DataSource Utility: DataSource.Local

If you are working with local array data, use the DataSourceArraySchema plugin to normalize and filter the data into a consistent format:

Use a DataSourceJSONSchema plugin to normalize JSON data:

YUI().use("datasource-local", "datasource-jsonschema", function(Y) {
    var myData = {
        "profile":{
            "current":160,
            "target":150
        },
        "reference": [
            {
                ...
            },
            {
                "category":"nutrition",
                "type":"intake",
                "fruit":[
                    {"name":"apple", "calories":70},
                    {"name":"banana", "calories":70},
                    {"name":"orange", "calories":90},
                ],
                "vegetables":[
                    {"name":"baked potato", "calories":150},
                    {"name":"broccoli", "calories":50},
                    {"name":"green beans", "calories":30}
                ]
            }
        ],
        "program": [
            ...
        ]
    },
    myDataSource = new Y.DataSource.Local({source:myData}),
    myCallback = {
        success: function(e){
            alert(e.response);
        },
        failure: function(e){
            alert("Could not retrieve data: " + e.error.message);
        }
    };

myDataSource.plug({fn: Y.Plugin.DataSourceJSONSchema, cfg: {
        schema: {
            resultListLocator: "reference[1].fruit",
            resultFields: ["name","calories"]
        }
    }});

myDataSource.sendRequest(null, myCallback);
});
