Google AMP - Next Page

Previous Page
Next Page  

Amp next page is an amp component which can dynamically load more pages when the user reaches at the end of the document. This chapter deals with this concept in detail.

To work with amp-next-page component we need to add following script − 

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

Also amp-next-page is not fully launched, so to get the test page working add the following meta tag −

<meta name = "amp-experiments-opt-in" content = "amp-next-page">

To load the pages dynamically, we need to give the page-urls to the script tag of type=”application/json” as shown below −

<amp-next-page>
   <script type = "application/json">
      {

         "pages": [
            {
            "title": "Page 2",
            "image": "images/christmas1.jpg",
            "ampUrl": "ampnextpage1.html"
            },
            {
            "title": "Page 3",
            "image": "images/christmas1.jpg",
            "ampUrl": "ampnextpage2.html"
            }
         ]
      }
   </script>
</amp-next-page>

In the above tag, we are trying to load 2 pages ampnextpage1.html and ampnextpage2.html.

Now, let us see the final output. All the pages that need to be loaded has to be added to the pages array with title, image and ampUrl.

Example

<!doctype html>
<html amp>
   <head>
      <meta charset = "utf-8">
      <title>Google Amp - Next Page</title>
      <link rel = "canonical" href = "ampnextpage.html">
      <meta name = "amp-experiments-opt-in" content = "amp-next-page">
      <meta name = "viewport" content ="width = device-width,
      minimum-scale = 1,initial-scale = 1">

      <style amp-boilerplate>
         body {
            -webkit-animation:
            -amp-start 8s steps(1,end) 0s 1 normal both;-moz-animation:
            -amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:
            -amp-start 8s steps(1,end) 0s 1 normal both;animation:
            -amp-start 8s steps(1,end) 0s 1 normal both
         }
         @-webkit-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}
      </style>

         <style amp-boilerplate>
            body{
               -webkit-animation:none;
               -moz-animation:none;
               -ms-animation:none;
               animation:none
