你如何解除特定命名空间中的所有jQuery事件的绑定？

在jQuery中是否有全局解除绑定功能，以便我能够从给定的命名空间中删除所有绑定的事件？例如：

Is there a "global" unbind function in jQuery, such that I'd be able to remove all bound events from a given namespace? eg:

// assume these are the events bound to different elements
$('#foo').bind('click.myNS', ...);
$('#bar').bind('keyup.myNS', ...);
$('#baz').bind('dblclick.myNS', ...);    

// magic occurs here...
$.magicalGlobalUnbindFunction('.myNS');

// ...and afterwards, the three binds from above are gone

我所看到的所有示例都取消绑定，需要先选择一些元素。我猜，在技术上，你可以做 $（'*'）。unbind（'。myNS'），但这似乎非常效率低下。 / p>

All the examples I've seen for unbind require some elements to be selected first. I guess that technically, you could do $('*').unbind('.myNS'), but that seems very inefficient.
