Limited availability

DocumentPictureInPictureEvent()
构造函数创建一个新的 DocumentPictureInPictureEvent
对象实例。
语法
js
new DocumentPictureInPictureEvent(type, init)
参数
示例
开发者通常不会手动使用此构造函数。当由于触发 enter
事件而调用处理器时,会自动构造一个新的 DocumentPictureInPictureEvent
对象。
js
documentPictureInPicture.addEventListener("enter", (event) => {
const pipWindow = event.window;
console.log("视频播放器已进入画中画窗口");
const pipMuteButton = pipWindow.document.createElement("button");
pipMuteButton.textContent = "静音";
pipMuteButton.addEventListener("click", () => {
const pipVideo = pipWindow.document.querySelector("#video");
if (!pipVideo.muted) {
pipVideo.muted = true;
pipMuteButton.textContent = "取消静音";
} else {
pipVideo.muted = false;
pipMuteButton.textContent = "静音";
}
});
pipWindow.document.body.append(pipMuteButton);
});
