Question

我有一个场景，我需要从Web服务API获取500并将最终输出值显示为逗号分隔值，如id，name，owner，account，path，ccvalues。为了实现这一点，我正在编写一个方法，我可以获取所有这些信息并设置为一个java对象。字段在下面。最后，我创建了一个包含此Video对象的列表。 videos.add（视频）

String identifier;
String name;
String ownerName;
String accountName;
String mediaPath;
List<KalturaLanguage> ccList;

现在如何显示视频列表对象的输出。请帮我解决这个问题。

代码是：

for (String mediaId : mediaList) {
                    if (mediaId != null) {
                        String mediaFullPath = getMediaPath(mediaId);
                        entryInfo = getMedia(mediaId);
                        metadataList = getMetadata(mediaId);
                        ccs = getClosedCaptions(mediaId);
                        if (entryInfo != null) {
                            video = new Video();
                            System.out.println("entryInfo.id"
                                    + entryInfo.id);
                            System.out.println("entryInfo.name"
                                    + entryInfo.name);
                            System.out.println("mediaFullPath"
                                    + mediaFullPath);
                            video.setIdentifier(entryInfo.id);
                            video.setName(entryInfo.name);
                            video.setMediaPath(mediaFullPath);
                        }

                        if (metadataList != null
                                && metadataList.totalCount != 0) {
                            List<KalturaMetadata> metadataObjs = metadataList.objects;
                            if (metadataObjs != null
                                    && metadataObjs.size() > 0) {
                                for (int i = 0; i < metadataObjs.size(); i++) {
                                    KalturaMetadata metadata = metadataObjs
                                            .get(i);
                                    if (metadata != null) {
                                        if (metadata.xml != null) {
                                            metadataValues = parseXml(metadata.xml);
                                            if (metadataValues.size() != 0) {
                                                ibmAccountList = metadataValues
                                                        .get(0);
                                                for (String account : ibmAccountList) {

                                                                    + owner);
                                                    video.setOwnerName(owner);

你走错了方向。只需在(function($) { //your model var urls = { isuzu: "https://www.direct4x4.co.uk/catalog/category/view/s/d-max-2012-onwards-canopies-hard-tops-accessories/id/17174/*_blank", ford: "https://www.direct4x4.co.uk/catalog/category/view/s/ranger-t6-2012-canopies-hard-tops-onwards/id/17175/*_blank", nissan: "", mitsubishi: "", toyota: "", vw: "", } //updating the currentUrl var currentUrl = ""; $("#select").on("change", function(e) { var val = $("#select").find('option:selected').attr("value"); currentUrl = urls[val]; }); $("#myForm").on("submit", function(e) { e.preventDefault(); console.log(currentUrl); window.open(currentUrl); }); }(jQuery));类中实施toString方法。

当您遍历列表并打印视频对象时，它会在视频类中调用Video方法。

在视频类中提供实现时，生成所需格式的字符串。
