jquery 每个选项卡 都有一个轮播图 第一个选项卡轮播图 轮播完后去执行第二个隐藏的轮播图了
你不想执行第二个,就要在代码中,增加控制。用幻灯片的div id限定范围。
比如:$("#slideshow1 img") //第一个。$("#slideshow2 img")//第二个
Flutter实现堆叠式卡轮播效果
在本博客中,我们将探讨Flutter中的堆叠式卡轮播。 我们还将实现一个演示程序,并学习在您的flutter应用程序中使用 stacked_card_carousel 包创建一个带有垂直轮播的堆叠卡。
用于创建带有堆叠卡片的垂直轮播的小部件。 下面的演示视频显示了如何在Flutter中创建带有垂直旋转木马的堆叠卡。 它显示了在您的flutter应用程序中如何使用stacked_card_carousel软件包来使用堆叠式卡轮播。 它显示了垂直圆盘传送带滑动卡的列表,所有卡向上滑动并堆叠,称为堆叠式卡传送带。 它会显示在您的设备上。
堆叠式卡轮播的一些属性是:
在lib文件夹中创建一个名为style_card.dart的新dart文件。
首先,我们创建StyleCard类,将在后续的DEMO中调用它
我们将制作一个 card 控件. 在card控件中, 我们加入一个elevation 属性和一个column控件。 在column中, 我们加入一个container用于包含image, title 和 description. 然后在stacked_card_demo页面中使用它。
在lib文件夹中创建一个新的名为stacked_card_demo.dart的dart文件。
现在,我们将创建一个styleCards列表,并在其中添加一个StyleCard类。
我们创建了八个卡片控件,并在其中添加了image,title和description。 程序运行后,我们将看到一个卡片列表, 当用户向上滑动时,所有卡片都将堆叠在一起; 当用户向下滑动时,卡片都将回到原始位置;
效果如下:

这种情况只能自己绘图,或者使用图片,现在介绍怎么绘图,先展示一下效果图:
第一步:先创建一个绘图类,以支持椭圆形角
