</div>
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';
}
