public static string ajaxLink(string $text, mixed $url, array $ajaxOptions=array ( ), array $htmlOptions=array ( ))
```

```php
echo CHtml::ajaxLink(
$text = 'Click me',
$url = '/',

**Example #1 : Ajax request using ajaxLink**
```php
//In view:
echo CHtml::ajaxLink(
'Test request', // the link body (it will NOT be HTML-encoded.)
array('ajax/reqTest01'), // the URL for the AJAX request. If empty, it is assumed to be the current URL.
array(
'update'=>'#req_res'
)
);
echo '<div id="req_res">...</div>';
//In controller
public function actionReqTest01() {
echo date('H:i:s');
Yii::app()->end();
}

//In view:
echo CHtml::ajaxLink(
'Test request', // the link body (it will NOT be HTML-encoded.)
array('ajax/reqTest01Loading'), // the URL for the AJAX request. If empty, it is assumed to be the current URL.
array(
'update'=>'#req_res_loading',
'beforeSend' => 'function() {
$("#maindiv").addClass("loading");
}',
'complete' => 'function() {
$("#maindiv").removeClass("loading");
}',
)
);
echo '<div id="req_res_loading">...</div>';
//In controller:
public function actionReqTest01Loading() {

echo date('H:i:s');
Yii::app()->end();
}
```
