使用 youtube 数据 api 在 iframe 中获取第一个带有分页的视频？

Question

我只想在 iframe 中显示从 youtube 数据 api 和其他缩略图中检索到的第一个视频。第一次加载页面时，第一页的每个页面上显示 10 条记录，但当我点击时它显示正确下一页则不显示第二个插槽的第一个视频

我不知道该怎么做。如果您有任何解决方案，请告诉我

    function tplawesome(template, data) {
    // initiate the result to the basic template
    res = template;
    // for each data key, replace the content of the brackets with the data
    for(var i = 0; i < data.length; i++) {
        res = res.replace(/\{\{(.*?)\}\}/g, function(match, j) { // some magic regex
            return data[i][j];
        });
    }
    return res;

是的，我有这个问题的解决方案。 解决方案是你只需添加这行代码即可解决问题

在 index.php 文件中你必须添加样式标签。

.item{display: none;}

并且在 script.js 文件中你必须编写这行代码

$.get("item.html",function(data){
        $('#results').append(tplawesome(data, [{"title":item.snippet.title,"videoid":item.snippet.resourceId.videoId,"description":item.snippet.description}]));
        $('.item:first').css('display','block');
        //$('#thumbs').append('<div><img id="img_'+item.snippet.resourceId.videoId+'" src="'+item.snippet.thumbnails.default.url+'" height="120" width="90" onclick=show_video("'+item.snippet.resourceId.videoId+'")></div>');
        //$('#thumbs').append('<div><img id="img_'+item.snippet.resourceId.videoId+'" src="'+item.snippet.thumbnails.default.url+'" height="120" width="90" onclick=show_video("'+item.snippet.resourceId.videoId+'")><h3 style="float: right;padding-right: 100px;">'+item.snippet.title+'</h3></div>');
        $('#thumbs').append('<div><img id="img_'+item.snippet.resourceId.videoId+'" src="'+item.snippet.thumbnails.default.url+'" height="120" width="90" onclick=show_video("'+item.snippet.resourceId.videoId+'")><div style="float: right;"><h2 style="padding-left: 10px;font-size: 18px;">'+item.snippet.title+'</h2></div><div style="margin-top:-72px;margin-left: 179px;"><h5 style="font-size: 16px;">'+item.snippet.description+'</h5></div><div style="margin-left:176px;margin-top: -14px;padding-top: 3px;padding-left: 4px;"><h5 style="font-size: 14px;margin-top: -5px;">Total Views: <span id=view_'+item.snippet.resourceId.videoId+'></span></h5></div></div>');
        getcount(v_id);

        });
