Google AMP amp-autocomplete用法及代码示例


amp-autocomplete根据用户键入时给出的输入建议完整结果。这是一个非常常见且有用的函数，因为它使用户可以更快地完成任务。当用户不知道输入的全部范围时，这非常有用。

必需的脚本：导入amp-autocomplete组件-

HTML

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

导入amp-form组件-



HTML

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

用法：

  • amp-autocomplete必须嵌套在表单中。
  • 表单应包含带有输入标签或textarea标签的输入字段。
  • 数据源必须是包含数组属性项的JSON对象。
  • 可以使用子脚本type =“ application /json”标签指定数据源，也可以通过src标签指定数据源。

使用子脚本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标记-

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>
