HTML:

<!DOCTYPE HTML><html> <head> <meta charset="utf-8" /> <title></title> <link rel="stylesheet" href="css/style.css" rel="external nofollow" /> </head> <body> <div id="button"><h1>请为下面的DIV设置样式：</h1><div>点击设置</div></div> <div id="set"> <div class="set1"><span>请选择背景色：</span><span onclick="cl('red')">红</span><span onclick="cl('yellow')">黄</span><span onclick="cl('blue')">蓝</span></div> <div class="set2"><span>请选择宽(px)：</span><span onclick="wd(200)">200</span><span onclick="wd(300)">300</span><span onclick="wd(400)">400</span></div> <div class="set2"><span>请选择高(px)：</span><span onclick="hd(200)">200</span><span onclick="hd(300)">300</span><span onclick="hd(400)">400</span></div> <span class="btn" onclick="reset()">恢复</span> <span class="btn" onclick="apply()">确定</span> </div> <div id="box"></div> <script type="text/javascript" src="js/js.js"></script> </body></html>

CSS:

#box{width:100px; height: 100px; border:4px black solid;margin-top:100px;}#button div{background: red; width:100px; height:40px; float:left; color:white; text-align: center; line-height: 40px; cursor: pointer;}#set{width:20%; height:28%; border:15px rgb(156,148,156) solid; background:white; position: absolute; top:300px; left:300px; box-shadow: 0 0 8px gray; display:none;}#set div{height: 40px; margin: 20px auto;}#set div span{width:45px; height:40px; display:block; float:left; margin-left:10px; color:white; line-height:40px; text-align:center; cursor:pointer;}#set div span:hover{border:1px black solid}#set div span:nth-of-type(1){width:auto; color:black; font:18px/40px "微软雅黑"; margin-left:12%; border:none; cursor:auto;} #set .set1 span:nth-of-type(2){background:rgb(230,46,0); margin-left:5px;}#set .set1 span:nth-of-type(2):hover{background:red}#set .set1 span:nth-of-type(3){background:rgb(239,189,0)}#set .set1 span:nth-of-type(3):hover{background:yellow}#set .set1 span:nth-of-type(4){background:rgb(90,148,239)}#set .set1 span:nth-of-type(4):hover{background:blue}#set .set2 span{border:1px rgb(198,198,198) solid; color:rgb(136,140,143)}#set .set2 span:nth-of-type(1):hover{background:white;}#set .set2 span:nth-of-type(2){background:rgb(239,239,239); margin-left:5px;}#set .set2 span:nth-of-type(3){background:rgb(239,239,239)}#set .set2 span:nth-of-type(4){background:rgb(239,239,239)}#set .set2 span:hover{background:rgb(239,148,0)}#set .btn{width:60px; height:30px; background:#002952; color:white; display:block; float:left; margin-left:10px; margin-top:10px; text-align:center; line-height:30px; cursor:pointer;}#set span:nth-of-type(1){margin-left:32%;}

JS:

onload = function(){ //加载完毕给div添加点击事件，可以不这么做，像下面的reset / apply一样建立一个函数并在该div上写上Onclick点击事件调用函数即可 var btn = document.getElementById('button').getElementsByTagName('div'); btn[0].onclick = function(){ document.getElementById('set').style.display = 'block'; }}var box = document.getElementById('box'); //建立全局变量获取DIV对象function wd(x){ //改变宽度 box.style.width = x + 'px';}function hd(x){ //改变高度 box.style.height = x + 'px';}function cl(x){ //改变颜色 box.style.background = x;}function apply(){ document.getElementById('set').style.display = 'none';}function reset(){ //恢复DIV原来的布局 box.style.width = 100 + 'px'; box.style.height = 100 + 'px'; box.style.background = 'white';}
