How to read cookie in view MVC3?
提问by Nguy?n Tr?ng B?ng
I have a list of comment objects in the view. Each comment has one cookie that mark the status from user action. Example: like, spam,...
我在视图中有一个评论对象列表。每条评论都有一个 cookie，用于标记用户操作的状态。例如：喜欢，垃圾邮件，...
In the view, I want to read the corresponding cookie of each comment to display the right view to user. Example: user A who liked comment B then the view will display the unlike button
在视图中，我想读取每个评论的相应cookie，以向用户显示正确的视图。示例：用户 A 喜欢评论 B 然后视图将显示不同按钮
I don't want to read cookie in the controller because the return data is a list of comment objects.
我不想在控制器中读取 cookie，因为返回数据是一个注释对象列表。
