【问题描述】：

我最近开始使用 materializecss 制作网站。一切都很顺利，除了我无法让可折叠设备正常工作。它们出现在我的网站上，但根本无法点击。我已经导入了所有的 css 和 js 文件，但这似乎没有帮助。

<html>
    <head>
    <link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
    <link type="text/css" rel="stylesheet" href="css/materialize.min.css"  media="screen,projection"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    </head>

    <body>
        <ul class="collapsible">
            <li>
            <div class="collapsible-header"><i class="material-icons">filter_drama</i>First</div>
            <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
            </li>
            <li>
            <div class="collapsible-header"><i class="material-icons">place</i>Second</div>
            <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
            </li>
            <li>
            <div class="collapsible-header"><i class="material-icons">whatshot</i>Third</div>
            <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
            </li>
        </ul>


    <script type="text/javascript" src="js/materialize.min.js"></script>
    </body>
</html>

<script src="https://code.jquery.com/jquery-2.1.1.min.js"></script>

我得到了所有的样式表和脚本，我需要做什么？

【解决方案1】：

问题是你还没有初始化 collapsible 这就是它不起作用的原因。

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

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/css/materialize.min.css" />

<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>

<ul class="collapsible">
    <li>
        <div class="collapsible-header"><i class="material-icons">filter_drama</i>First</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
    <li>
        <div class="collapsible-header"><i class="material-icons">place</i>Second</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
    <li>
        <div class="collapsible-header"><i class="material-icons">whatshot</i>Third</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
</ul>

非常感谢！它起作用了
我相信真正的问题是你需要在 before materialize.js 之前加载 jquery.js

【解决方案2】：

您需要添加Initialization step:

document.addEventListener('DOMContentLoaded', function() {
   var elems = document.querySelectorAll('.collapsible');
   var instances = M.Collapsible.init(elems, {accordion: false});
});

使用 jQuery：

$('.collapsible').collapsible();

document.addEventListener('DOMContentLoaded', function() {
    var elems = document.querySelectorAll('.collapsible');
    var instances = M.Collapsible.init(elems, {accordion: false});
});

<ul class="collapsible">

        <div class="collapsible-header"><i class="material-icons">filter_drama</i>First</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
    <li>
        <div class="collapsible-header"><i class="material-icons">place</i>Second</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
    <li>
        <div class="collapsible-header"><i class="material-icons">whatshot</i>Third</div>
        <div class="collapsible-body"><span>Lorem ipsum dolor sit amet.</span></div>
    </li>
</ul>
