* @class Ext.state.CookieProvider

12 |
* @extends Ext.state.Provider
|
|
|
13 |
* The default Provider implementation which saves state via cookies.
|
|
|
14 |
* <br />Usage:
|
|
|
15 |
<pre><code>
|
|
|
16 |
var cp = new Ext.state.CookieProvider({
|
|
|
17 |
path: "/cgi-bin/",
|
|
|
18 |
expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
|
|
|
19 |
domain: "extjs.com"
|
|
|
20 |
});
|
|
|
21 |
Ext.state.Manager.setProvider(cp);
|
|
|
22 |
</code></pre>
|
|
|
23 |
* @cfg {String} path The path for which the cookie is active (defaults to root '/' which makes it active for all pages in the site)
|
|
|
24 |
* @cfg {Date} expires The cookie expiration date (defaults to 7 days from now)
|
|
|
25 |
* @cfg {String} domain The domain to save the cookie for. Note that you cannot specify a different domain than
|
|
|
26 |
* your page is on, but you can specify a sub-domain, or simply the domain itself like 'extjs.com' to include
|
|
|
27 |
* all sub-domains if you need to access cookies across different sub-domains (defaults to null which uses the same
|
|
|
28 |
* domain the page is running on including the 'www' like 'www.extjs.com')
|
|
|
29 |
* @cfg {Boolean} secure True if the site is using SSL (defaults to false)
|
|
|
30 |
* @constructor
|
|
|
31 |
* Create a new CookieProvider
|
|
|
32 |
* @param {Object} config The configuration object
