CTreeView用来显示具有层次结构的数据，使用TreeView 通过设置Data属性。Data为具有下面结构的数组：
ext: string, 树节点的文本.
expanded: boolean,可选，表示该节点是否展开.
id: string, 可选，该节点ID.
hasChildren: boolean, 可选，缺省为False,当为True表示该节点含有子节点.
children: array,可选，子节点数组。.
htmlOptions: array, HTML选项。
到目前为止我们还没有介绍读取数据库，因此本例使用Hard Code的数据如下：
array(
'text' => '<a id="27" href="#">World:4</a>' ,
'id' => '27' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="1" href="#">Europa:3</a>' ,
'id' => '1' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="3" href="#">Germany:3</a>' ,
'id' => '3' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="15" href="#">Munich:0</a>' ,
'id' => '15' ,
'hasChildren' => false,
),
array(
'text' => '<a id="16" href="#">Stuttgart:0</a>' ,
'id' => '16' ,
'hasChildren' => false,
),
array(
'text' => '<a id="5" href="#">Berlin:0</a>' ,
'id' => '5' ,
'hasChildren' => false,
)
)),
array(
'text' => '<a id="2" href="#">Norway:3</a>' ,
'id' => '2' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="10" href="#">Stavanger:0</a>' ,
'id' => '10' ,
'hasChildren' => false,
),
array(
'text' => '<a id="12" href="#">Oslo:0</a>' ,
'id' => '12' ,
'hasChildren' => false,
),
array(
'text' => '<a id="11" href="#">Bergen:0</a>' ,
'id' => '11' ,
'hasChildren' => false,
))),
array(
'text' => '<a id="4" href="#">United Kingdom:2</a>' ,
'id' => '4' ,
'hasChildren' => true,
'children' =>
array(
array(
'text' => '<a id="13" href="#">London:0</a>' ,
'id' => '13' ,
'hasChildren' => false,
),
array(
'text' => '<a id="14" href="#">Manchester:0</a>' ,
'id' => '14' ,
'hasChildren' => false,
))),
array(
'text' => '<a id="7" href="#">Asia:3</a>' ,
'id' => '7' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="18" href="#">Japan:0</a>' ,
'id' => '18' ,
'hasChildren' => false,
),
array(
'text' => '<a id="20" href="#">China:0</a>' ,
'id' => '20' ,
'hasChildren' => false,
),
array(
'text' => '<a id="19" href="#">Indonesia:0</a>' ,
'id' => '19' ,
'hasChildren' => false,
)
)),
array(
'text' => '<a id="9" href="#">America:4</a>' ,
'id' => '9' ,
'hasChildren' => true,
'children' =>
array
(
array(
'text' => '<a id="23" href="#">Canada:0</a>' ,
'id' => '23' ,
'hasChildren' => false,
),
array(
'text' => '<a id="24" href="#">United States:0</a>' ,
'id' => '24' ,
'hasChildren' => false,
),
array(
'text' => '<a id="25" href="#">Mexico:0</a>' ,
'id' => '25' ,
'hasChildren' => false,
),
array(
'text' => '<a id="26" href="#">Argentina:0</a>',
'id' => '26' ,
'hasChildren' => false,
))),
array(
'text' => '<a id="8" href="#">Africa:2</a>' ,
'id' => '8' ,
'hasChildren' => true,
'children' =>
array(
array(
'text' => '<a id="22" href="#">Kenya:0</a>' ,
'id' => '22' ,
'hasChildren' => false,
),
array(
'text' => '<a id="21" href="#">Tanzania:0</a>' ,
'id' => '21' ,
'hasChildren' => false
)
)
)
)))));
这里为每个节点的文本都添加了一个链接，同时也演示了使用JQuery响应节点的点击事件，这是 通过客户端JavaScripts来实现的。
修改View定义
<?php
$cs=Yii::app()->clientScript;
$cs->registerScript('menuTreeClick', "
jQuery('#menu-treeview a').click(function() {
alert('Node #'+this.id+' was clicked!');
return false;
});
");
$this->widget('CTreeView',array(
'id'=>'menu-treeview',
'data'=>DataModel::getDummyData(),
'control'=>'#treecontrol',
'animated'=>'fast',
'collapsed'=>true,
'htmlOptions'=>array(
'class'=>'filetree'
)
));
?>
clientScript的registerScript用来做客户端定义JavaScripts。
