JQuery UI:如果我为其设置动画,则部分负边距图像会消失

ric*_*ick 5 css jquery png jquery-ui

我正在使用JQuery UI进行动画制作.

我有一个图标,我想在div的边缘伸出,所以我使用负边距.

动画调整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neg margin中)会在动画持续时间内消失.

我调查了它,看来问题来自div的调整大小,而不是颜色变化或边际变化.例如.这取决于动画CSS宽度属性.

我也试过改变相关的CSS属性.例如,固定图像的宽度,设置display:block并使用position:absolute,其中没有一个工作.

以前有人遇到过这个问题吗？

只是想在这里以及Boagworld上添加回复.

问题在于jQuery设置overflow:hidden;正在进行动画制作.您的问题有两种解决方案:

(1)overflow:visible;在样式表中设置.!important如果jQuery仍在覆盖它,您可以添加它.我不知道这是否会破坏jQuery的动画效果,它可能搞砸了一些浏览器,但它值得一试.

(2)将您正在动画的DIV包装在另一个DIV标签内.为内部DIV提供足够的填充以容纳图标,然后为外部DIV标记设置动画.这个选项增加了更多的标记,但它并没有弄乱jQuery如何处理事情,所以如果第一个结果是错误的,它肯定会起作用.
