我正在尝试在 Brightcove 中循环播放我的视频的演绎数组，并且无论我尝试什么都失败了。

document.getElementById('divMeta.render').innerHTML = v.renditions;

这段代码的结果是：

[对象对象],[对象对象],[对象对象],[对象对象],[对象对象],[对象对象]

显示有 6 个单独的演绎版。

正如您在从上面的控制台日志中复制的文本中看到的那样，在再现中有 6 个不同的，我想调用 frameWidth = 1248 的 url。

有什么建议么？

您可以循环遍历数组：

var url;
for (var i = 0; i < v.renditions.length; i++) {
    if (v.renditions[i].frameWidth == 1248) {
        url = v.renditions[i].url;
        break;
    }
}
