Question

I am trying to make an application in phonegap. I have made a custom.js javascript file which have some functions as

Answer 1

in modern browsers you can use localStorage for that

var get = function (key) {
  return window.localStorage ? window.localStorage[key] : null;
}

var put = function (key, value) {
  if (window.localStorage) {
    window.localStorage[key] = value;
  }
}

use get and put to store value to the local storage of most modern browsers..
