2、测试：
<html>
<script language="JavaScript" type="text/javascript" src="2ini.js"></script>
<script>
var Ini = new IniCtrl();
//Ini.Create("c:\\jstest\\setting.ini");
Ini.Open("c:\\jstest\\setting.ini");
Ini.AddSetting("Admin");
//配置增加属性
Ini.select("Admin");
Ini.setAttribute("user","aaaaaa");
Ini.setAttribute("pass","123123");
//保存配置
Ini.save();
Ini.Close();
</script>
</html>
