* @extends Roo.View
* Shortcut class to create a JSON + {@link Roo.UpdateManager} template view. Usage:
<pre><code>
-var view = new Roo.JsonView("my-element",
- '<div id="{id}">{foo} - {bar}</div>', // auto create template
- { multiSelect: true, jsonRoot: "data" }
-);
+var view = new Roo.JsonView({
+ container: "my-element",
+ tpl: '<div id="{id}">{foo} - {bar}</div>', // auto create template
+ multiSelect: true,
+ jsonRoot: "data"
+});
// listen for node click?
view.on("click", function(vw, index, node, e){
"</div><hr />"
);
-var moreView = new Roo.JsonView("entry-list", tpl, {
+var moreView = new Roo.JsonView({
+ container : "entry-list",
+ template : tpl,
jsonRoot: "posts"
});
moreView.on("beforerender", this.sortEntries, this);
text: "Loading Blog Entries..."
});
</code></pre>
+*
+* Note: old code is supported with arguments : (container, template, config)
+*
+*
* @constructor
* Create a new JsonView
- * @param {String/HTMLElement/Element} container The container element where the view is to be rendered.
- * @param {Template} tpl The rendering template
+ *
* @param {Object} config The config object
+ *
