The solution to repeatedly loading the js package

  <script type="text/javascript">
    window.jQuery || document.write("<script src='./../static/libs/jquery/jquery-3.2.1.min.js?ver=1.1'>" + "<" + "/script>");
  </script>

 

 

Load document.write("<script src='./../static/libs/jquery/jquery-3.2.1.min.js?ver=1.1'>" + "<" + "/script >");
