public class XJSONDataSource extends DataSource
"scriptInclude"
transport
(sometimes called "JSONP") for cross-domain calls to JSON services.
To use this DataSource, provide the URL of the service as DataSource.dataURL
, and
provide fields
that describe the structure of the data you want to
extract from the service's response.
DataSource.recordXPath
and DataSourceField.valueXPath
can be used to extract
data from the JSON structure returned by the service. See
Client-Side Data Integration
for an overview of how to
control what parts of the JSON structure are included in the DSResponse
object, and
hence provided to DataBoundComponent
s that are bound to this DataSource.
This XJSONDataSource is really a subclass of DataSource with just a few property settings:
dataFormat : "json", dataTransport : "scriptInclude" callbackParam : "callback"
config, configOnly, factoryCreated, factoryProperties, id, scClassName

public static void setDefaultProperties(XJSONDataSource xJSONDataSourceProperties)
Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
