store.js
2 +
========
3 + 4 +
store.js exposes a simple API for cross browser local store
5 + 6 +
// Store 'marcus' at 'username'
7 +
store.set('username', 'marcus')
8 + 9 +
// Get 'username'
10 +
store.get('username')
11 + 12 +
// Delete 'username'
13 +
store.delete('username')
14 + 15 +
// Clear all keys
16 +
store.clear()
17 + 18 +
// Use JSON to stash an object (see http://www.json.org/json2.js)
19 +
store.set('user', JSON.stringify({ name: 'marcus', likes: 'javascript' }))
20 + 21 +
// Use JSON to retrieve an object (see http://www.json.org/json2.js)
22 +
var user = JSON.parse(store.get('user'))
23 +
alert(user.name + ' likes ' + user.likes)
24 + 25 +
TODO

27 +
I wrote store.js in the past hour looking at https://developer.mozilla.org/en/dom/store and http://msdn.microsoft.com/en-us/library/ms531424.aspx. I haven't tested it yet though.
28 + 29 +
- I believe underlying APIs can throw under certain conditions. Where do we need try/catch?
30 +
- Write tests
31 +
- Test in IE6
32 +
- Test in IE7
33 +
- Test in IE8
34 +
- Test in Firefox 2.0
35 +
- Test in Firefox 3.0
36 +
- Test in Firefox 3.5
37 +
- Test in Firefox 3.6
38 +
- Test in Safari 2
39 +
- Test in Safari 3
40 +
- Test in Safari 4
41 +
- Test in Safari 5
42 +
- Test in Chrome 4
43 +
- Test in Chrome 5
