bootstrap滑门鼠标点击改为悬停

bootstrap4的滑门tab点击切换是默认的，如何改成经过悬停切换，其实可以通过js代码实现.
把下面代码加入即可实现了

<script>
$("#myTab a").mousemove(function (e) {
  $(this).tab('show');
});
</script>

<ul class="nav nav-tabs" id="myTab" role="tablist">
<li class="nav-item">
  <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
</li>
<li class="nav-item">
  <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
</li>
<li class="nav-item">
  <a class="nav-link" id="contact-tab" data-toggle="tab" href="#contact" role="tab" aria-controls="contact" aria-selected="false">Contact</a>
</li>
 </ul>
 <div class="tab-content" id="myTabContent">
<div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
<div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
<div class="tab-pane fade" id="contact" role="tabpanel" aria-labelledby="contact-tab">...</div>
 </div>
