How to check if search input is received in Google AMP ?

Last Updated : 01 Oct, 2020

We can check if a search is received in AMP with the help of amp-autocomplete which can be used to check the specified query parameters with the help of src and query attribute

eg. if a src="https://www.iamageek.org/" and query="q", then a user who types in geek will get the fetch JSON result from https://iamageek.com?q=geek

When the query attribute is paired with the src attribute then user inputs are passed to a statically generated endpoint.

Script Required:

Importing the amp-autocomplete component.

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

Importing the amp-form component.

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

Specifying query parameters:

The input is given trough the input tag and is queried using the template tag when submitted

<form class="sample-form"
  method="post"
  action-xhr="https://amp.dev/documentation/examples/api/echo"
  target="_top"> 
  <amp-autocomplete filter="none"
    min-characters="1"
    src="https://amp.dev/samples_templates/products_autosuggest"
    query="q"> 
    <input type="search"
      name="queryInput"> 
  </amp-autocomplete> 
  <input type="submit"
    value="Search"> 
  <div submit-success> 
    <template type="amp-mustache"> 
      Success! Received <strong>{{queryInput}}</strong>. 
    </template> 
  </div> 
</form>
