I would write a client-side JavaScript function that calls a server-side method through an AJAX call (eg through jQuery.ajax() ). 我将编写一个客户端JavaScript函数，该函数通过AJAX调用（例如，通过jQuery.ajax() ）来调用服务器端方法。
The JavaScript function could either be called during page load or through a timer that checks regularly. JavaScript函数可以在页面加载期间调用，也可以通过定期检查的计时器来调用。
