我对一页的一般幻灯片动画有疑问。我花了半天时间试图解决这个问题,我就放弃了。也许更熟悉 jQuery 的人能够发现这个问题。当您尝试在最后 2 个子页面(div)之间切换时存在问题:图库和联系人... 基本上该页面是由 div(类似于子页面)组成的,它们根据用户的选择上下滑动。这是实际页面:(http://4play.dj/home.html对不起,我猜系统不允许 .dj 域)。该页面在 IE 中运行良好,这很奇怪,因为通常问题是另一种方式。我创建了一个 fiddle: link,但由于某种原因它对我不起作用。任何帮助将不胜感激。非常感谢您提前。

下面的jQuery代码(代码在这里:对不起,但问题可能到处存在,我一行一行地走了10000次,一无所获):

    ;(function( $ ){

        var $scrollTo = $.scrollTo = function( target, duration, settings ){

        // Returns the element that needs to be animated to scroll the window.
        // Kept for backwards compatibility (specially for localScroll & serialScroll)
        $scrollTo.window = function( scope ){
            return $(window)._scrollable();

 window.onload = function () {
 resizePanel()
 }

希望这会起作用,因为当您实际调整页面大小时该功能正在工作
