* @class YAHOO.ext.View
* @extends YAHOO.ext.util.Observable
* Create a &quot;View&quot; for an element based on a data model or UpdateManager and the supplied DomHelper template.
* This class also supports single and multi selection modes. &lt;br&gt;
* Create a data model bound view:
&lt;pre&gt;&lt;code&gt;
var dataModel = new YAHOO.ext.grid.XMLDataModel(...);
var view = new YAHOO.ext.View('my-element',
'&amp;lt;div id=&quot;{0}&quot;&amp;gt;{2} - {1}&amp;lt;/div&amp;gt;', // auto create template
dataModel, {
singleSelect: true,
selectedClass: 'ydataview-selected'
});
// listen for node click?
view.on('click', function(vw, index, node, e){
alert('Node &quot;' + node.id + '&quot; at index: ' + index + ' was clicked.');
});
// load XML data
dataModel.load('foobar.xml');
&lt;/code&gt;&lt;/pre&gt;
For an example of creating a JSON/UpdateManager view, see {@link YAHOO.ext.JsonView}.
* &lt;br&gt;&lt;br&gt;
* &lt;b&gt;</span><span class="hl-inlinedoc">Note:</span><span class="hl-comment"> The root of your template must be a single node. Table/row implementations may work but are not supported due to
* IE's limited insertion support with tables and Opera's faulty event bubbling.&lt;/b&gt;
* @constructor
* Create a new View
* @param {String/HTMLElement/Element} container The container element where the view is to be rendered.
* @param {String/DomHelper.Template} tpl The rendering template or a string to create a template with
* @param {DataModel} dataModel The bound data model
* @param {Object} config The config object
