一个有意思的 hta 程序 （html application）
哈哈，刚才同事给我讲了一个hta 程序，他自己说最近在学html5 开发坦克大战，不错，这种好奇心， 好学的精神值得我这个程序员学习，感觉他的视野面比我这个程序员还广，有点小惭愧。
什么是hta 呢？（其实说白了，就是html+javascript +css）只不过，宿主环境不是浏览器，而是桌面程序！！
百度百科：
HTA是HTML Application的缩写（HTML应用程序），是软件开发的新概念，直接将HTML保存成HTA的格式，就是一个独立的应用软件，与VB、C++等程序语言所设计的软件界面没什么差别
HTA与普通的网页结构差不多，所以设计出来很容易，当然HTA还有许多自己独特的属性：
程序的权限
HTA虽然用HTML、JS和CSS编写，却比普通网页权限大得多。它具有桌面程序的所有权限（读写文件、操作注册表等）。HTA本来就是被设计为桌面程序的。
语法的要求
HTA对语法的要求比HTML还要松，甚至连<html>、<body>等标记都可以省略：
下面是一个hta写的迷宫游戏：
