I hope the above information will be helpful. If you have more concerns, please let me know.

我不认为可以直接做您尝试做的事情.服务器端功能位于服务器端，而客户端功能则位于客户端.使任何服务器端代码运行的唯一方法是提交表单. ASP.NET展开HTTP标头，解压缩隐藏的ViewState变量，重新实例化对象，然后根据上述所有决定要引发的事件.

您可以做的是让您的Javascript函数设置一个隐藏的表单变量，然后执行form.submit().

然后在服务器上的Page_Load处理程序中，使用Request对象检查此变量的存在和/或值，然后调用适当的服务器端方法.

希望这可以帮助.我不是专家，但是在搜索您的问题时发现了这种方法.如果有人知道其他方式，也请让我知道.

I don''t thing it is possible to directly do the stuff you are trying. Server-side function live on server-side and the client-side function love on the client. The only way to get any server-side code to run is to submit the form. ASP.NET unrolls the HTTP headers, unpacks the hidden ViewState variable, re-instantiates objects, and then decides what events to raise based on all of the above.

What you can do is have your Javascript function set a hidden form variable, then do a form.submit().

Then in your Page_Load handler on the server, use the Request object to check for the presence and/or value of this variable, and call the appropriate server-side method.

Hope this helps. I am not an expert but I found this way while searching for your question. If anyone knows any other way please let me know too.

听起来像您想知道如何从Javascript与服务器对话.
通过客户端(Javascript)与服务器端进行交互的方法很少:
1. XMLHttpRequest [回调 [ Web服务调用 [ PageMethod [

Sounds like you want to know how to talk to server from Javascript.
There are few ways to interact with server side through client side(Javascript):
1. XMLHttpRequest[^]
2. Callback[^]
3. WebService call[^]
4. PageMethod[^]
