我有三个AJAX请求开火了一个又一个，我想能够同时回显所有数据。

I have three AJAX requests firing one after another, and I'd like to be able to echo back all the data simultaneously.

$.ajax ({
        type: "POST",
        url: "page1.php",
        data: "var1=" + var1,
        success: function(msg) {
            $("#results2").load("page2.php", 
            function (responseText, textStatus, XMLHttpRequest) {
                $("#results3").load("page3.php",
                function (responseText, textStatus, XMLHttpRequest) {
                    if (textStatus == "success") {
                        $("#results1").html(msg);
                    }
                });
          });
        }
    });

＃结果1 ，＃结果2 和＃结果3 都需要下载其相对的数据在同一时间。上述code没有这样做。

#results1, #results2 and #results3 all need to be loaded with their relative data at the same time. The above code isn't doing it.

推荐答案

您可以使用推迟对象 jQuery的加入1.5版本：

you can use deferred object of jQuery added in 1.5 version:

$.when( $.ajax({1}) , $.ajax({2}) , $.ajax({3}) )
.then(function() {
  alert("tada");
});
