var $ = document.querySelector.bind(document);

// Start calendar var c = new Cal("divCal");
c.showcurr();

// Bind next and previous button clicks getId('btnNext').onclick = function() { c.moisProchain(); var td = getClass('jour_normal'); var session; var bloc = document.createElement('div'); bloc.className = 'pref';

            for(var i=0;i<td.length;i++){
                console.log(td[i]);
                td[i].onclick.appendChild(bloc);
                //td[i].addEventListener('click',function(){

                //})





            }                      
    };
