199767f8919635c4928607450d9e0abb932109ceToomas Soome <p>DataSource.Get uses the Get Utility to retrieve data, even cross-domain resources, via a dynamically created script node. A <a href="../dataschema/">DataSchema</a> 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`.</p>
