<video id="video" autoplay="True" height="480" width="640">定義一個按鈕 <button id="restart" type="button" >重新開始</button>js部分：var v = document.getElementById('video');function restart(){v.currentTime=20;}var restart = document.getElementById('restart')restart.addEventListener('click',function(){restart(v)})不起作用啊，點擊重新開始按鈕沒反應，請問哪里有問題？謝謝
