用jQuery追加HTML表中的行不起作用

Question

我正在使用for循環使用jquery在HTML表中追加多行。

for循環（下面的代碼）在ajax調用的響應上運行，該調用返回一個array of arrays 。 但是，無論是否行，只有1行會被添加到表中。 數組中的元素。

實際的響應對象很大，因此我附上了Google雲端硬盤鏈接以供參考

如何追加表格中的所有行？

代碼段（使用Jquery）

$(document).ready(function() {
            $('#ghsubmitbtn').on('click', function(e) {

                var data = JSON.stringify(JSONObj);

                $.ajax({
                    url: 'https://api-crt.cert.havail.sabre.com/v4.2.0/shop/flights?mode=live&limit=50&offset=1',
                    method: 'POST',
                    contentType: "application/json; charset=utf-8",
                    data: data,
                    headers: {
                        "Authorization": 'Bearer ' + bat
                    },

                    success: function(data) {
                        var BookBtn = '<input type="submit" value="Book" name="book" class="btn btn-primary">';

                        for (var v = 0; v <= 999; v++) {
                            for (var b = 0; b <= 999; b++) {
                                for (var m = 0; m <= 999; m++) {

                                    var row = $('<tr><td>' + data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].SequenceNumber + '</td><td>' +

PS要快速調試，您必須始終檢查browser console以查找任何JSON異常。 通過顯示的錯誤字符串，幾乎可以解決90％的問題。 為了理解真正的問題，我做了同樣的事情:)
