forloop中实施ajax

forloop中执行ajax

  var imgs = document.querySelectorAll(".obj");

            for (var i = 0; i < imgs.length; i++) {

                data = imgs[i].value;

                $.ajax({

                    type: "POST",

                    url: "ajax.ashx",

                    data: { data: data },

                    beforeSend: function() {

                        $("#image1").css("display", "inline");

                    }

                })

                 .done(function(data) {

                     if (data == 1 || data == "1") {

                         var result = $("<p>Successful</p>");

                         $('#fileList').append(result);

                     }

                     else {

                         var result = $("<p>upload fail</p>");

                         $('#fileList').append(result);

                     }

                     $("#image1").css("display", "none");

                 })

                 .fail(function() { alert("error"); });

                $("#image1").css("display", "none");

            }

这样子好像是同时发送多个ajax请求 ，我想让他完成了一次请求才继续运行 forloop ，不知道要怎么写 ！ 高手指导一下我吧 ，万分感激 ！
