vue實現簡單瀑布流佈局
阿新 • • 發佈:2020-03-11
vue簡單實現瀑布流佈局的一種方式(vue瀑布流元件),供大家參考,具體內容如下
vue中的瀑布流佈局元件
需求:圖片容器寬度固定,高度根據圖片自適應,圖片一行不能排列時候,換行依次從左往右排列。(瀑布流概念)
另外結合vue-lazy實現懶載入 ( npm i vue-lazyload --save-dev)
使用也很簡單,在需要懶載入的img標籤上將:src換成v-lazy
父元件傳遞資料:
waterfallData:[ { e_img: "test.jpg",// 圖片 e_intro: "描述資訊",u_img: "test.jpeg",// 標記圖 u_name: "開發者"},{ e_img: "test.jpg",e_intro: "描述資訊",u_name: "開發者"} ]
