我试图让使用jQuery像这样两个并联的Ajax请求：

I am trying to make two ajax requests in parallel using jQuery like this:

    var sources = ["source1", "source2"];

    $(sources).each(function() {
      var source = this;
      $.ajax({
        async: true,
        type: "POST",
        data: {post: "data", in: "here"},
        url: "/my/url/" + source,
        success: function(data) {
          process_result(data);
        }
      });
    });

我从基本结构this问题，但我的要求还是没有被并行地。 源1需要一段时间才能完成，而且我可以在第二个请求不发，直到第一个完成在服务器上看到的。

I got the basic structure from this question, but my requests still aren't being made in parallel. "source1" takes a while to complete, and I can see on the server that the second request isn't made until the first is completed.

据我所知，我没有任何其他活动的请求，所以我不认为这是与浏览器的并行请求的最大数量的问题。我失去了别的东西吗？

As far as I can tell, I don't have any other active requests, so I don't think it's a problem with the maximum number of parallel requests for the browser. Am I missing something else here?

推荐答案

jQuery的不排队Ajax请求。如果你的确定你没有做任何其他请求最终，怎么样的服务器？也许它只有一个工人？

jQuery does not queue AJAX requests. If you're sure you're not making any other requests your end, how about the server? Maybe it only has one worker?

修改：而只是为了确保，我与启动2 AJAX POST请求，睡5秒一个PHP脚本的脚本进行了测试。他们没有排队。

EDIT: And just to make sure, I tested it with a script that launches 2 AJAX POST requests to a PHP script which sleeps for 5 seconds. They were not queued.
