jquery - Jquery - 在 IE 中不按负百分比设置动画

Question

所以我修改了这个 Supersized 插件。我添加了让 div 进出动画的功能。在 Firefox、Safari 和 Chrome 中，工作正常。在 IE7 及更高版本中，它并不好。有些幻灯片有动画，有些没有。有人有什么想法吗？代码片段和链接如下：

    if (base.options.slide_links){
        // Slide marker clicked
        $(vars.slide_list+'> li').click(function(){

            index = $(vars.slide_list+'> li').index(this);
            targetSlide = index + 1;

            slide1 = index + 1; //Slide clicked
            slide2 = vars.current_slide + 1; //Current slide

            //User click
            if(slide1 != undefined || slide1 != null || slide1 != '') {
                if (slide1 == 1 && slide2 == 2) {
                    $('#homeslide3').hide();
                    $('#homeslide4').hide();
