How to call php controller action from javascript to get json data?

Question

I'm trying to call a controller action from javascript to get data in json format. I guess it should be pretty clear using $.getJSON function. But it doesn't work in my code. Is there anyone who can explain me what is wrong?

IndexController action

    public function jsonAction() 
    {
        $this->_disableView();

        $data[0]["name"] = "test";
        $data[0]["lat"] = 50.080746;
        $data[0]["long"] = 14.426373;

        echo json_encode($data);
    }

When I test it on url domain/index/json I see json as expected. Now the relevant script in document ready function:

    $.getJSON("index/json",function(data){
       alert("hello");
    });

But no alert is shown. In the console I can see

Uncaught TypeError: jQuery(...).asmSelect is not a function

I see that, but don't think this is the problem why the getJSON function doesn't get the data. If I move the code from action to get_data.php file in root and call "/get_data.php" in getJSON, it works good. — JanaMaha, Jun 16 '19 at 11:21
I know your problem was solved, but if you ever had such a problem, try chain your `getJSON` method with `fail` method, and log the error, see [this](https://api.jquery.com/jquery.getjson/) for more information about how to use `fail` method. — Ammar, Jun 16 '19 at 11:50
