显示图库图像时需要有关 Flickr/JSON/Javascript 问题的帮助

Question

想知道是否有人可以帮助我。我试图通过从 Flickr 画廊中提取照片来整理每周的照片竞赛页面，但我无法显示图像。对于团体来说它工作正常，但画廊代码有一些问题。获取正确的 JSON 响应，但无法像组图像一样在页面上显示结果。

这是我的 Javascript：

$(function() {

    var map;
    var markers = [];
    var infowindow;

    // Get gallery photos
    var visibleGallery;

    $.getJSON("http://api.flickr.com/services/rest/" + 
"?method=flickr.galleries.getPhotos" +
"&api_key=XXXX" + 
"&photoset_id=XXXX" +
"&extras=geo,tags,url_sq,url_t,url_s,url_m,url_o" +
"&format=json&jsoncallback=?", function(data, textStatus) {

            var htmlString = '<div id="weekContainer">';

            var weeks = sortIntoWeekArrays(data.photos.photo);

            $.each(weeks, function(i, week)
            {
                    var weekNumber = i + 1;
                    var numberOfWeeks = weeks.length - 1;

                    htmlString += '<div id="week' + weekNumber + '">';
                    htmlString += '<ul class="weeks">';
                    if(i < numberOfWeeks)
                    {
                            htmlString += '<li><a class="weekLinksNext" href="#"><span>Next</span></a></li>';
                    }

                    var sunday = new Date(week.monday.toUTCString());
                    sunday.setDate(week.monday.getDate() + 6);
                    htmlString += '<li class="weekTitle">Week ' + weekNumber + ':</li><li class="weekDate"> ' + week.monday.format("ddd d mmm") + ' &mdash; ' + sunday.format("ddd d mmm") + '</li>';
                    if(i > 0)
                    {
                            htmlString += '<li><a class="weekLinksPrev" href="#"><span>Previous</span></a></li>';
                    }
  htmlString += '</ul>';

                    if(week.winner !== undefined)
                    {
                            htmlString += '<p class="galleryTitleFirst">Photo of the Week</p>';
                            htmlString += '<ul class="imagesWinners">';

}

任何帮助都会很棒:)

经过朋友的帮助才搞定。我在 extras 参数中缺少 date_upload 值，并且 item.dateadded 需要更改为 item.upload。
