</div>

使用这个 html 代码和这个脚本

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
 function updateTextArea() {     
 var allVals = [];
 $('.taglist :checked').each(function(i) {

   allVals.push((i!=0?"\r\n":"")+ $(this).val());
 });
 $('#video0_tags').val(allVals).attr('rows',allVals.length) ;

 }
 $(function() {
  $('.taglist input').click(updateTextArea);
  updateTextArea();
 });
</script>
