Silverlight:如何禁用浏览器的刷新按钮？

Question

我正在开发 Silverlight 应用程序(即根本没有 HTML 内容)，最大的提示之一是，如果用户不小心按 F5，应用程序会重新启动。

那么有什么办法可以禁用浏览器中的刷新按钮吗？或者至少处理F5？

One option is to hook into the window object 'onbeforeunload' event and prompt the user to confirm the refresh/exit intent. Here is a simple example that could be defined in your HTML markup or even emitted from the SL app (if it has DOM access):

<script type="text/javascript">
window.onbeforeunload = function() {
    return "Leaving or refreshing this page can result in data loss.";
}
</script>
