Java yii：在js中传递参数

我试图通过点击按钮将所选id传递给js

我的代码如下：

array(
    'class'=>'CButtonColumn',
    'template'=>'{email}',
    'buttons'=>array
    (
        'email' => array
        (
            'label'=>'Send an e-mail to this user',
             'click'=>'function($data->userId){
                var y=confirm("Are you sure to send mail to this user?");
                if(y==true){
                    window.location="todoList/sendEmail/$data->userId";
                }
            }',

        ),

    ),
),

在这里，我无法在js中获取用户ID

我能在这里做什么？

好的，我自己找到了问题的答案。我的工作代码是：

 array(
'class'=>'CButtonColumn',
'template'=>'{email}',
'buttons'=>array
(   'email' => array
    (
        'label'=>'Send an e-mail to this user',
        'click'=>'function(){
          return confirm("Are you sure to send mail to this user?");

        }',
        'url'=>'Yii::app()->createUrl("todoList/sendEmail", array("id"=>$data->userId))',
    ),
),
