会jquery大神的进来！！！！！
这是一个jquery插件，但是在一个页面只能调用一次，不能多次调用，怎么改才能多次调用啊，大家帮看看，
这是js插件代码：
//滚动插件
(function ($) {
$.fn.extend({
Scroll: function (opt, callback) {
//参数初始化
if (!opt) var opt = {};
var _this = this.eq(0).find("ul:first");
var lineH = _this.find("li:first").height(), //获取行高
line = opt.line ? parseInt(opt.line, 10) : parseInt(this.height() / lineH, 10), //每次滚动的行数，默认为一屏，即父容器高度
speed = opt.speed ? parseInt(opt.speed, 10) : 500, //卷动速度，数值越大，速度越慢（毫秒）
timer = opt.timer ? parseInt(opt.timer, 10) : 3000; //滚动的时间间隔（毫秒）
if (line == 0)
line = 1;
var upHeight = 0 - line * lineH;
//滚动函数
scrollUp = function () {
//alert(_this.html(""));
_this.animate({
marginTop: upHeight
}, speed, function () {
for (i = 1; i <= line; i++) {
_this.find("li:first").appendTo(_this);
}
_this.css({ marginTop: 0 });
});
}
//鼠标事件绑定
_this.hover(function () {
clearInterval(timerID);
}, function () {
timerID = setInterval("scrollUp()", timer);
}).mouseout();
}
})
})(jQuery);
