Web开发：如何从嵌入式C代码到javascript访问变量？

Question

I'm new to web development and I'm using AppWebServer to AppWeb to host my website. AppWeb provides ESP (Embedded Server Pages) that is used to create web applications. You may embed a C code.

Now my problem is. I have a javascript code and a C Code, I need to access a variable from the C code and use it in javascript, the question is how do I do that?

I am thinking that even if I declare the variable as global, I wont still be able to access.

您可以使用HTML创建隐藏的输入类型，并用<input type="hidden" id="something" value <%=function in c that returns your variable%>" />插入所需的变量，然后访问它使用您的JavaScript使用getElementById("something")
