使用ASP.Net MVC从JQuery发布中丢失上下文 [英] Losing context from JQuery post with ASP.Net MVC

问题描述

我在页面上有一个JQuery对话框，它调用如下内容:

I have a JQuery dialog box on a page that calls something like this:

$.post("/MyController/MyAction", { myKey: key} //...

成功到达这里:

[HttpPost]
public ActionResult MyAction(int myKey)
{
   //do some stuff
   return RedirectToAction("AnotherAction");       
}

问题在于RedirectToAction对Web浏览器没有影响.我猜这是因为JQuery帖子有点在不同的踩"位置，所以它不知道将响应发送到哪里?如何让浏览器加载新的响应?

The problem is that the RedirectToAction has no effect on the webbrowser. I am guessing this is because the JQuery post is kinda on a different 'tread' so it doesn't know where to send the response? How do I get the browser to load the new response?

推荐答案

是的，$.post正在执行ajax发布，并且该操作将不会重定向.

Yes, the $.post is doing an ajax post and the Action will not redirect.

无论如何，如果为什么要重新命名，为什么不提交表单，而无需ajax.

If you are reditecting anyway, why not just do a form submit, no need for ajax.

或者，您可以执行$.get并返回JsonResult来指示成功/失败，然后使用jQuery/javascipt进行重定向.

Alternatively you could do a $.get and return a JsonResult to indicate success/failure and redirect using jQuery/javascipt.

更新

类似这样的东西:

您可以在其中设置OK或ERR，并在其中添加任何对象作为项目"，这些对象可以在View上使用，也可以是错误消息，URL重定向到等

Where you can set OK or ERR as a result and add any object as the "item" which can be something to use on the View or an error message, url to redirect to etc

[HttpPost] 
public JsonResult MyAction(int myKey) 
{ 
   //do some stuff 
   return new JsonResult { Data = new { Item = item, Result = "OK/ERR" } };
}
