排序回答：否

龙答：这两个 ajaxComplete 和 ajaxStop 是jQuery的AJAX事件。不能从发生prevent事件 - 与事件是指没有其他的执行已登记的回调函数。回调被调用无论如何，如果你想要或不。

Long answer: Both ajaxComplete and ajaxStop are jQuery AJAX events. You cannot prevent events from happening - and "event" means nothing else as "execute every callback function that has been registered". Callbacks get called regardless, if you want or not.

您的什么的做的是计划中的回调，使得它的没有的时候一定要求（或不能）满足。实际上，这是你问什么了。如果您编辑您的问题来解释你在做什么确切地，人们可以告诉你如何做到这一点。

What you can do is program your callback so that it does nothing when certain requirements are (or are not) met. In effect this is exactly what you asked for. If you edit your question to explain what you're up to exactly, people can show you how to do it.
