Advanced Server Request

Introduction

This sample demonstrates how to display data from a server in an email and refresh it subsequently while taking the user's input into account.

Because AMP for Email doesn't allow binding to [src] in amp-list, it uses a combination of amp-list and amp-form that share the same amp-mustache template. When the form is submitted for the first time, the amp-list is hidden and the form's response takes its place.

Implementation

Define a template and give it an id to allow it to be used from both amp-list and amp-form.

<template id="animal-template"
  type="amp-mustache">
  <p>This displays data sent from a server.</p>
  {{#animal}}
    <p>You have selected {{animal}}.</p>
  {{/animal}}
</template>

When the user changes the selection, the change event triggers the form submission and hides the amp-list: on="change:animal-form.submit,animal-list.hide".

The amp-form renders the server response using the same template as amp-list, making the switch from amp-list to amp-form appear seamless.

Use a placeholder to make the loading state look the same as the submitting state for the form.

Select an animal to update the server response.
