你可以像这样使用它

function changevideo() {
var e=document.querySelector('#url1').value;
console.log(e)
  document.getElementById('video1').setAttribute('src', e)
  }

<input class="url" id="url1" type="url" value="youtube url">
<input onclick="changevideo()" class="add-video" id="add-video1" type="submit" value="add to playlist">
<iframe class="video" id="video1"></iframe>
