Iframe 控制 ​

说明 ​

通过该插件，你可以轻松在 index.html 里控制跨域 iframe.html 页面里的播放器，如在 index.html 里通过代码控制 iframe.html 播放器的功能，或者获取 iframe.html 播放器的值

            const iframe = new ArtplayerPluginIframe({
                // Iframe element
                iframe: document.querySelector('#iframe'),
                // Iframe url
                url: 'path/to/iframe.html',
            });

            // Send message to iframe
            iframe.commit(() => {

            ArtplayerPluginIframe.inject();
        </script>
    </body>
</html>

index.html 接口 ​

commit ​

从 index.html 将消息推送到 iframe.html，该函数将在 iframe.html 内部运行，同时它也能用于异步获取 iframe.html 里的值

js
iframe.commit(() => {
    var art = new Artplayer({
        container: '.artplayer-app',
        url: 'path/to/video.mp4',
    });
});

iframe.commit(() => {
    art.seek = 5;
});

// Get the value from the iframe.html
(async function () {
    // Use the return keyword
    var currentTime = await iframe.commit(() => {
        return art.currentTime;
    });

    // or use the resolve method
    var currentTime2 = await iframe.commit((resolve) => {
        setTimeout(() => {
            resolve(art.currentTime);
        }, 1000);
    });
})();

message ​

在 index.html 接收来自 iframe.html 的消息

js
iframe.message((event) => {
    console.info(event);
});

destroy ​

销毁后 index.html 无法与 iframe.html 通信

js
iframe.destroy();

iframe.html 接口 ​

提示

iframe.html 接口 只能运行在 iframe.html 里

inject ​

注入脚本，接收来自 index.html 的消息

js
ArtplayerPluginIframe.inject();

postMessage ​

将消息推送到 index.html

js
iframe.message((event) => {
    console.info(event);
});

iframe.commit(() => {
    ArtplayerPluginIframe.postMessage({
        type: 'currentTime',
        data: art.currentTime,
    });
});

例子 ​

最常遇到的问题是，播放器在 iframe.html 里进行网页全屏，但在 index.html 是不生效的，这时候只要监听 iframe.html 里的 fullscreenWeb 事件并通知到 index.html 即可

    <head>
        <title>ArtPlayer</title>
        <meta charset="UTF-8" />

        <iframe id="iframe"></iframe>
        <script src="path/to/artplayer-plugin-iframe.js"></script>
        <style>
            .fullscreenWeb {
                position: fixed;

                width: 100%;
                height: 100%;
                left: 0;
                top: 0;
                right: 0;
                bottom: 0;
            }
        </style>
        <script>
            const $iframe = document.querySelector('#iframe');
            const iframe = new ArtplayerPluginIframe({
                iframe: $iframe,
                url: 'path/to/iframe.html',
            });

            iframe.message(({ type, data }) => {
                switch (type) {
                    case 'fullscreenWeb':
                        if (data) {
                            $iframe.classList.add('fullscreenWeb');
                        } else {
                            $iframe.classList.remove('fullscreenWeb');
                        }
                        break;
                    default:
                        break;
                }
            });

            iframe.commit(() => {
                var art = new Artplayer({
                    container: '.artplayer-app',
                    url: 'path/to/video.mp4',
                });

                art.on('fullscreenWeb', (state) => {
                    ArtplayerPluginIframe.postMessage({
                        type: 'fullscreenWeb',
