Trying to call action method from jquery function

Question

I am new to both MVC and JQuery, but this should not really be that difficult. When I call the function, nothing happens. I put an alert box in the function, and I can see that the function is called.

I found this, but it did not help me: Calling ASP.NET MVC Action Methods from JavaScript

This is my script:

<script type="text/javascript">
    function oKButtonPressed(){    
        jQuery.ajax({
            type: "POST",
            url: "@Url.Action("MessageToPatient", "StartScreen")"
        });
    };
</script>

MessageToPatient is the name of the action method. StartScreen is the name of the controller.

Can you see something obvious I'm missing? Otherwise, it might be something with my MVC code.

Put a breakpoint inside your controller action to see if the action actually gets called. — ataravati

By the way, you're not passing any data with your ajax post. — ataravati

Hmm, I mean all I want to do is call the action method, without any data passed. — hellogoodnight

You are Getting/posting to an action using jQuery.Ajax.

You can return data to this jQuery, but an MVC view will not be rendered as if it was just a normal request. You have to process the returned data in some way.

See this for example: http://www.itorian.com/2013/02/jquery-ajax-get-and-post-calls-to.html?m=1

Ok, thanks. Well if you were to just call an action method that renders a view with a button click, how would you do it?

Try googling a beginner's MVC tutorial, it'd be quicker than asking q's on here.
