ReferenceError: D:\nodejs\crud\views\employee\addOrEdit.ejs:8

Question

您好，我正在尝试使用ejs作为视图引擎来编辑nodejs中的数据，但它显示: D:\nodejs\crud\views\employee\addOrEdit.ejs:8，：ReferenceError how to ReferenceError，、，

通过点击下面的链接，我将进入编辑页面：

  <a href="/employee/<%= this.id %>" class="btn btn-outline-warning my-2 my-sm-0">Edit</a>

在编辑页面上，我得到了这个：

    ReferenceError: D:\nodejs\crud\views\employee\addOrEdit.ejs:8
      6|       </h1>

      7|       <form action="/employee" method="POST">

   >> 8|         <input type="hidden" name="id" value="<%= employee.id %>">

      9|         <div class="form-group">

      10|           <label for="name">Fullname</label>

      11|           <input
