javascript - Money.js + LocalStorage rates -


i'm using intel xdk make conversion tool, script detects if device has internet connection, if yes use latest rate openexchangerates via json , storage in localstorage:

$.getjson('https://openexchangerates.org/api/latest.json?app_id=xxxxxxxxxxxxxxxxxxxxxxxxxx',function(data) {                     var localdata = json.stringify(data);                     localstorage.setitem('convrates', localdata);                     // check money.js has finished loading:                     if ( typeof fx !== "undefined" && fx.rates ) {                         fx.rates = data.rates;                         fx.base = data.base;                     } else {                         // if not, apply fxsetup global:                         var fxsetup = {                             rates : data.rates,                             base : data.base                         }                     }                 }); 

this ok! when try info localstorage, nothing happens...

var localdata = json.parse(localstorage.getitem('convrates'));             $.getjson(localdata,function(data) {                     // check money.js has finished loading:                     if ( typeof fx !== "undefined" && fx.rates ) {                         fx.rates = data.rates;                         fx.base = data.base;                     } else {                         // if not, apply fxsetup global:                         var fxsetup = {                             rates : data.rates,                             base : data.base                         }                     }              }); 

this json data exemple:

i don't know how make it.

you can treat localstorage kind of normal js object, first off don't need stringify , parse js object. instead of writing

var localdata = json.stringify(data); localstorage.setitem('convrates', localdata); 

you can do

localstorage['convrates'] = data; 

or even

localstorage.convrates = data; 

to retrieve data, may still want use getitem(), return null rather throw error if convrates doesn't exist, retrieve data again do

data = localstorage.getitem('convrates'); 

which leave data either null or convrates object stored there.

calling $.getjson on localdata doesn't make sense, that's js object, not url.
