I am new to zend framework, I am working on ajax based tabs in zend framework. On clicking a tab I want am calling an action, I want to get rendered content(content rendered in respective view) to send it as response.

Not sure what you want exactly, but you can disable rendering of the layout in your action and have only action view script rendered, e.g.

public function exampleAction() {

    if ($this->getRequest()->isXmlHttpRequest()) {

        $this->_helper->layout->disableLayout();

        $this->view->var = 'some var';
    } else {
        throw new Exception('Not an ajax requrests');
    }
}

View:

<a href="#" class="tab">Click</a>
<div id="content"></div>

JS:

$('.tab').click(function() {
    $.get('/controller/ajax', function(data) {
        $('#content').html(data);
    });
});

Controller:

public function ajaxAction()
{
    echo 'string';
    exit;
}

You just have to add exit; in your action so it doesn't try to render the layout again.

public function yourAction() {
        // get response and layout 
        $response                        = $this->getResponse();
        $layout                          = $this->_helper->layout();

        // rendering action's template      
        $this->render( 'template' );   

        // setting content, don't remember to echo $this->Layout()->content in the layout script                           
        $layout->content                 = $response->getBody();

        //  here you can get your rendered content, and do something with it 
        $renderedContent                 = $layout->render( 'layout' );  

        // you have to clean response otherwise will be automaticaly sent
        $response->clearBody();                                         
}

try this, also make sure to add an exit at the end

$this->view->assign(array('name' => 'my name', 'msg' => 'my message'));
echo $this->view->render('message/display.phtml');
exit;

then in the .phtml file simply call

<?php echo $this->msg; ?>
