I have a simple JSFiddle here: http://jsfiddle.net/cvCWc/2/ The basic code looks like: window.player = videojs("movie_container", { techOrder: ["html5", "slash"] }, function() { videojs_player = this; videojs_player.src({ src: "http://video-js.zencoder.com/oceans-clip.mp4", type: 'video/mp4'}) videojs_player.on("click", function(event){ event.preventDefault(); alert('click'); }); videojs_player.play(); }); I am trying to capture all click events on the video for future processing, but I don't want the video to pause when clicked. Any ideas? I found the answer for HTML5... but I don't get click
