仿小米有品 轮播图组件

公司UI提供的精钢区的轮播图样式如上图所示：

本着简单高效的编程习惯，我打开了百度……

由于公司现在使用的是 uniapp，所以先从DCLOUD 插件市场查找。

找到一个堆叠轮播组件：

最终样式调整之后展示的效果如下图所示：

代码如下：

//组件导入:
import blackmonthSwiper from "@/components/blackmonth-swiper/index.vue"
//组件注册：
components:{
	blackmonthSwiper
},
//组件数据处理：
swiperList: [{
	type: 'image',
		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big84000.jpg'
	}, {
		type: 'image',
		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big37006.jpg',
	}, {
		type: 'image',
		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big39000.jpg'
	}, {
		type: 'image',
		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big10001.jpg'
	}, {
		type: 'image',
		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big25011.jpg'
	}, {
		type: 'image',

	}, {
		type: 'image',

	}]

轮播组件包含手动切换与自动轮播两种形式
