是否可以在zend控制器功能中打印消息而不使用视图？

Question

I don't know if this question is duplicated or not. I'm a totally newbie in zend. I want to use an ajax event and when i call the controllername/myfunctionfromthecontroller in url , i want to return a message . I tried this :

$.ajax({
    url: "/location/testare",
    type: "POST",
    data: post_array,
    success: function (data, textStatus, jqXHR) {
        //data - response from server
    },
    error: function (jqXHR, textStatus, errorThrown) {

    }
});

and in the controller :

public function testareAction()
{ 
    $this->view->String = 'hello world';
}

the firebu return me this : "500 Internal Server Error". Can someone help me with this ?

I use this in Zend Framework 1. MaiKaY's solution seems to be fore ZF2:

In the controller, before the output, set the header to expose json output:

    $this->getResponse()->setHeader('Content-Type', 'application/json');

Disable all the layout stuff:

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

And if you want to use echo \Zend_Json::encode($yourOutput); instead of using a view for the json, use this:

    $this->_helper->viewRenderer->setNoRender(true);
