【中文标题】使用 zend 框架显示树 dijit【英文标题】：Display a tree dijit using zend framework 【发布时间】：2010-04-02 12:09:12 【问题描述】：我正在尝试通过使用带有 zend 框架的 dijit 来显示类别和子类别的树。一直找不到好的例子。这就是我所拥有的：
基本上我得到了以下代码作为我的操作：
class SubcategoriesController extends Zend_Controller_Action
.....
public function loadtreeAction()
Zend_Dojo::enableView($this->view);
Zend_Layout::getMvcInstance()->disableLayout();
//Creating a sample tree of categories and subcategories
$a["cat1"]["id"] = "id1";
$a["cat1"]["name"] = "Category1";
$a["cat1"]["type"] = "category";
$subcat1 = array("id" => "Subcat1","name" => "Subcategory1" , "type" => "subcategory");
$subcat2 = array("id" => "Subcat12","name" => "Subcategory12" , "type" => "subcategory");
$a["cat1"]["children"] = array($subcat1,$subcat2);
$treeObj = new Zend_Dojo_Data('id', $a);
$treeObj->setLabel('name');
$this->view->tree = $treeObj->toJson();
....
在我看来：
<?php
$this->dojo()->requireModule('dojo.data.ItemFileReadStore');
$this->dojo()->requireModule('dijit.Tree');
$this->dojo()->requireModule('dojo.parser');
?>
<div dojoType="dojo.data.ItemFileReadStore" url="/Subcategories/loadtree" jsId="store"></div>
<div dojoType="dijit.tree.ForestStoreModel" jsId="treeModel" store="store" rootId="root" rootLabel="List of Categories" childrenAttrs="children" query="type:'category'"></div>
<div dojoType="dijit.Tree" model="treeModel" labelAttrs="ListOfCategories"></div>
它甚至似乎根本没有尝试加载树。
感谢任何帮助
【问题讨论】：
我不是 100% 确定，所以这是一个评论，以免一些纳粹投票反对我...您可能需要在您的视图/布局中添加类似的内容 $this->dojo() ->setLocalPath($this->baseUrl().'/scripts/dojo/dojo.js')->addStyleSheetModule('dijit.themes.tundra'); $this->dojo()->setDjConfig('parseOnLoad', 'true'); $this->dojo()->启用(); echo $this->dojo(); 【参考方案1】：首先您必须创建单独的操作。一个用于显示，另一个用于加载：
public function indexAction()
Zend_Dojo::enableView($this->view);
$this->view->dojo()->setDjConfigOption('parseOnLoad', true);
public function loadtreeAction()
//Creating a sample tree of categories and subcategories
$a["cat1"]["id"] = "id1";
$a["cat1"]["name"] = "Category1";
$a["cat1"]["type"] = "category";
$subcat1 = array("id" => "Subcat1","name" => "Subcategory1" , "type" => "subcategory");
$subcat2 = array("id" => "Subcat12","name" => "Subcategory12" , "type" => "subcategory");
$a["cat1"]["children"] = array($subcat1,$subcat2);
$treeObj = new Zend_Dojo_Data('id', $a);
$treeObj->setLabel('ListOfCategories');
$this->view->tree = $treeObj->toJson();
而且你不能忘记
setDjConfigOption('parseOnLoad', true)
在你的views/scripts/index.phtml中（如果你使用布局，一些部分必须放在里面，我让你这样做）：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<?php
$this->dojo()->enable();
$this->dojo()->requireModule('dojo.data.ItemFileReadStore');
$this->dojo()->requireModule('dijit.Tree');
$this->dojo()->requireModule('dojo.parser');
echo $this->dojo();
echo $this->dojo()->addStylesheetModule('dijit.themes.tundra');
?>
</head>
<body class="tundra">
<div id="content">
<div dojoType="dojo.data.ItemFileReadStore" url="http://194.79.142.38:1080/rbplm/public/home/index/loadtree" jsId="store"></div>
<div dojoType="dijit.tree.ForestStoreModel" jsId="treeModel" store="store" rootId="root" rootLabel="List of Categories" childrenAttrs="children" query="type:'category'"></div>
<div dojoType="dijit.Tree" model="treeModel" labelAttrs="ListOfCategories"></div>
</div>
</body>
</html>
而在 loadtree.phtmln 中：
<?php echo $this->tree ?>
