how to work with json feed stored in localStorage in phonegap app?

Question

Here\'s what I am doing,

Get request to my web server, response is in json. Using jquery templates to render that callback data in my app. Pretty straightforward, works

Answer 1

You need to use JSON like so:

localStorage.setItem('foo', JSON.stringify(data));

And then parse it:

JSON.parse(localStorage.getItem('foo'))

Answer 2

App.local = (function () {
  var self = {};

  self.get = function (key) {
    var b = localStorage.getItem(key);
    return b ? JSON.parse(b) : null;
  }

  self.set = function (key, value) {
    var b = JSON.stringify(value);
    localStorage.setItem(key, b);
  }

  return self;
})();

Now you have a nice interface to local storage,

var local = App.local;
local.set('foo', 'bar');
var bar = local.get('foo');
console.log(bar);
