推荐答案

Ref表示您要保留更改.据我所知，您正在尝试的事情是不可能的.您正在尝试从JavaScript调用服务器方法-这将是无状态调用.您不能以这种方式维护对象.我不确定为什么要尝试做这些事情，但是还有其他方法，例如使用XMLHttpRequest发送数据并在客户端获取想要的内容.

我建议在这里使用XMLHTTPRequest来调用服务器方法并获取数据: XMLHttpRequest [^ ]

Ref means you want to maintain the change. What you are trying is not possible as far I know. You are trying to call a server method from JavaScript - that would a stateless call. You cannot maintain an object this way. I am not sure why are you trying to do such stuff but there can be other ways like using XMLHttpRequest to send the data and get back what you want on client side.

I would suggest using XMLHTTPRequest here for calling a server method and getting back data: XMLHttpRequest[^]
