This file is a demo of the FlickrStore, a simple wrapper to the public feed service
|
|
of Flickr. This just does very basic queries against Flickr and loads the results
|
|
into a list viewing widget.

DEMO: FlickrStore Search

Description:
|
|
</h3>
|
|
<p>
|
|
This simple demo shows how services, such as Flickr, can be wrapped by the datastore API. In this demo, you can search public
|
|
Flickr images through a simple FlickrStore by specifying a series of tags (separated by spaces) to search on. The results
|
|
will be displayed below the search box. This demo is the same as the example demo provided in dojox/data/demos/demo_FlickrStore.html,
|
|
except that all the interactions are implemented via Wire instead of a script that runs at dojo.addOnLoad().
|
|
</p>
|
|
<p>
|
|
For fun, search on the 3dny tag!
