谁能提供amp-accordion 的工作示例？当我在引用
<script async custom-element="amp-accordion" src="https://cdn.ampproject.org/v0/amp-accordion-0.1.js"></script>
在标题中，我收到以下两条（令人不安的）错误消息：
The attribute 'custom-element' in tag 'amp-access extension .js script' is set to the invalid value 'amp-accordion'. (see https://www.ampproject.org/docs/reference/extended/amp-access.html)
最后
The tag 'amp-accordion' is disallowed.
有什么想法吗？

标签： amp-html
在 head 标签内添加amp JS 和amp accordion JS，如下所示
<!--
## Introduction
An accordion provides a way for viewers to have a glance at the outline of the content and jump to a section or their choice at their will.

【讨论】：
虽然它是实验性的，但有必要启用它。请注意，仅 toggleExperiment 是不够的，您需要检查该实验是否尚未启用。请参见下面的示例。
<script async custom-element="amp-accordion" src="https://cdn.ampproject.org/v0/amp-accordion-0.1.js"></script>
<script>
(window.AMP = window.AMP || []).push(function(AMP) {
if(!AMP.isExperimentOn('amp-accordion'))
AMP.toggleExperiment('amp-accordion');
});
</script>
别忘了为它添加样式：
<style amp-custom>
section[expanded] span.expanded {
display: block;
}
section[expanded] span.collapsed {
display: none;
}
section:not([expanded]) span.expanded {
display: none;
}
section:not([expanded]) span.collapsed {
display: block;
}
</style>
【讨论】：
According to this page，它似乎是一个实验性组件，必须是 manually enabled here 并且在控制台中使用以下 javascript 行：
AMP.toggleExperiment('amp-accordion')
【讨论】：
type 是除必需值之外的任何值时：application/json。当脚本标签的src 属性无效时也会抛出错误。
