How to update text in .txt file which is opened from $.get

Question

I can read/open it but don't know how to update the specific value in it.

My data.txt is like

[
  {"slot": "1", "name": "Bob"},
  {"slot": "2", "name": "John"}
]

then i want to update it like query the database "UPDATE data.txt SET name='James' WHERE slot=2"

After update, I want data.txt to be like

[
   {"slot": "1", "name": "Bob"},
   {"slot": "2", "name": "James"}
]

How can I do this with javascript, Ajax, Jquery

You can't do this with a flat file, you need some form of REST-type interface that allows you to query and update the file, I suggest you switch to a database; seeing as you already seem to know how to do it if it was a database.
