var isIphone = navigator.userAgent.indexOf(‘iPhone‘) >= 0;
// Other way to detect iOS
// var isIOS = /iPad|iPhone|iPod/.test(navigator.platform);

if (isIphone) {

    new CanvasVideoPlayer({
        // Options
    });
}

}

$(function(){
        var isIphone = navigator.userAgent.indexOf(‘iPhone‘) >= 0;
        if (isIphone) {
            $(".play_video").click(function(){
                window.location="视频的绝对地址url"
            });
        }
        else {
            $(".play_video").click(function(){
                
                var videoHtml = "<video id=\"video_span\" class=\"url_video\" src=\"视频的绝对地址url\" x-webkit-airplay=\"true\" webkit-playsinline=\"true\" poster=\"视频封面图片的绝对地址\" preload=\"null\" loop=\"loop\" autoplay  controls=\"controls\"></video>"
                $("#video_div").html(videoHtml)
