DataSource.Get uses the Get Utility to retrieve data, even cross-domain resources, via a dynamically created script node. A DataSchema plugin is used to normalize incoming data into a known format for consistency of usage by other components. Please note that your data resource must support a callback mechanism, which is a function wrapper around the returned data. The name of the callback function is passed to the resource via a query string parameter defined by the DataSource.Get attribute scriptCallbackParam.
Use a DataSourceJSONSchema plugin to parse the data against a schema that you provide:
YUI().use("datasource-get", "datasource-jsonschema", function(Y) {
var myDataSource = new Y.DataSource.Get({
source: "http://query.yahooapis.com/v1/public/yql?format=json&"
});
myDataSource.plug(Y.Plugin.DataSourceJSONSchema, {
schema: {
resultListLocator: "query.results.result",
resultFields: ["title"]
}
});
myDataSource.sendRequest({
request: 'q=select * from geo.states where place="United States"',
callback: {
success: function (e) { /* output to screen */ },
failure: function (e) { /* output to screen */ }
}
});
});
