使用dropDownList请求后的renderPartial

Question

First, note that I have noticed that the common Yii widgets that have paginators, can go to any page without reloading the page, but just requesting it via AJAX and then changing the content of the already loaded page. Such behavior will completely satisfy my current needs.

I have a simple dropDownList in one of my views. What I'm trying to do is to change the content of the page without reloading the page, just like Yii's widgets.

Is that possible? How?

I tried doing something like this in my controller:

if(Yii::app()->request->isAjaxRequest){
    $this->renderPartial(.....);
}

and this in my dropDownList:

<?php
    echo CHtml::dropDownList('usage', 'cg', array(
        'd'=>'Daily',
        'm'=>'Monthly'
    ), array(
        'submit'=>array('admin/user', 'id'=>$user->iduser),
        'params'=>array('cg'=>'js:$(this).val()'),
        'options'=>array(
            Yii::app()->session['cg']=>array(
                'selected'=>true
            )
        )
    ));
?>

but the dropDownList keeps reloading the page.

Answer 1

I have done the following to reload content of div depending upon the selected value of dropDownList.Might be helpful to you.

echo CHtml::dropDownList('usage','cg',array('d'=>'Daily','m'=>'Monthly'),array('ajax'=>array(
        'type'=>'POST', //request type
        'url'=>$this->createUrl('controller/loadContent'), //url to call.
        'update'=>'#div_id',//div to update
        'data'=>array('cg'=>'js:this.value') 
        ))); 


public function actionLoadContent()
{
   ..........
   ..........
   $this->renderPartial('_ajaxContent', $data, false, true);
}
