jquery滑块在IE上无法正常工作

Question

我们在我们网站上使用的jquery滑块在IE上无法正常工作。下面的标记正在加倍或者在IE上追加两次，不确定下面代码中的哪一行导致它或IE中不支持。我将不胜感激。

     <li><a data-slidetarget="' + (index + 1) + '" href="#"></li>

以下是滑块上使用的完整代码：

     (function($) {
        $.fn.shaliSlider = function(options) {

            if (!this.length) { return this; }

            var opts = $.extend(true, {}, $.fn.shaliSlider.defaults, options);

            this.each(function() {
                var $this = $(this),
                    $itemContainer = $this.find(opts.itemContainer),
                    $items = $itemContainer.find(opts.item),
                    $previous = $this.find(opts.previousButton),
                    $next = $this.find(opts.nextButton),
                    slideWidth = $items.first().width(),
                    total = $items.length,
                    current = 1,
                    waitTime = opts.waitTime,
                    userWaitMultiplier = 1.5,
                    $paginationList,
                    timer;


                if (opts.usePagination) {
                    $paginationList = $("<ul>", {
                        id: opts.paginationId,
                        "class": opts.paginationClass
                    });

                    $items.each(function(index) {
                        $paginationList.append('<li><a data-slidetarget="' + (index + 1) + '" href="#"></li>');
                    });

                    $paginationList.delegate('a', 'click', function(event) {

                            slideTarget = parseInt($this.data("slidetarget"), 10);

                        changeSlide(slideTarget);
                        event.preventDefault();
                    });

                     $this.append($paginationList);
                }

                function timerTrigger() {
                    changeSlide(current + 1, true);

                function changeSlide(slide, fromTimer) {

                    $itemContainer.stop(true, true).animate({
                        marginLeft: -((current - 1) * slideWidth)
                    }, "slow", opts.usePagination ? function(){

                            .removeClass(opts.paginationActiveClass)
                            .eq(current-1)

                } else {
