在手機中單擊后，按鈕保持聚焦或活動狀態。從而導致發生css影片的問題

我試圖在每次點擊按鈕時獲得影片效果，它在桌面上運行良好，但我在手機上做同樣的事情時遇到問題。我必須單擊一次按鈕，然后在某個空白處失去 css 的焦點狀態，然后再次單擊按鈕以獲得影片效果。

這是代碼片段。

這里也是codepen鏈接。

uj5u.com熱心網友回復：

我希望能夠在影片結束時取消焦點（即模糊），但這不起作用。

這是一個稍微笨拙的解決方法 - 此片段在影片結束時洗掉影片，并在有另一個 touchstart 時將其設定回來。它使用樣式設定而不是類。

let touchDevice = false;
const progBtn = document.querySelector('.prog_btn');
const path = document.querySelector('.prog_btn  .svgStroke path');
path.addEventListener('animationend', function() {
  path.style.animation = '';
});
progBtn.addEventListener('touchstart', function() {
  touchDevice = true;
  path.style.animation = 'dash 1.5s cubic-bezier(0.25, 0.46, 0.45, 0.94)';
});
progBtn.addEventListener('mouseover', function() {
  path.style.animation = 'dash 1.5s cubic-bezier(0.25, 0.46, 0.45, 0.94)';
});
