我在我的页面上添加了一个视差代码，但图像没有出现，当我从图像的容器中删除“视差”类时，图像出现但没有视差效果，

  <div class="parallax-container">
    <div class="parallax"><img src="content/img/wood.jpg"></div>
  </div>
  <div class="section white">
    <div class="row container">
      <h2 class="header">Parallax</h2>
      <p class="grey-text text-darken-3 lighten-3">Parallax is an effect where the background content or image in this case, is moved at a different speed than the foreground content while scrolling.</p>
    </div>
  </div>
  <div class="parallax-container">
    <div class="parallax"><img src="content/img/wood.jpg"></div>
  </div>


<script type="text/javascript">
var elem = document.querySelector('.parallax');
var instance = M.Parallax.init(elem, options);

// Or with jQuery

$(document).ready(function(){
$('.parallax').parallax();
});

</script>

这些是我添加的库

  <script src="app\lib\angular.min.js"></script>
  <script src="app\lib\angular-route.min.js"></script>
  <script src="app\lib\angular-aria.min.js"></script>
  <script src="app\lib\angular-messages.min.js"></script>
  <script src="app\lib\angular-animate.min.js"></script>
  <link rel="stylesheet" href="app\lib\angular-material.min.css">
  <script src="app\lib\angular-material.min.js"></script>
  <link rel="stylesheet" href="content/css/styles.css">
  <!--Materialize-->
  <link href="materialize\css\icon.css" rel="stylesheet">
  <link rel="stylesheet" href="materialize/css/materialize.min.css">
  <link rel="stylesheet" href="app\lib\Roboto.css">
  <script src="app\app.js"></script>
<script type="text/javascript" src="materialize\js\jquery.3.2.1.min.js"></script>
   <script src="materialize\js\materialize.min.js"></script>

您的错误在于尝试在 Javascript 代码中两次初始化该函数。另外（至少在我这边），在初始化组件以实现物化时，我偶尔会在使用 vanilla JS 时收到错误。你可以做什么：（删除原版 JS 代码并将其添加到文件的末尾，最好在正文标记的末尾下方）

<script>
 $(document).ready(function(){
  $('.parallax').parallax();
 });
</script>

确保在物化脚本之前调用 jquery，如下所示：

 <script type="text/javascript" src="materialize\js\jquery.3.2.1.min.js"> 
 </script>
 <script src="materialize\js\materialize.min.js"></script>
