DataSource Utility: DataSource.IO
+ +
+
+
+
+ Accessing data from a server is easy with DataSource.IO, which uses the IO Utility to retrieve data over HTTP. A DataSchema plugin is used to normalize incoming data into a known format for consistency of usage by other components.

+ If your server returns JSON data, use a DataSourceJSONSchema plugin to parse the data against a schema that you provide:
+ +
YUI().use("datasource-io", "datasource-jsonschema", function(Y) { + var myDataSource = new Y.DataSource.IO({source:"ysearch_json_madonna.php"}), + myCallback = { + success: function(e){ + alert(e.response); + }, + failure: function(e){ + alert("Could not retrieve data: " + e.error.message); + } + }; + + myDataSource.plug(Y.Plugin.DataSourceJSONSchema, { + schema: { + resultListLocator: "ResultSet.Result", + resultFields: ["Title"] + } + }); + + // This request string will get appended to the URI + myDataSource.sendRequest("?output=json", myCallback); +});
On the other hand, a DataSourceXMLSchema plugin can be used to parse XML data coming from your server:
+ +
YUI().use("datasource-io", "datasource-xmlschema", function(Y) { + var myDataSource = new Y.DataSource.IO({source:"ysearch_xml_madonna.php"}), + myCallback = { + success: function(e){ + alert(e.response); + }, + failure: function(e){ + alert("Could not retrieve data: " + e.error.message); + } + }; + + myDataSource.plug(Y.Plugin.DataSourceXMLSchema, { + schema: { + resultListLocator: "result", + resultFields: [{key:"title", locator:"*[local-name() ='title']"}] + } + }); + + // This request string will be appended to the POST body + myDataSource.sendRequest("output=xml", myCallback, {method:"post"}); +});
