To make a json string, I use the JSON object which I paste in from any place where there's a JSON object. I just grab whichever one works, from here: GitHub - douglascrockford/JSON-js: JSON in JavaScript.

Using it in above code it would look like this:

var jsonString = JSON.stringify({myText : txtbox.text});

To write a file you do the following code:

var f = File(<write your file's directory here. Ex: "~/Desktop/myFile.txt">);

f.open('w'); // w for 'write'

f.write(jsonString);

f.close();

is there a particular reason you need JSON? i find js objects easier to read than a json file

here is what i do:

make an object with the preferences:

     var prefs = {}

          prefs.txtbox = "something"

          prefs.btnsave = "something"

          prefs.btnretrive = "something"

save object to file:

var file = File(directory);

     file.open('w')

     file.write(prefs.toSource())

     file.close()

open saved object:

    file.open("r")

    prefs = eval(file.read())

    file.close();

btw, you can use any extension you want for the file, it will read just the same. i made a custom extension for all my script preferences.

Thanks Te_co,

could you tell me how to validate this xml. since when i have txtbox value already exists.it must alert that it was already exists.else save data.

suppose,

prefs.txtbox = "Illu"

//button clicked it saved

*************************

then again

prefs.txtbox = "Illu"

//button clicked alert "already exists"

Please help me.

Thank you.

i don't know. i don't fully understand what you are trying to accomplish.

does it matter if prefs.txtbox exists? why not just overwrite it silently?

It works, but how do i read this data? simply using prefs.textbox does not work in this case
