With AJAXs help it's posible to load data from file, but is it possible to save a value of string variable to file? I want to hold data in file with .txt extension and load it when I will need it.

Yes, just send this string data to your backend file and write this string to an existing file or new file in the backend file. Maybe I am misunderstanding your question. – The One and Only ChemistryBlob Aug 30 '16 at 13:23

You will need a server side. Assuming you do, send the data back and forth via GET/POST, and edit/save it from the server side. Unless you want the user to pick the file themselves, you can use the FileReader js object with . Otherwise, for security reasons, you cannot. That would give your system access to any user's home directories on their machine.
