Google AMP amp-autocomplete用法及代碼示例


amp-autocomplete根據用戶鍵入時給出的輸入建議完整結果。這是一個非常常見且有用的函數，因為它使用戶可以更快地完成任務。當用戶不知道輸入的全部範圍時，這非常有用。

必需的腳本：導入amp-autocomplete組件-

HTML

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

導入amp-form組件-



HTML

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

用法：

  • amp-autocomplete必須嵌套在表單中。
  • 表單應包含帶有輸入標簽或textarea標簽的輸入字段。
  • 數據源必須是包含數組屬性項的JSON對象。
  • 可以使用子腳本type =“ application /json”標簽指定數據源，也可以通過src標簽指定數據源。

使用子腳本type =” application /json”-

HTML

<form class="sample-form" method="post" 
    action-xhr= 
"https://amp.dev/documentation/examples/api/echo"
    target="_top"> 
      
    <amp-autocomplete filter="substring"> 
        <input> 
        <script type="application/json"> 
            { 
                "items":["geeksforgeeks", "gfg",  
                "iamageek" ,"how to become a geek?"] 
            } 
        </script> 
    </amp-autocomplete> 
</form>

使用src標記-

HTML

<form class="sample-form" method="post" 
    action-xhr= 
"https://amp.dev/documentation/examples/api/echo"
    target="_top"> 
      
    <!--the following src link contains  
        names of cities-->
    <amp-autocomplete filter="substring" 
src="/static/samples/json/amp-autocomplete-cities.json"> 
        <input> 
    </amp-autocomplete> 
</form>
