How to create Ext.data.Store from an unusual JSON store?

Question

I have this JSON store but it`s not coded correctly. What is the correct syntax for it?

Ext.define(\'MA.store.Language\', {
extend : \'Ext.data.Store\',
fiel

So you want to use your unusual JSON anyway. In this case you can solve your problem by defining your own reader. Like this:

Ext.define('MA.reader.Language', {
    extend: 'Ext.data.reader.Json',
    alias: 'reader.Language',
    read: function (response) {
        var data = [];
        for (var i in response[0])
            data.push({
                id: i,
                'name': response[0][i]
            });
        return this.callParent([data]);
    }
});

Ext.define('MA.store.Language', {
    extend: 'Ext.data.Store',
    fields: [{
        name: 'id'
    }, {
        name: 'name'
    }],
    data: [{
        "aa": "Afar",
        "ab": "Abkhazian",
        "ace": "Achinese",
        "ach": "Acoli",
        "ada": "Adangme",
        "ady": "Adyghe",
        "ae": "Avestan",
        "af": "Afrikaans",
        "afa": "Afro-Asiatic Language",
        "afh": "Afrihili",
        "ain": "Ainu",
        "ak": "Akan"

    }],
    proxy: {
        type: 'memory',
        reader: {
            type: 'Language'
        }
    }
});

var store = Ext.create('MA.store.Language', {
    storeId: 'Language'
});

var cc = Ext.widget('combo', {
    xtype: 'combo',
    name: 'language',
    fieldLabel: 'Language',
    store: 'Language',
    queryMode: 'local',
    displayField: 'name',
    valueField: 'id',
    typeAhead: true,
    forceSelection: true
});

cc.render(Ext.getBody());
