PHP和JavaScript传递数组并使用dtree.js生成树

<html>
<head>
    <link rel="StyleSheet" href="include/dtree/dtree.css" type="text/css" />
    <script type="text/javascript" src="include/dtree/dtree.js"></script>
</head>
<body>
<?php
    include_once("./class.config.php");

$Result = $db->SelectSQL("select * from dept order by ParentDeptCode");

    while($temp = $db->Fetch($Result))
    {
        $Rs[]=$temp;
    }
    //如果PHP版本为5.2.0以上,直接用内置JSON函数
    //否则就使用第3方的JSON类库
    $str=json_encode($Rs);
    /*
    下面是调用js的方法
    注意:下面的写法是错误的:
    //echo '<script type="text/javascript">Test("'.$str.'");</script>';
    echo '<script type="text/javascript">Test('.$str.');</script>';
    */
?>

        d = new dTree('d');
        for(i=0;i<r.length;i++)
        {
            d.add(Number(r[i].DeptCode),Number(r[i].ParentDeptCode),r[i].DeptName,"DeptCode="+r[i].DeptCode);
            //d.add(i,-1+i,r[i].DeptName);
        }
        document.write(d);
</script>
</body>
</html>

在这里要注意,dtree.js的根节点索引为-1;
