将数据从本地应用程序推送到浏览器

I have C++ application to monitor local computer and a HTML5 webpage (offline support) to show statistics. At present my application send data through server to webpage, but it works only on online. Now I want to support full offline mode, so I need to push data directly to webpage to fire javascript events. Is this possible? And is this possible on cross-platforms?
