Brython documentation

Problem

Store objects locally, using HTML5 Local Storage

Solution

Brython provides a built-in module browser.local_storage that stores string values associated to string keys

Store value in input field

from browser import document as doc
from browser.local_storage import storage
storage['brython_test'] = doc['zone'].value

Show stored value

from browser import alert
from browser.local_storage import storage
alert(storage['brython_test'])

If a Python object can be serialized by the json module, you can store the serialized version, then retrieve the original object :

from browser import alert
from browser.local_storage import storage
import json

a = {'foo':1,1515:'Marignan'}

storage["brython_test"] = json.dumps(a)

b = json.loads(storage['brython_test'])
alert(b['foo'])
alert(b['1515'])

Beware that json converts dictionary keys to their string value, this is why we use b['1515'] instead of b[1515]
