Google AMP - 故事

amp-story 是一個 amp 元件，用於顯示內容，讓使用者參與到故事中。例如，使用一系列圖片講述一個品牌的的故事。

要使用 amp-story，我們需要包含如下所示的指令碼：

<script async custom-element = "amp-story" 
   src = "https://cdn.ampproject.org/v0/amp-story-1.0.js">
</script>

在本章中，讓我們瞭解什麼是 amp-story 以及它是如何工作的。假設我們有一個圖片庫，並希望在頁面上顯示它。在 amp 頁面中，我們可以使用 amp-story 元件使它對使用者看起來更美觀和互動。

amp-story 標籤的格式如下所示：

<amp-story standalone> ---> Main story Tag
   <amp-story-page id = "page-1"> ---> Pages inside the story e.g page1
      <amp-story-grid-layer template = "fill"> --> 
         Layers for the page1.You can have more than one layer.
         //Add html elements here or amp components
      </amp-story-grid-layer>
      <amp-story-grid-layer template = "fill"> --> 
         Layers for the page1.You can have more than one layer.
         //Add html elements here or amp components
      </amp-story-grid-layer>
      ...
   </amp-story-page>

   <amp-story-page id = "page-2"> ---> Pages inside the story e.g page2
      <amp-story-grid-layer template = "fill"> --> 
         Layers for the page2.You can have more than one layer.
         //Add html elements here or amp components
      </amp-story-grid-layer>
      ...
   </amp-story-page>
   ...
</amp-story>

amp-story 還有一些額外的屬性，如下所示：

<amp-story standalone title = "My Story"
   publisher = "The AMP Team"
   publisher-logo-src = "publisherlogo image here"
   poster-portrait-src = "poster portrait here"
   poster-square-src = "poster square image here"
   poster-landscape-src = "poster landscape image here">

此功能使使用 amp 講故事變得非常互動。

以下程式碼顯示了 amp-story 的一個工作示例。桌面和移動模式下的輸出也顯示了出來。

桌面輸出

這就是故事部分的顯示方式。您還可以新增影片或任何其他 amp 元件，使故事更具互動性。

到達故事結尾時，它將顯示 amp-bookend 中給出的內容，如下所示：

<amp-story-bookend 
   src = "ampstory.json" layout = "nodisplay">
</amp-story-bookend>

我們向 amp-bookend 提供了一個 ampstory.json 檔案。json 檔案包含下一個故事預覽的詳細資訊，如下所示。當用戶點選右側顯示的三個點時，將顯示以下螢幕：

它提供了一個重播按鈕，該按鈕將重新載入故事。您可以點選汽車的圖片，它將顯示汽車品牌的故事。

移動模式下的輸出如下所示：
