javascript - check if the youtube video is paused -

i have video youtube embed in website.

i want know if can show me how check if video paused. here code:

<img id="imagevideo" src="assets/img/landingpage-videothumbnail02.jpg"           data-video="http://www.youtube.com/embed/mm9dztc0ipk?autoplay=1" alt="" width="100%" height="274px" /> 

this script when image clicked, video played:

$('#imagevideo').click(function(){     video = '<iframe src="'+ $(this).attr('data-video') +'"></iframe>';     $(this).replacewith(video); }); 

here have been trying check if video paused:

var paused = $("iframe .html5-main-video").paused;     if(paused)         {             alert ("it paused");         } 

that because when inspect element, video of youtube has class of html5-main-video.

but doesn't alert function.

help, please. thanks
