我將如何在點擊時更改播放 svg 顏色，它會停留在哪里并且不會變回之前的顏色？
它將如何作業：
我單擊 svg，打開視頻，單擊主頁按鈕。
Home鍵是X
之前單擊的 svg 按鈕現在的顏色與以前不同。
這就是我正在努力做的。

我編輯了具有addClickToButtons如下功能的行，它對我有用：
function addClickToButtons(playButtons) {
playButtons.forEach(function addHandler(playButton) {
playButton.addEventListener("click", (e) => {
coverClickHandler(e);
playButton.style.fill = 'white';
});
});
}
