Question

我让我的客户端在文档周围拖动一个div。但是我无法禁用残像和X标志，我不希望它显示任何额外的东西。

我找到的唯一方法是

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <!-- Latest compiled and minified Bootstrap CSS -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">

  </head>
  <body> 
    <nav class="navbar navbar-default">
      <div class="container-fluid">
      <!-- Brand and toggle get grouped for better mobile display -->
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="index.html"><img src="http://entropymag.org/wp-content/uploads/2014/10/outer-space-wallpaper-pictures.jpg" height="25" width="40"></a>
      </div>

      <!-- Collect the nav links, forms, and other content for toggling -->
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">


        <ul class="nav navbar-nav navbar-center">
          <li><a href="about.html">About</a></li>
          <li><a href="contact.html">Contact</a></li>
          <li><a href="resume.html">Skills</a></li> 

        </ul>
      </div><!-- /.navbar-collapse -->
      </div><!-- /.container-fluid -->
    </nav>
  </body> 
</html>

哪个会摆脱X，但是后映像仍然存在，并且没有必要为此添加一个eventlistener。

我读了其他问题，但他们都想摆脱拖延事件

有什么建议吗？请
