这个js问题应该回答什么？

Question

问题：请创建一个工具来生成添加

rd

预期使用方式：

<?php 
     $file = 'BinarySearch.pdf';
     $filename = 'BinarySearch.pdf';
     header('Content-type: application/pdf');
     header('Content-Disposition: inline; filename = "' .$filename . '"');
     header('Content-Transfer-Encoding: binary');
     header('Accept-Ranges: bytes');
     @readfile($file);
?>

在另一个模块中：

{% for comment in comments %}
<li contenteditable = "TRUE" >{{comment.text}}
<form contenteditable = "FALSE"  action = "{% url 'clickedaccept' %}" method = "POST">
{% csrf_token %}
               <input type = "hidden" name = "acceptedvalue" value = "{{comment.id}}">

             <input type = "hidden" name = "selected_option" value = "{{selected_option}}">

            <input type = "hidden" name = "selected_autocomplete" value = "{{selected_autocomplete}}">

              <input type = "submit" value = "Accept" id = "{{comment.id}}" >
      </form>
{% endfor %}
</li>
