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：

[dcloud堆叠轮播组件：https://ext.dcloud.net.cn/plugin?id=1250][dcloud_https_ext.dcloud.net.cn_plugin_id_1250]

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',
    		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big21016.jpg'
    	}, { 
    		type: 'image',
    		url: 'https://ossweb-img.qq.com/images/lol/web201310/skin/big99008.jpg'
    	}]

轮播组件包含手动切换与自动轮播两种形式
