代码如下：function addDiv(w,h){
deleteDiv()
//创建一个div
var my = document.createElement("divCell")
//添加到页面
document.body.appendChild(my)
my.style.position="absolute"
//通过样式指定x坐标(随机数0~450)
my.style.top= Math.round(Math.random()*450)
//通过样式指定y坐标(随机数0~700)
my.style.left= Math.round(Math.random()*700)
//通过样式指定宽度
my.style.width=w
//通过样式指定高度
my.style.height=h
//通过样式指定背景颜色,,若是背景图片 例为my.style.backgroundImage="url(img/3.jpg)"
my.style.backgroundColor="#ffffcc"
//添加div的内容
//my.innerHTML=i++
//设置样式透明
my.style.filter = "alpha(opacity=50)"
//设置ID
my.id = "divCell"
}
function deleteDiv()
{
var my = document.getElementById("divCell")
if (my != null)
my.parentNode.removeChild(my)
}
