问题描述
基本上就是这个问题(括号很重要)
Basically that's the question (parentheses are important)
推荐答案
.ajaxStart() 和 .ajaxStop() 用于 all请求一起，ajaxStart 在 第一个同时请求开始时触发，ajaxStop 触发，然后最后同时批处理结束.
.ajaxStart() and .ajaxStop() are for all requests together, ajaxStart fires when the first simultaneous request starts, ajaxStop fires then the last of that simultaneous batch finishes.
假设您一次发出 3 个请求，ajaxStart() 在第一个请求开始时触发，ajaxStop() 在最后一个请求(他们不不一定按顺序完成)回来.
So say you're making 3 requests all at once, ajaxStart() fires when the first starts, ajaxStop() fires when the last one (they don't necessarily finish in order) comes back.
这些事件没有获得任何参数，因为它们是针对一批请求的:
These events don't get any arguments because they're for a batch of requests:
.ajaxStart( handler() )
.ajaxStop( handler() )
.ajaxSend() 和 .ajaxComplete() 在发送/完成时每个请求触发一次.这就是为什么这些处理程序被传递参数而全局/批处理程序不是:
.ajaxSend() and .ajaxComplete() fire once per request as they send/complete. This is why these handlers are passed arguments and the global/batch ones are not:
.ajaxSend( handler(event, XMLHttpRequest, ajaxOptions) )
.ajaxComplete( handler(event, XMLHttpRequest, ajaxOptions) )
对于单个文档源，全局 Ajax 事件 API 的部分是您所追求的.
For a single documentation source, the Global Ajax Events section of the API is what you're after.
