jQuery的限制同时AJAX请求数 [英] jQuery Limit The Number Of Simultaneous AJAX Requests

问题描述

让我有一系列的AJAX事件，我想火，但我想同时请求的数量限制为5，而排队的其余部分。因此，例如，我有以下几点：

so I have a series of AJAX events I would like to fire, but I want to limit the number of simultaneous requests to 5, and queue up the rest. So for example, I have the following:

 $("div.server").each(function() {
     $.ajax(....);
 });

所以有可能是100的div类服务器，但我想只能运行在任何特定时间5的请求。一旦请求完成后，应该进入下一个。

So there may be 100 divs with the class server, but I want to only run 5 requests at any given time. Once a request finishes it should proceed to the next.

什么是做到这一点的最好方法是什么？

What is the best way to do this?

推荐答案

要做到这一点是让浏览器处理它的最好方法。通常的浏览器已经拥有了每个主机连接的限制，使他们自动排队连接，如果有太多的。

The best way to do this is letting the browser deal with it. Usually browsers already have a per-host connection limit so they will automatically queue connections if there are too many.

不过，我会考虑更改API，因此它需要时间，从多个元素，并返回数据的多个元素 - 即减少必要的HTTP请求的整体计数

However, I'd consider changing the API so it takes date from multiple elements and also returns data for multiple elements - i.e. reducing the overall count of HTTP requests necessary.
