当我从其他Action或视图中调用它时，Json会出错，但是直接运行时它会成功吗？

I have an action method that in the view part I Use Json to get data from other action in my controller , it go to success method when i call it directly , (put routConfig action eqaul to this Action )

我有一个动作方法,在视图部分我使用Json从我的控制器中的其他动作获取数据,当我直接调用它时,它转到成功方法,(将routConfig动作eqaul放到此Action)

but when i call the action from links it goes to error , I dont know why ?!

但是当我从链接调用动作时它会出错,我不知道为什么?!

Controller:

[HttpGet]
    public ActionResult PieRenderer()
    {
        return View();
    }

    [HttpPost]
    public JsonResult GetPieRenderer()
    {
        var DbResult = from d in db.Rep_TaskTypeQueuChart(0, 1)
                       select new
                       {
                           d.TaskTypeName,
                           d.WorkCount
                       };
        //return Json(DbResult, JsonRequestBehavior.AllowGet);
        return Json(DbResult);
    }

                alert(response.toString());
            }


        });

    </script>
</div>

If I change RoutConfig action="PieRenderer" it shows the result. but if i run the main dashboard view , and there i had a actinlink or a href to PieRenderer method , it goes to error method ()...

如果我更改RoutConfig action =“PieRenderer”,它会显示结果。但是,如果我运行主仪表板视图,并且我有一个actinlink或一个href到PieRenderer方法,它会转到错误方法()...

I Find the answer , the problem because of this part : url: "Cartable/GetPieRenderer"

我找到答案,问题因为这部分:url:“Cartable / GetPieRenderer”

it should be change like this : url: "/Cartable/GetPieRenderer",

它应该像这样改变:url:“/ Cartable / GetPieRenderer”,
