視頻譯叢環陣列

Question

我通過Brightcove公司我的影片引渡陣列試圖循環，並保持上來不成功不管我怎麼努力。

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

此代碼的結果是：

[對象的對象]，[對象的對象]，[對象的對象]，[對象的對象]，[對象的對象]，[對象的對象]

顯示有6個獨立的演繹。

正如你可以從我的控制檯日誌上面複製的文本可見，演繹裏邊有6分不同的人，我想打電話給一個網址的frameWidth = 1248

任何建議？

Answer 1

您只需通過數組循環：

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