我有一些小问题，我有一个插件可以获取我的推特提要，效果很好！但是我希望它滚动浏览
用于 twitter fetch 的 JS 插件/我也在这里添加了 vticker

JS 我用来调用一切
// Setup twitter feed
function dateFormatter(date) {
return date.toString().split(' ')[1] + ' ' + date.getFullYear() % 100;
}
var twitterConfig = {
"id": '489803450398433282',
"domId": 'twitterFeed',
"maxTweets": 6,
"enableLinks": true,
"dateFunction": dateFormatter
};
twitterFetcher.fetch(twitterConfig);
$(document).ready(function() {
$('#twitterFeed').vTicker();
});
也许我需要手动添加并调用
$('#twitterFeed').vTicker();
在插件中？它永远不会被更新，所以如果需要的话，不要介意它直接在代码中
提前谢谢各位
