• Usage

dojox/mvc/StoreRefController is an inheritance of dojox/mvc/ModelRefController, which keeps a reference to Dojo Object Store (in store property). It has several methods to work with the store:

• queryStore(): Runs query() against the store, and creates a data model from retrieved data
• getStore(): Runs get() against the store, and creates a data model from retrieved data
• putStore(): Runs put() against the store
• addStore(): Runs add() against the store
• removeStore(): Runs remove() against the store

dojo/Stateful get()/set()/watch() interfaces in dojox/mvc/StoreRefController will work with the data model from queryStore() or getStore().

Usage

In the example below, the text box refers to value property in the controller (with ctrl ID). The controller provides the value property, from the data coming from data store (store property in the controller). After two seconds, the text box changes from Foo to Bar as the controller gets new data from data store.

require([
    "dojo/parser", "dojo/when", "dijit/registry", "dojo/domReady!"
], function(parser, when, registry){
    when(parser.parse(), function(){
        registry.byId("ctrl").getStore("Foo");
        setTimeout(function(){ registry.byId("ctrl").getStore("Bar"); }, 2000);
    });
});

require([ "dojo/parser", "dojo/when", "dijit/registry", "dojo/domReady!" ], function(parser, when, registry){ when(parser.parse(), function(){ registry.byId("ctrl").getStore("Foo"); setTimeout(function(){ registry.byId("ctrl").getStore("Bar"); }, 2000); }); });
