MVC - 将json结果发布到控制器，然后从控制器重定向

Question

作为MVC和淘汰赛的新手，我需要一些帮助。我试图获得一些JSON结果（作为字符串）发布到我的控制器，然后让控制器RedirectToAction到一个新的视图和操作。

问题：即使命中RedirectToAction，控制器也总是返回相同的视图。

（它通过重定向代码，然后在最后直接回到发布视图。）我不得不放置一个“下一步”的行动，这是有点尴尬。

ALSO：隐藏字段是存储/传递ID时的最佳方式吗？

Answer 1

的问题是，您所呼叫使用Ajax的添加方法，所以你需要使用window.location = url来更改为新视图。

你应该尝试是返回一个JsonResult用的GroupId它，在Ajax调用使用window.location的成功一部分，并改变看法。

模型

var newUrl="@Url.Action("Registration","Home")"; 

话外加上这个模型

self.save = function() { 
     self.lastSavedJson(JSON.stringify(ko.toJS(self.contacts), null, 2)); 
     var s = document.getElementById("GroupID").value 
     $.ajax({ 
      url: "/Home/Add/", 
      type: "POST", 
      data: { jsonString: JSON.stringify(ko.toJS(self.contacts)), groupID: s }, 
      success: function (result) { 
Code Change -----> window.location=newUrl+"/"+result; 
      }, 
      error: function (jqXHR, textStatus, errorThrown) { 
       var errorMessage = ''; 
       $('#message').html(jqXHR.responseText); 
      } 
     }); 

    }; 

我假设控制器只返回标识内。希望它有效。
