According to the documentation, you need to add this:
<script type="text/javascript">
$(function () {
$('#js-news').ticker({
htmlFeed: false,
ajaxFeed: true,
feedUrl: 'PUT THE URL OF THE RSS FEED HERE - e.g. http://example.com/rss.xml',
feedType: 'xml'
});
});
</script>
Also, keep in mind your RSS feed MUST be on the same domain as your site. Here are all the options of the plugin:
$(function () {
$('#js-news').ticker(
speed: 0.10, // The speed of the reveal
ajaxFeed: false, // Populate jQuery News Ticker via a feed
feedUrl: false, // The URL of the feed
// MUST BE ON THE SAME DOMAIN AS THE TICKER
feedType: 'xml', // Currently only XML
htmlFeed: true, // Populate jQuery News Ticker via HTML
debugMode: true, // Show some helpful errors in the console or as alerts
// SHOULD BE SET TO FALSE FOR PRODUCTION SITES!
controls: true, // Whether or not to show the jQuery News Ticker controls
titleText: 'Latest', // To remove the title set this to an empty String
displayType: 'reveal', // Animation type - current options are 'reveal' or 'fade'
direction: 'ltr' // Ticker direction - current options are 'ltr' or 'rtl'
pauseOnItems: 2000, // The pause on a news item before being replaced
fadeInSpeed: 600, // Speed of fade in animation
fadeOutSpeed: 300 // Speed of fade out animation
);
});
