/** * @class Ext.state.CookieProvider * @extends Ext.state.Provider * A Provider implementation which saves and retrieves state via cookies. * The CookieProvider supports the usual cookie options, such as: * <ul> * <li>{@link #path}</li> * <li>{@link #expires}</li> * <li>{@link #domain}</li> * <li>{@link #secure}</li> * </ul> <pre><code> var cp = new Ext.state.CookieProvider({ path: "/cgi-bin/", expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days domain: "sencha.com" }); Ext.state.Manager.setProvider(cp); </code></pre> * @cfg {String} path The path for which the cookie is active (defaults to root '/' which makes it active for all pages in the site) * @cfg {Date} expires The cookie expiration date (defaults to 7 days from now) * @cfg {String} domain The domain to save the cookie for. Note that you cannot specify a different domain than * your page is on, but you can specify a sub-domain, or simply the domain itself like 'sencha.com' to include * all sub-domains if you need to access cookies across different sub-domains (defaults to null which uses the same * domain the page is running on including the 'www' like 'www.sencha.com') * @cfg {Boolean} secure True if the site is using SSL (defaults to false) */ Ext.define('Ext.state.CookieProvider', { extend: 'Ext.state.Provider', /** * Creates a new CookieProvider. * @param {Object} config (optional) Config object. */ constructor : function(config){ var me = this; me.path = "/"; me.expires = new Date(new Date().getTime()+(1000*60*60*24*7)); //7 days me.domain = null; me.secure = false; me.callParent(arguments); me.state = me.readCookies(); }, // private set : function(name, value){ var me = this; if(typeof value == "undefined" || value === null){ me.clear(name); return; } me.setCookie(name, value); me.callParent(arguments); }, // private clear : function(name){ this.clearCookie(name); this.callParent(arguments); }, // private readCookies : function(){ var cookies = {}, c = document.cookie + ";", re = /\s?(.*?)=(.*?);/g, prefix = this.prefix, len = prefix.length, matches, name, value; while((matches = re.exec(c)) != null){ name = matches[1]; value = matches[2]; if (name && name.substring(0, len) == prefix){ cookies[name.substr(len)] = this.decodeValue(value); } } return cookies; }, // private setCookie : function(name, value){ var me = this; document.cookie = me.prefix + name + "=" + me.encodeValue(value) + ((me.expires == null) ?
