extra text in Vimeo Embedded videos

Question

I add a frame ID using an each function’s index, and then appending the src with the string you need:

jQuery('#video-gallery-list li.video-player').each(function(i) {
    // set up a variable for the src that includes the new unique ID you're about to use
    var this_src = jQuery(this).find('iframe').attr('src') + '?api=1&amp;player_id=player_'+i;
    jQuery(this).find('iframe').attr('ID', 'player_'+i).attr('src',this_src);
});
