Question

我制作了一个简单的MVC程序。我创建了3个按钮来插入，更新或删除员工。但是当我点击按钮时，动作方法没有被执行＆amp;为什么相同的代码在我朋友的系统中起作用，但在我的系统中不起作用。我们都使用相同的MVC 4.这里的代码

控制器

public ActionResult Edit_Update_Delete_Insert_EMP()
    {

        EmployeeModel em = new EmployeeModel();
        ActionResult ar = View(em);
        return ar;
    }

    [HttpPost]
    public ActionResult Edit_Update_Delete_Insert_EMP(EmployeeModel em, string Employee)
    {
        if (Employee == "Insert")
        { 
        }
        if (Employee == "Update")
        { 
        }
        if (Employee == "Delete")
        { 
        }
        return null;
    }

Answer 1

按钮位于BeginForm() { }块之外，因此未提交Employee数据值（由单击的按钮确定）。

单击按钮时未执行操作方法
