刷新后jQuery滑块不工作

Question

我的网站上有一个滑块。它在Firefox和IE等浏览器中运行良好，但在谷歌Chrome和Safari中却没有。刷新页面后图片不显示。我不知道为什么......

我的代码：

(function ($) {
    $.fn.jCarouselLite = function (o) {
        o = $.extend({
            btnPrev: null,
            btnNext: null,
            btnGo: null,
            mouseWheel: false,
            auto: null,
            speed: 500,
            easing: null,
            vertical: false,
            circular: true,
            visible: 3,
            start: 0,
            scroll: 1,
            beforeStart: null,
            afterEnd: null
        }, o || {});
        return this.each(function () {
            var b = false,
                animCss = o.vertical ? "top" : "left",
                sizeCss = o.vertical ? "height" : "width";
            var c = $(this),
                ul = $("ul", c),
                tLi = $("li", ul),
                tl = tLi.size(),
                v = o.visible;
            if (o.circular) {
                ul.prepend(tLi.slice(tl - v - 1 + 1).clone()).append(tLi.slice(0, v).clone());
                o.start += v
            }
            var f = $("li", ul),
                itemLength = f.size(),
                curr = o.start;
            c.css("visibility", "visible");
            f.css({
                overflow: "hidden",
                float: o.vertical ? "none" : "left"
            });
            ul.css({
                margin: "0",
                padding: "0",
                position: "relative",
                "list-style-type": "none",
                "z-index": "1"
            });
            c.css({
                overflow: "hidden",
                position: "relative",
                "z-index": "2",
                left: "23px"
            });
            var g = o.vertical ? height(f) : width(f);
            var h = g * itemLength;
            var j = g * v;
            f.css({
                width: f.width(1050),
                height: f.height(290)
            });
            ul.css(sizeCss, h + "px").css(animCss, -(curr * g));
            c.css(sizeCss, j + "px");
            if (o.btnPrev) $(o.btnPrev).click(function () {
                return go(curr - o.scroll)
            });
            if (o.btnNext) $(o.btnNext).click(function () {
                return go(curr + o.scroll)
            });
            if (o.btnGo) $.each(o.btnGo, function (i, a) {
                $(a).click(function () {
                    return go(o.circular ? o.visible + i : i)
                })
            });
            if (o.mouseWheel && c.mousewheel) c.mousewheel(function (e, d) {
                return d > 0 ? go(curr - o.scroll) : go(curr + o.scroll)
            });
            if (o.auto) setInterval(function () {
                go(curr + o.scroll)
            }, o.auto + o.speed);

            function vis() {
                return f.slice(curr).slice(0, v)
            };

            function go(a) {
                if (!b) {
                    if (o.beforeStart) o.beforeStart.call(this, vis());
                    if (o.circular) {
                        if (a <= o.start - v - 1) {
                            ul.css(animCss, -((itemLength - (v * 2)) * g) + "px");
                            curr = a == o.start - v - 1 ? itemLength - (v * 2) - 1 : itemLength - (v * 2) - o.scroll
                        } else if (a >= itemLength - v + 1) {
                            ul.css(animCss, -((v) * g) + "px");
                            curr = a == itemLength - v + 1 ? v + 1 : v + o.scroll
                        } else curr = a
                    } else {

                        $((curr - o.scroll < 0 && o.btnPrev) || (curr + o.scroll > itemLength - v && o.btnNext) || []).addClass("disabled")

    function css(a, b) {
        return parseInt($.css(a[0], b)) || 0
    };

    function width(a) {
        return a[0].offsetWidth + css(a, 'marginLeft') + css(a, 'marginRight')
    };

    function height(a) {
        return a[0].offsetHeight + css(a, 'marginTop') + css(a, 'marginBottom')
    }
})(jQuery);

谢谢！
