如何使用jquery从jsp中检索数据？我创建了一个基本表单，然后将值存储到mysql数据库中。然后我使用jsp.Now检索数据库值。我希望我的jquery从jsp代码中获取这些值并打印这些值。这是我的jsp代码

<body style="background-color:#663366">
  <div class="container">
    <br />
    <div class="jumbotron">
      <h1>Authentica</h1>
      <p>Have an account already? Then login</p>
    </div>
    <form class="form-horizontal" action="newjsp.jsp" method="GET">
      <div class="form-group">
        <label class="control-label col-sm-2" for="email" style="color:#FFFFFF">Email:</label>
        <div class="col-sm-3">
          <input type="email" class="form-control" name="vlemail" id="lemail" placeholder="Enter email" />
        </div>
