Display notification message when topic loads

I would like to display information/notification to the user in such a way that he/she will not omit this. On the other hand, I would like that he/she will be able to close it or it will be closed automatically.

Since that, I thought about using PNotify of Jquery.


%JQREQUIRE{"pnotify"}%

<script>
var showMessage
jQuery(function($) {

$( document ).ready(function() {
$.pnotify({
       text: "My very important message",
       type: 'info',
       animation: {
         effect_in: 'drop',
         options_in: {easing: 'easeOutBounce'},
         effect_out: 'drop',
         options_out: {easing: 'easeOutCubic'}
       },
       animation_speed: 700
    });
    return false;
  });

});
</script>

Could you help me on this or suggest different method of user notification, please?

Okay, seems that I found what was wrong. I corrected my example.
