Question

我关注/复制了所有可用内容here。但是当我点击链接按钮时，灰色背景（叠加）显示，但模态本身就丢失了。

不同浏览器中的行为：

Chrome 53.0 叠加显示，模态未显示

Mozilla 18.0，IE 11.0，Opera 42.0 叠加显示，模态显示不到一秒然后消失

检查开发人员工具/开发人员菜单/开发人员工具栏表示模式应该可见。以下是供参考的标签：

按钮链接 删除了示例中的类以维护链接设计

<a href="#modal1">Modal</a>

页面加载时的模式

<div id="modal1" class="modal">
<!-- contents same with the sample located at http://materializecss.com/modals.html#structure -->
</div>

点击按钮链接上的模式 悬停时，屏幕上的高亮显示也不可见

<div id="modal1" class="modal open" style="z-index: 1003; display: block; opacity: 1; transform: scaleX(1); top: 10%;">

关闭模式

<div id="modal1" class="modal" style="z-index: 1003; display: none; opacity: 0; transform: scaleX(0.7); top: 100px;">

单击按钮链接上的叠加

<div class="modal-overlay" id="materialize-modal-overlay-1" style="z-index: 1002; display: block; opacity: 0.5;"></div>

初始化的脚本 位于body元素的末尾

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

我该如何解决这个问题？有没有办法知道问题是什么？

将modal移到navbar之外，它会正确显示。

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

我没有看到演示代码有任何问题。请检查一下片段，也许你错过了一些图书馆？

如果您使用cdn，请确保所有库已成功加载。

或者您应该检查图书馆的导入顺序。例如，必须在jQuery

之前加载materialize

物化模式不显示
