Question

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。

我已经调查过了，看来问题来自于调整div的大小，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。

我也尝试过更改相关的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。

之前有人遇到过这个问题吗？

Answer 1

只想在这里以及Boagworld上添加回复。

问题在于jQuery在设置动画时设置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）将您正在制作动画的DIV包裹在另一个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，但它并没有搞乱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。

Answer 2

我也有这个问题，无法使用容器解决方案，因为我的元素有边框。 @dougoftheabaci在正确的轨道上，但是jQuery在元素的样式上设置了overflow:visible，因此样式表将不起作用（即使使用!important）。

但我找到了this trick，效果很好。

通过一些快速测试，您可以工作   通过设置溢出来解决这个问题   在animate（）调用之后：

$（myEl）.animate（...）
  .css（'溢出'，'可见'）;

Answer 3

您可以在设置动画之前尝试使用以下内容

$(this).dequeue().stop().
animate({backgroundColor: "#fff", marginLeft: "0",width: "29%", paddingBottom:"10px"}

JQuery UI：如果我为其设置动画，则部分负边距图像会消失
