Refresh data

Data sets can reload their data at a specified interval expressed in milliseconds. This can be handy when the data at a given URL changes periodically.

To tell a data set to load at a given interval, pass the optional loadInterval option when calling the XMLDataSet constructor, and make sure the useCache option is set to false:

// Load the data every 10 seconds. Turn off the cache to  make sure we get it directly from the server.
var dsPhotos = new  Spry.Data.XMLDataSet("/photos.php?galleryid=2000", "/gallery/photos/photo", { useCache:
 false, loadInterval: 10000 });

You can also turn on this interval loading programmatically with the startLoadInterval() method, and stop it with the stopLoadInterval() method.

dsPhotos.startLoadInterval(10000); // Start loading data every 10 seconds.
...
dsPhotos.stopLoadInterval(); // Turn off interval loading.
