Google AMP - Timeago

Timeago 将通过与过去(例如"x"小时前)进行比较来提供时间戳详细信息。在本章中，我们将详细讨论此功能。

要将此功能插入我们的工作中，我们需要将下面给出的脚本添加到 .html 页面 −

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

amp-timeago 标签如下所示 −

<amp-timeago layout = "fixed" width = "160" height = "20" 
   datetime = "2018-10-01T00:37:33.809Z"
   locale = "en">Monday 01 October 2018 00.37 
</amp-timeago>

让我们借助下面所示的工作示例来理解这一点 −

示例

      <link rel = "canonical" href = " http://example.ampproject.org/article-metadata.html">

      <meta name = "viewport" content = "width = device-width,minimum-scale = 1,initial- scale = 1">

            -animation:none;animation:none
         }
         </style>
      </noscript>

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

      <amp-timeago 
         layout = "fixed" 
         width = "160"
         height = "20"
         datetime = "2018-10-01T00:37:33.809Z"
         locale = "en">Monday 01 October 2018 00.37
      </amp-timeago>
   </body>
</html>

输出

上述代码的输出如下所示 −

如果需要更改"X 时间前"显示，我们可以将"cutoff"属性与 timeago 结合使用。Cutoff 以秒为单位获取值以摆脱显示。

让我们借助下面给出的工作示例来理解这一点 −
