How to Control Existing YouTube iframes with the YouTube iframe API?

YouTube iframe API: Controlling Pre-existing iframe Players

The YouTube iframe API provides comprehensive functionality for controlling embedded videos. While the documentation typically focuses on adding new players to a page, it is also possible to manipulate existing iframe-based YouTube players.

Using the callPlayer Function

To control pre-existing iframe players, utilize the callPlayer function, authored by Rob W. This function allows you to invoke any supported YouTube player function.

callPlayer(frame_id, func, args);
Copy after login

Parameters:

  • frame_id: The ID of the iframe containing the YouTube player.
  • func: The player function you wish to execute, such as "playVideo" or "pauseVideo".
  • args: An optional array of arguments to pass to the player function.

Example Usage:

callPlayer("whateverID", "playVideo");
Copy after login

This code will play the video in the iframe with the ID "whateverID".

Ensuring Player Readiness

Before using callPlayer, ensure that the YouTube player is ready. If it is not yet ready, the function will queue the request until the player becomes available.

Listening for Player Events

The callPlayer function also supports listening for player events. To do so, pass "listening" as the func parameter.

callPlayer("whateverID", "listening");
Copy after login

This will establish a message event listener that will receive status updates from the YouTube player.

Other Considerations:

  • Ensure that the iframe URL includes "?enablejsapi=1".
  • The API may not function properly when hosted locally (file://).
  • Browser support includes IE 8 , Firefox 3.6 , Opera 10.50 , Safari 4 , and Chrome 3 .
