no, but you can put the value into hidden field and access it from js.
不，但您可以将值放入隐藏字段并从 js 访问它。
or you can make server method and call it from JS.
或者你可以制作服务器方法并从JS调用它。

That variable doesn't exist in JavaScript because it is running on a different machine than the C# code. C# is running on the server and JavaScript is running on the client's browser.
该变量在 JavaScript 中不存在，因为它运行在与 C# 代码不同的机器上。C# 在服务器上运行，JavaScript 在客户端的浏览器上运行。
Have your page write the property out either to a dynamically generated javascript var or to an HTML hidden field.
让您的页面将该属性写入动态生成的 javascript var 或 HTML 隐藏字段。
