DataSource's Pollable extension enables polling functionality on all your DataSource instances.
Include the datasource-pollable extension in your Y.use() statement to add the setInterval(), clearInterval(), and clearAllInterval() methods to all your DataSource instances.
YUI().use("datasource-function", "datasource-polling", function(Y) {
var myFunction = function() {
return new Date();
},
myDataSource = new Y.DataSource.Function({source:myFunction}),
request = {
callback: {
success: function(e){
Y.one("#demo_output_polling")
.setContent("At the tone the time will be: " +
Y.dump(e.response.results[0].toString()));
},
failure: function(e){
Y.one("#demo_output_polling")
.setContent("Could not retrieve data: " + e.error.message);
}
}
},
id = myDataSource.setInterval(1000, request); // Starts polling
myDataSource.clearInterval(id); // Ends polling
});
