How to stop this text rotator on hover?

Question

Can someone help me. I want to add an option to pause on hover. How to do it? I found this script on the Internet. I don't know anything about programming. I can only implement. I will be grateful for any help. If this is not possible, please give me some suggestions. Where can I download a similar script with random display and pause on mouseover option.

style.css

body { text-align:center; background-color:#7F8C8D; color:#fff; margin:0}
#demo { list-style: none; color:#fff; }
#demo li { display: none; }

<ul id="demo">
  <li>Lorem ipsum dolor sit amet <a href="1.php">1</a></li>
  <li>Lorem ipsum dolor sit amet <a href="2.php">2</a></li>
  <li>Lorem ipsum dolor sit amet <a href="3.php">3</a></li>
</ul>

<script>
$(function(){
  $('#demo').textRotator({
   random : true,
   fadeIn : 1000,
   fadeOut : 500,
   duration : 5000,
   debug : false
   })
})
</script>
