In this demo, the real data is required when one of the tree nodes is expanded. - </p> - <p> - The key thing to note is that all the lazy-loading logic (how to locate the data from the backend and so forth) is encapsulated - into the store functions. The dijit.Tree widget only knows about and uses the dojo.data.Read API interfaces to call to the store to - get items, test if child items are fully loaded or not, and to invoke the <i>loadItem()</i> function on items that are not yet fully - loaded but have been requested to be expanded into view. It has no knowledge of how the store actually goes and gets the data. - </p> - - <blockquote> - - <!-- - The store instance used by this demo. - --> - <div dojoType="dojox.data.demos.stores.LazyLoadJSIStore" jsId="continentStore" - url="geography/root.json"></div> - - <!-- - Display the toplevel tree with items that have an attribute of 'type', - with value of 'contintent' - --> - <b>Continents</b> - <div dojoType="dijit.Tree" id=tree label="Continents" store="continentStore" query="{type:'continent'}" - labelAttr="name" typeAttr="type"></div> - </blockquote> - -</body> -</html> |
