PHP开发框架Yii Framework教程（19） UI 组件 TreeView示例

PHP开发框架Yii Framework教程（19） UI 组件 TreeView示例2013-01-27 csdn mapdigitCTreeView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 ） ） ） ）））））;
