          '<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">'+

                '</div>'+
                '<div class="modal-body"></div>'+

          '</div>'

            
            
            
//          var url_mobi=data.url_mobi;
//          var url_pc=data.url_pc;
//          if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|iOS|iPad|Backerry|WebOS|Symbian|Windows Phone|Phone)/i))) {
//              $('.modal-body').prepend(url_mobi);
//              }else{
//              $('.modal-body').prepend(url_pc);
//              }
//              
//              
              })
          
          $('.medialist').after(mediahtml);  
          
          
        })
          
          
        })
        


        $('#myModal').on('shown.bs.modal', function (e) {
          // 关键代码，如没将modal设置为 block，则$modala_dialog.height() 为零 
          $(this).css('display', 'block');
          var modalHeight = $(window).height() / 2 - $('#myModal .modal-dialog').height() / 2;
          $(this).find('.modal-dialog').css({
            'margin-top': modalHeight
          });
        });


        //点击预览图时判断
//        $('.modal').on('click', function () {
//          if ($('#myModal').css("display") == "none") {
//            $('.modal-body').children('iframe').attr('src', '');
//          } else {
//            $('.modal-body').children('iframe').attr('src',
//              'https://v.qq.com/iframe/player.html?vid=v0508nqkm75&tiny=0&auto=0');
