Since W8.1 (actually IE 11 with W7 will work also) microsoft has a Javascript runtime that can be called from scripting languages As shown in this example from C++: https://iobservable.net/blog/2013/11/12/introduction-to-jsrt/ By loading either JSCRIPT9.DLL or CHAKRA.DLL you can embed ECMA JavaScript in your application And implemented here in AutoHotKey https://autohotkey.com/boards/viewtopic.php?f=6&t=5739 Triggered by other threads: https://www.autoitscript.com/forum/topic/185883-accessing-autoit-variables/ https://iobservable.net/blog/2013/11/12/introduction-to-jsrt/ https://www.autoitscript.com/forum/topic/184824-chakracore-udf-executing-javascript-in-autoit/ http://eclipsesource.com/blogs/2016/04/06/getting-started-with-microsoft-chakracore/ This code is almost working but unfortunately not with the expected output.
