之前写过一篇文章：获取AppStore上架后的应用版本号，那一篇文章使用node.js实现，存在的问题就是如果在没有安装node.js运行环境下是无法运行的，而且该程序依赖request模块，为了方便其它人也能使用，想到把它做成一个本地应用程序。然后想了一下，觉得最简单的就是使用hta文件(它的Ajax请求可跨域^_^)。
因为我们手游产品已经有三款了，所以“应用地址”那一栏，我使用了下拉框，其它组的成员只需要点击选中需要检测的应用，然后点击“检测版本”按钮，程序将开始运行。当匹配到版本为最新的版本时，登录OA系统，向需要获取版本更新信息的人员发送OA提醒。
原理比较简单，代码也并不复杂。将源码本地另存为.hta后缀的文件，然后双击它就可以运行了。
