AMP：amp-accordion 不工作

Question

任何人都可以提供 amp-accordion 的工作示例吗？当我在引用

的 amp 页面中尝试来自 https://www.ampproject.org/docs/reference/extended/amp-accordion.html 的示例代码时

<script async custom-element="amp-accordion" src="https://cdn.ampproject.org/v0/amp-accordion-0.1.js"></script>

在 header 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？

Answer 1

According to this page, it seems to be an experimental component and has to be manually enabled here 并在控制台中使用以下行 javascript:

AMP.toggleExperiment('amp-accordion')

Answer 2

虽然它是实验性的，但有必要启用它。请注意，仅仅 toggleExperiment 是不够的，您需要检查实验是否尚未启用。请参阅下面的示例。

<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>

另外不要忘记为其添加样式：

   <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>

在 head 标签内添加 amp JS 和 amp accordion JS

<!--
  ## 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.
