hta：HTML Applications
hta是html的可执行程序，制作很简单，将文件*.htm改为*.hta就可以了。
不过hta有自己独有的标签<hta>，并可设置其属性达到很不错的效果。
hta是制作小程序绝佳选择。
下面是一个例子，几天前在公司无聊时写的。
代码：
<HTML>
<HEAD>
<HTA:APPLICATION
CAPTION="no"
SCROLL="no"
SHOWINTASKBAR="no"
INNERBORDER="no"
CONTEXTMENU="no"
BORDER="none"
SINGLEINSTANCE="yes"
WINDOWSTATE="maximize"
>
<title>0009.cnblogs.com</title>
<SCRIPT>
var timer = 100;
var randDiv = new Array(100);
window.onload = function()
{
for(var i = 0; i < randDiv.length; i++)
{
randDiv[i] = document.createElement("DIV");
randDiv[i].style.cssText = "filter:progid:DXImageTransform.Microsoft.Alpha(opacity=50);";
randDiv[i].style.position = "absolute";
randDiv[i].style.background = GetRandomColor();
document.body.appendChild(randDiv[i]);
}
Fun();
}
function Fun()
{
for(var i = 0; i < randDiv.length; i++)
{
randDiv[i].style.top = Math.floor(Math.random() * window.screen.height);
randDiv[i].style.left = Math.floor(Math.random() * window.screen.width);
randDiv[i].style.width = Math.floor(Math.random() * 100);
randDiv[i].style.height = Math.floor(Math.random() * 100);
randDiv[i].style.background = GetRandomColor();
}
setTimeout("Fun()", timer);
}
function GetRandomColor()
{
var r = Math.floor(Math.random() * 255).toString(16);
var g = Math.floor(Math.random() * 255).toString(16);
var b = Math.floor(Math.random() * 255).toString(16);
r = r.length == 1 ? "0" + r : r;
g = g.length == 1 ? "0" + g : g;
b = b.length == 1 ? "0" + b : b;
return "#" + r + g + b;
}
</SCRIPT>
</HEAD>
<BODY>
