javascript - 分割 youtube 视频 url

Question

我需要从 youtube 视频网址获取 id。我正在使用 split 方法，但在控制台中它给出以下错误

Uncaught TypeError: Cannot read property 'split' of undefined

我的视频网址是: https://www.youtube.com/embed/juIJGBxj-4w

我的代码是

id = url.split('/')[1].split('embed')[1];

Answer 1

The regular expression will extract the video ID from any YouTube URL and it works with shortened URLs (youtu.be) and embed URLs (youtube.com/embed/) as well.

 function extractVideoID(url){
        var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
        var match = url.match(regExp);
        if ( match && match[7].length == 11 ){
            return match[7];
        }else{
            alert("Could not extract video ID.");
        }
    }
