Registering a JSONm store in sencha touch

Question

I am new in sencha touch application development .I am trying to load some data from remote we server to a list . I created a Store like the following

Ext.regStore('customers',{

model : 'customer',
sorters : 'firstName',
storeId : 'customers',
data : [{
    id : 100,
    firstName : 'aaa'
}, {
    id : 101,
    firstName : 'sss'
}, {
    id : 102,
    firstName : 'rrrr'
}]

});

Now I need to modify this store to retrieve data from external server.Follwoing is the code i am using right now

var customers = new Ext.data.JsonStore({
        model : 'customer',

           proxy : {
            type : 'ajax',
            url:'http:sample.com',

            reader : {
                type : 'json',
                root : '',
            },                              
        },

        listeners : {

            datachanged : function() {

                customers.each(function(r) {
                    console.log('data in record is:'+ r.get('name'));
                });
            }
        },
    });

Now my doubt is that how to register this JSON store like the inital code to access the store from another viewcontroller file.

Thanks in advance

You can use the property:

storeId = "NameOfStoryID"

After filling your store you can, later on in your code, use this storeId to access the store (get the data, update it etc).

Example:

    var schouwLijstStore = new Ext.data.Store({

        model: "schouwLijst",
        storeId: "myStore",
        proxy: {
            type: 'ajax',
            url: 'php/json.php?t=list',
            reader: {
                type: 'json',
                root: 'list'
            },   
        },    
        autoLoad: true,
        listeners: {
            load: function() {

                               // Do things on load (sync to offline store for example)

            }

        }

    });

Now to access your store later on in the code you can use your storeID. For example to load it:

// Load myStore.load();

// Add item myStore.add({ id: *, value: * });

etc.
