JS代码:
(function() { var eleBtn = document.getElementById("button"), eleMore = document.getElementById("more"); var height = 0, display = false, timer; var step = function() { height = display? (height + 20): (height - 20); if (height < 0) { height = 0; } else if (height > 191) { height = 191; } eleMore.style.height = height + "px"; if (height > 0 && height < 191) { timer = setTimeout(step, 30); } }; eleBtn.onclick = function() { if (timer) clearTimeout(timer) display = !display; step(); return false; }; })();
