}
        for(let i=0;i<l.length;i++){
            l[i].onclick = function(){
                this.style.background='red';
                    document.getElementById('count_').innerHTML = 'Выбрано мест : '+Count_Mest ();
            }
        }
</script> 
</body>
</html>

вот что я пробовал

var l = document.getElementsByClassName('mesta'); 
    
      let c = [];
      for(let i=1;i<+8;i++){
           c.push(i)
          
      }
      console.log(c);
      l.write('<div>' + c + '<div />');
