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, May 24 '15 at 14:59
By the way, you're not passing any data with your ajax post. — ataravati, May 24 '15 at 15:02
Hmm, I mean all I want to do is call the action method, without any data passed. — hellogoodnight, May 24 '15 at 15:05
And, if the action method is called, then what's the problem? — ataravati, May 24 '15 at 15:09
Sorry, I am really new to this. Anyway, I changed it to "GET" with the same result. I also removed the whole line, same thing. — hellogoodnight, May 24 '15 at 15:10
But, you don't even need to use jQuery if it's GET request. And, you say the action is called. Then, what's the problem? — ataravati, May 24 '15 at 15:10
Hmm, ok, but I saw that in every answer when I googled it. I just wanted to call an action method. Anyway, this is my action method: public ViewResult MessageToPatient() { return View(); } — hellogoodnight, May 24 '15 at 15:11
You can't return a View when using ajax. I'd suggest that you read a little bit more about Ajax, asp.net MVC, and jquery before starting to code. — ataravati, May 24 '15 at 15:13
Also check the positions where single quotes and double quotes. — Adersh M, May 25 '15 at 05:04

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? – hellogoodnight May 24 '15 at 15:25
Try googling a beginner's MVC tutorial, it'd be quicker than asking q's on here. – ozz May 24 '15 at 15:29
