(我正在使用videojs播放器。我创建了自定义按钮组件，并在播放器的左上角添加了该按钮。我使用电视遥控器控制所有按钮。当我从playToggle按钮转到左上角的自定义标题按钮时遇到问题。自定义按钮变得可聚焦，但在控制台中显示以下错误。)

VIDEOJS: ERROR: TypeError: Cannot read property 'getChild' of undefined at t.

(VIDEOJS：错误：TypeError：无法读取t处未定义的属性“ getChild”。)

(VM624 index.min.js:1) at HTMLButtonElement.i.dispatcher (VM624 index.min.js:1)

(HTMLButtonElement.i.dispatcher上的（VM624 index.min.js：1）（VM624 index.min.js：1）)

I consoling below code, console.log(player.getChild("controlBar").getChild("ExtendedControlBar").getChild("ToggleCaption"));

(我安慰下面的代码，console.log（player.getChild（“ controlBar”）。getChild（“ ExtendedControlBar”）。getChild（“ ToggleCaption”））;)

(打印正确的数组，但抛出错误。)
