Animation.finish() - Web API 接口参考 编辑

这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

The finish() method of the Web Animations API's Animation Interface sets the current playback time to the end of the animation corresponding to the current playback direction. That is, if the animation is playing forward, it sets the playback time to the length of the animation sequence, and if the animation is playing in reverse (having had its reverse() method called), it sets the playback time to 0.

语法

Animation.finish(); 

参数

None.

返回值

None.

异常

InvalidState

The player's playback rate is 0 or the animation's playback rate is greater than 0 and the end time of the animation is infinity.

例子

The following example shows how to use the finish() method and catch an InvalidState error.

interfaceElement.addEventListener("mousedown", function() {
  try {
    player.finish();
  } catch(e if e instanceof InvalidState) {
    console.log("finish() called on paused or finished animation.");
  } catch(e);
    logMyErrors(e); //pass exception object to error handler
  }
});

The following example finishes all the animations on a single element, regardless of their direction of playback.

elem.getAnimations().forEach(
  function(animation){
    return animation.finish();
  }
);
