滚动窗口然后div，jQuery

Question

我正在努力编写代码，这让我像示例中一样获得效果。我之所以这样做，是因为Scrollintoview仅在Chrome中正常工作。https://jsfiddle.net/lw6b88wg/1/

btn.onclick = function() {
    let listElements = document.querySelectorAll('p');
    let lastElementNumber = listElements.length;
    listElements[lastElementNumber - 1].scrollIntoView({
        behavior: 'smooth',
        block: 'end',
        inline: 'end'
    });
}

Answer 1

$('#btn').on('click', function() {
  var divHeight = $('#outer-div')[0].scrollHeight;
  $('html, body').animate({
    scrollTop: '0px'
  }, 300);
  $('#outer-div').animate({
    scrollTop: divHeight
  }, 300);
});

body {
  height: 1500px;
  position: relative;
  margin: 0;
  padding-bottom: 6rem;
}
div {
  border: 1px solid red;
  overflow-y: scroll;
  width: 100px;
  height: 200px;
}
button {
  position: absolute;
  bottom: 0;
  left: 0;
}

<div id="outer-div">
