        var script = "alert('Javascript is running');";
        return new JavaScriptResult() { Script = script };
       }

       and somewhere in a some view:

       <script>
         $(document).ready(function () {
             $("button").click(function () {
                $.getScript("/Home/RunJS");
             });
          });
        </script>

        <button>Use the button to run a JavaScript</button>
