推荐答案

集线器具有方法disconnect，当断开连接时，该方法将允许您添加回调:

A hub has a method disconnect which will allow you to add a callback when disconnection takes place:

myHub.disconnect(function() {
  alert('Server has disconnected');
});

如果您不使用集线器，则断开连接方法的代码将为您提供帮助:

If you aren't using hubs then the code for the disconnect method will help you out:

$(connection).bind("onDisconnect", function (e, data) {
  callback.call(connection);
});

这显示了挂钩到基础连接的onDisconnect事件的语法.

This shows the syntax for hooking onto the onDisconnect event of the underlying connection.
