問題描述
YouTube（注入）視頻結束回調 (YouTube (injected) video ends callback)
I inject YouTube iframe to a div in document ready and bind it to click:
jQuery(document).ready(function($) {
jQuery('.video-thumb').click(function(){
...
$('#player').html('<iframe width="761" height="421" src="http://www.youtube.com/embed/' + $(this).attr('videoid') + '?rel=0&wmode=transparent" frameborder="0" allowfullscreen></iframe>');
...
}
}
And I want to do a callback when video ends. I have read about onYouTubePlayerAPIReady, but it has to be put outside document ready.
I have tried to load video player by this construction outside document ready:
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '421',
width: '761',
videoId: '',
playerVars: { autoplay: 1, autohide: 1, showinfo: 0 },
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
but I got some issues:
- showinfo:0 didn't work, still got other video thumbnails in the end
- I don't know how to change video id (and reinit the video?)
- more script errors than first method (injecting iframe)
I prefer using first method, but how to create video ends callback? Thanks.
參考解法
方法 1:
A working example of the below code is also on jsfiddle.net.
Some notes:
- Uses the iframe_api, not the javascript_api
- The YT.Player constructor is minimal because you are building the iframe yourself.
- The "playerVars" are included as iframe URL parameters.
- The parameter "enablejsapi=1" is set.

The JavaScript
function log(msg) {
jQuery('#log').prepend(msg + '<br/>');
}
function onPlayerStateChange(event) {
switch(event.data) {
case YT.PlayerState.ENDED:
log('Video has ended.');
break;
case YT.PlayerState.PLAYING:
log('Video is playing.');
break;
case YT.PlayerState.PAUSED:
log('Video is paused.');
break;
case YT.PlayerState.BUFFERING:
log('Video is buffering.');
break;
case YT.PlayerState.CUED:
log('Video is cued.');
break;
default:
log('Unrecognized state.');
break;
}
}
jQuery(document).ready(function($) {
$('.video-thumb').click(function() {
var vidId = $(this).attr('id');
$('#container').html('<iframe id="player_'+vidId+
'" width="420" height="315" src="http://www.youtube.com/embed/'+
vidId+'?enablejsapi=1&autoplay=1&autohide=1&showinfo=0" '+
'frameborder="0" allowfullscreen></iframe>');
new YT.Player('player_'+vidId, {
events: {
'onStateChange': onPlayerStateChange
}
});
});
});
