onload = function(){ //加載完畢給div添加點擊事件，可以不這么做，像下面的reset / apply一樣建立一個函數并在該div上寫上Onclick點擊事件調用函數即可 var btn = document.getElementById('button').getElementsByTagName('div'); btn[0].onclick = function(){ document.getElementById('set').style.display = 'block'; }}var box = document.getElementById('box'); //建立全局變量獲取DIV對象function wd(x){ //改變寬度 box.style.width = x + 'px';}function hd(x){ //改變高度 box.style.height = x + 'px';}function cl(x){ //改變顏色 box.style.background = x;}function apply(){ document.getElementById('set').style.display = 'none';}function reset(){ //恢復DIV原來的布局 box.style.width = 100 + 'px'; box.style.height = 100 + 'px'; box.style.background = 'white';}以上就是本文的全部內容，希望本文的內容對大家的學習或者工作能帶來一定的幫助，同時也希望多多支持武林網！
