JavaScript定时器检查sessionStorage隐藏元素

var count = 0; var interval = setInterval(function() { if (count === 60) { clearInterval(interval); return; } count++; var wx = sessionStorage.getItem('wx'); if (wx === '1') { var wxElements = document.getElementsByClassName('wx'); for (var i = 0; i < wxElements.length; i++) { wxElements[i].style.display = 'none'; } clearInterval(interval); } }, 500);
