amp-component에서 액션이나 이벤트를 사용하려면 on 속성을 사용할 수 있습니다. 이 글에서는 이에 대해 자세히 설명하겠습니다.
Events
이벤트에 대한 액션 구문은 다음과 같습니다.
on="eventName:elementId[.methodName[(arg1=value, arg2=value)]]"
on 속성에 전달되는 세부 사항은 다음과 같습니다.
- eventName: amp 구성 요소에 사용할 수 있는 이벤트의 이름을 사용합니다. 예를 들어, forforms는 submit-success, submit-error eventNames를 사용할 수 있습니다.
- elementId: 이벤트가 호출되어야하는 요소의 ID를 가져오며 성공 또는 오류에 대해 알고자하는 양식의 ID가 될 수 있습니다.
- methodName: 이벤트 발생시 호출할 메서드의 이름을 사용합니다.
- arg=value: 메서드에 전달된 key=value 형식의 인수를 사용합니다.
on 속성에 여러 이벤트를 전달할 수도 있으며 다음과 같이 수행됩니다.
on="submit-success:lightbox;submit-error:lightbox1"
이벤트가 여러 개인 경우 on 속성으로 전달되고 세미콜론 (;)을 사용하여 구분됩니다.
Actions
액션은 기본적으로 on 속성과 함께 사용되며 구문은 다음과 같습니다.
on="tab:elementid.hide;"
다음과 같이 여러 액션을 전달할 수 있습니다.
on="tab:elementid.open;tab:elementid.hide;”
Elementid는 action이 수행될 요소의 ID입니다.
Amp에는 모든 amp 구성 요소에서 사용할 수 있는 전역적으로 정의된 이벤트 및 액션이 있습니다. 액션은 탭 이벤트와 hide, show 및 togglevisibility이 있습니다.
참고:
모든 html 또는 amp 구성 요소에서 togglevisibility를 숨기거나
표시하거나 사용하려면
on="tap:elementid.[ hide / show / togglevisibility ]"를 사용할 수
있습니다.
이벤트 및 액션에 대한 몇 가지 예제를 살펴보겠습니다.
Input 요소
실전 예제의 도움으로 이것을 더 잘 이해합시다.

결과
위의 예에서는 다음과 같이 input 필드에 이벤트를 사용하고 있습니다.
<input id="txtname" placeholder="Type here" on="input-throttled:AMP.setState({name:event.value})">
input-throlled입니다. 다음과 같이
change를 사용할 수도 있습니다.
<input id="txtname" placeholder="Type here" on="change:AMP.setState({name:event.value})">
사용자가 input 상자 입력하면 출력이 표시됩니다. input 유형에 대한 이벤트를 radio, checkbox 등으로 사용할 수 있으며 select 요소에서도 사용할 수 있습니다.
<input id="txtname" placeholder="Type here" on="input-debounced:AMP.setState({name:event.value})">
input-debounced 이벤트는 change 이벤트와 동일하지만
사용자가 입력한 후 300ms 후에 출력이 표시됩니다.
