YouTube視頻ID的正則表達式

我有以下代碼檢測字符串中的視頻ID。它實際上捕捉到更多的情況下，我需要，我想使它更簡單，在此格式只對字符串返回ID：YouTube視頻ID的正則表達式

https://www.youtube.com/watch?v=85PMSYAguZ8 
https://youtu.be/85PMSYAguZ8

代碼：

_getVideoIdFromUrl: function (value) { 
var regEx = /^(?:https?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v=|watch\?.+&v=))((\w|-){11})(?:\S+)?$/; 
var matches = value.match(regEx); 
if (matches) { 
    return matches[1]; 
} 
return false;

}，

我需要幫助來相應地更改regEx，任何想法？

目前檢測：

聽起來是個好主意，請你給我一個簡單的例子，我不是很熟悉的正則表達式。 – Radex

這是一個非常非常基本的正則表達式。 '的https：//（：萬維網\ .youtube \的.com /觀看\ V = | youtu \ .BE /？）（[\ W-] {11}）'。 –

試試這個：

我會做這樣的事情：
它讓你指定所有實例的視頻ID

const urls = ['http://www.youtube.com/watch?v=cKZDdG9FTKY&feature=channel',
