JQuery 用户界面 : Part of a negative margins image disappears if I animate it

我正在使用 JQuery UI 制作动画。

我有一个图标，我想突出 div 的边缘，所以我使用负边距。

动画会调整 div 的大小并更改背景颜色。

但是，当我为 div 设置动画时，div 之外的图像区域(在负边距中)会在动画持续期间消失。

我已经调查过了，问题似乎出在 div 的大小调整上，而不是颜色变化或边距变化。例如。这取决于动画 CSS 宽度属性。

我也试过更改相关的 CSS 属性。比如固定图片的宽度，设置display: block，使用position: absolute，都没有用。

以前有人遇到过这个问题吗？

注意:目前在开发中，根本没有在 IE 中测试过。

最佳答案

只是想在此处和 Boagworld 上添加回复。

问题在于 jQuery 在执行动画时设置 overflow:hidden;。您的问题有两种解决方案:

(1) 在样式表中设置overflow:visible;。如果 jQuery 仍然覆盖它，您可以添加 !important。我不知道这是否会扰乱 jQuery 动画的方式，它可能会搞砸某些浏览器，但值得一试。

(2) 将您正在制作动画的 DIV 包装在另一个 DIV 标签中。为内部 DIV 提供足够的填充以容纳图标，然后为外部 DIV 标签设置动画。此选项添加了更多标记，但它不会干扰 jQuery 的工作方式，因此如果第一个选项出现错误，它保证可以正常工作。
