 和 ActionResult,结果也是一样的。 注意:如果我通过错误的方式来完成如此简单的任务,请强调。
我们如何纠正它以进行正确的重定向?
//文章控制器

//Index returns no model
return View();

return "Blog Home";

[ChildActionOnly]
public ActionResult MyBlogs()
{
Thread.Sleep(500);
return PartialView(GetAllBlogEntries());

[HttpPost]
public void MyBlogs(string blogclick)
{
RedirectToAction("BlogHome");

【问题讨论】:
-
你有一些基本的误解。在您的 index.cshtml 中,您希望使用 ActionLink,而不是 Action。 Action 将尝试执行该操作,在这种情况下是不合适的 HTTP 重定向,而不是提供您可以单击的链接。我确定这是您想要的链接。鉴于不需要 ChildActionOnly - 它会阻止您想要的 - 或 POST 操作,因为它将是一个 GET 请求。我可能对你想要达到的目标有误,但我认为你让它变得比它需要的更复杂。
