How to Control an Existing iframe YouTube Player with JavaScript API

The YouTube iframe API is commonly used to add and control YouTube videos on web pages. However, what if you want to control an iframe-based YouTube player that is already present in the HTML?

Traditionally, controlling such players was straightforward with the old embed method. However, this approach doesn't work with the newer iframe players. To address this, we're introducing a solution that allows you to assign an iframe player object and use the API functions on it.

Solution: callPlayer Function

The callPlayer function is a powerful tool that enables you to execute function calls on any framed YouTube video. This means you can access a comprehensive list of possible function calls, including playing, pausing, and seeking.

Implementation

function callPlayer(frame_id, func, args) {
    // ... Function implementation
}

To use the callPlayer function, simply provide the following parameters:

• frame_id: The ID of the element containing (or itself containing) the YouTube player iframe.
• func: The desired function to call, e.g., "playVideo".
• args: (Optional) An array of arguments to pass to the function.

Example Usage

Here are some examples of how to use the callPlayer function:

• Play a video:

callPlayer("my-video-iframe", "playVideo");

• Pause a video:

callPlayer("my-video-iframe", "pauseVideo");

• Seek to a specific time:

callPlayer("my-video-iframe", "seekTo", [100, true]); // Seek to 100 seconds, allow seek ahead

• Receive player status updates:

callPlayer("my-video-iframe", "listening");

Additional Notes

• The callPlayer function will queue functions if the player is not yet ready.
• It will log an error message to the console if the iframe player cannot be found.
• To enable autoplay, remember to include "?enablejsapi=1" at the end of your iframe URL.
• The function is compatible with browsers that support JSON and postMessage (i.e., IE 8+, Firefox 3.6+, etc.).

Conclusion

The callPlayer function is an invaluable tool that empowers you to seamlessly control existing iframe-based YouTube players with the JavaScript API. This powerful technique opens up a wide range of possibilities for web developers, enabling them to create interactive and immersive video experiences on their websites.
