Yii中的Prinout Extension，如何删除页眉，页脚和锚标签？

This is my view code

<?php 
$this->widget('application.extensions.print.printWidget', array(                   
               'cssFile' => 'print.css',
               'coverElement' => '#wrapper',
               'printedElement'=>'#summary',
               )
             ); 
?>
<div id="summary">

<?php $this->widget('zii.widgets.CDetailView', array(
'data'=>$model,
'attributes'=>array(
    'name',
    'date_created',
    'medical_treatment',
    'remarks',
),
)); ?>
<br><br>
<center>____________________________</center>
<center>Doctor's Signature</center>
</div>

my controller/action

     public function actionPrescription($id) 
{
    $this->render('printprescription', array(
    'model'=>$this->loadModel($id),
    ));
}

I want to print only the content of div id="summary" the extension does let me do it but it prints out the entire page first with the header and footer

I thought the coverElement could remove it but I guess not?

can anyone help?

Adding print media in CSS should have helped. You can try adding selectors for header and footer directly into extension code.

    echo CHtml::css("
        .printWidgetScreenCover {display: none;}
        .printWidgetPrintedElement {display: block; margin: 20px;}
        #header {display: none;}
        #footer{display: none;}
        ",
        "print"
    );
