The CTreeView is used to display hierarchical data by using the TreeView by setting the DataSource property. Data is an array with the following structure:

Ext:string, the text of the tree node.

Expanded:boolean, optionally, indicates whether the node is expanded.

Id:string, optional, the node ID.

Haschildren:boolean, optional, false by default, when True indicates that the node contains child nodes.

Children:array, optional, sub-node array.

Htmloptions:array, HTML options.

So far we haven't introduced the read database, so this example uses hard code with the following data:

Array (' text ' = = ' id ' = ' + ', ' haschildren ' = ' + ', ' Children ' =>array (' text ' = ' = ' id ' = ' 1 ', ' HasChildren ' + true, ' children ' =>array (Array (' text ' = ' = ' id ' = ' 3 ', ' haschildren ' = ' = ' = ' Children ' Gt;array (' text ' = ' + ' id ' = ' + ', ' haschildren ' = false, '), Array (' text ' = ' = ' id ' = ' + ', ' haschild ') ren ' = ' and False, ' array (' text ' = ' + ' id ' = ' 5 ', ' haschildren ' = ' = ') '), Array (' text ' = ' = ' id ' = ' 2 ') , ' haschildren ' = true, ' Children ' =>array (' text ' = ' + ' id ' = ' + ', ' haschildren ' = false, '), Array (' Text ' = ' + ' id ' = ' + ', ' HasChildren ' and ' false ', array (' text ' = ' = ' id ' = ' one ', ' haschildren ' = False )), array (' text ' = = ' id ' = ' 4 ', ' haschildren ' = ' = ', ' Children ' =>array (' text ' = ' + ' id ' = ' = ') ', ' HasChildren ' and ' false, ', Array (' text ' = ' + ' id ' = ' + ', ' haschildren ' = False, ') '), Array (' text ' = = ') ' id ' = ' 7 ', ' Haschildren ' = True, ' Children ' =>array (Array (' text ' = = ' id ' = ' + ', ' haschildren ' = false, '), Array (' text ' = = ' id ' = ' + ', ' haschildren ' and ' = False ', ' Array (' text ' = ' + ' id ' = ' + ', ' haschildren ' = ' = False, ') '), Array ( ' text ' + = ' id ' = ' 9 ', ' haschildren ' = ' = ', ' Children ' =>array (Array (' text ' = ' = ' id ' = ' ", ' Hasch Ildren ' and False, ' array (' text ' = = ' id ' = ' + ', ' haschildren ' = false, '), Array (' text ' = = ' id ' = ' 2 5 ', ' haschildren ' = False,), array (' text ' = = ' id ' = ' + ', ' haschildren ' = ' = False, ') '), Array (' text ' = = ') ID ' = ' 8 ', ' haschildren ' = ' = ', ' Children ' =>array (Array (' text ' = ' + ' id ' = ' + ') ', ' haschildren ' = FA LSE,), array (' text ' = ' + ' id ' = ' + ', ' HasChildren ' + false)))));

This adds a link to the text for each node, and also shows the click events using the jquery response node, which is done through the client javascripts.

Modify the View definition

$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 ')) );? >

The ClientScript registerscript is used to do client-side definition javascripts.
