Textarea and button

How can I connect the results of a button with a textarea to display them??

This is my code




<?php $this->widget('zii.widgets.grid.CGridView', array(

	'dataProvider'=>$dataProvider,

	

	'columns'=>array(

		'ACCESSO_ID',

		/*array(            // display 'author.username' using an expression

            'name'=>'ACCESSO_ID',

            'value'=>'$data->ACCESSO_ID',

        ), */


		'USER_NAME',

		'PASSWORD',

		//'ANAGRA_ANAGRA_ID',

		array(  

            'name'=>'ANAGRA_ANAGRA_ID',

      		'value'=>'anagrafe::model()->FindByPk($data->ANAGRA_ANAGRA_ID)->NOME',

        ),

        array(  

            'name'=>'Cognome',

      		'value'=>'anagrafe::model()->FindByPk($data->ANAGRA_ANAGRA_ID)->COGNOME',

        ),

		//'SSO_USER',

		//'APPROVATO',

		

        

		array(

     			'class'=>'CButtonColumn',

     			'template'=>'{ruolo}',

     			'buttons'=>array(

         		 			 'ruolo'=>array(

              				 'label'=>'Assegna Ruolo ',

               	  			 'url'=>'Yii::app()->createUrl("/ruoli/create", array("id" => $data->ACCESSO_ID))',

               	  			 

           					),

     					),

  			 ),

  		),	 

)); ?>




When i click a button ‘Assegna Ruolo’ i redirect to another page in which i visualize the role of single person…

how can i visualize thiese result in a control??

Textarea or another???

javascript which means at the $htmlOptions of the button ‘onclick’=>‘what you want to do in jquery code prefered’ :)

What i can search?I javascript that add a value in a textarea???

I have a version of yii that don’t use jquery…
