我正在使用for循环在我的 HTML 表中追加多行jquery。

for循环（下面的代码）在ajax返回的调用响应上运行array of arrays。但无论否，只有 1 行被添加到表中。数组中的元素。

实际的响应对象非常大，所以我附上一个Google Drive 链接以供参考

如何追加表中的所有行？

代码片段（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++) {

if (data && data.OTA_AirLowFareSearchRS && data.OTA_AirLowFareSearchRS.PricedItineraries && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v] && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].AirItinerary && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].AirItinerary.OriginDestinationOptions && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].AirItinerary.OriginDestinationOptions.OriginDestinationOption[b] && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].AirItinerary.OriginDestinationOptions.OriginDestinationOption[b].FlightSegment && data.OTA_AirLowFareSearchRS.PricedItineraries.PricedItinerary[v].AirItinerary.OriginDestinationOptions.OriginDestinationOption[b].FlightSegment[m]) {
    // Build row using nested JSON
}

更正了 JSFiddle

PS 要快速调试，您必须始终检查browser console以查找任何 JSON 异常。几乎 90% 的问题都可以通过显示的错误字符串得到解决。为了理解真正的问题，我做了同样的事情:)
