Change text inside <script> tag?

Change text inside <script> tag?

I need to change some text inside a script tag when I click a button on my page. Is there a way to change "autoPlay: 200" to "autoPlay: 0" when I click an element id="button1"? The script I want to change is included below:
  1.     <script type="text/javascript">
            $(document).ready(function() {
                $("#featureCarousel").featureCarousel({
                    topPadding: 10,
                    sidePadding: 5,
                    autoPlay: 200,
                    counterStyle: 1
               });
            });
        </script>
