每个项都有唯一的标识符,用于区分不同的元素。 importReactfrom'react';constItem=({id,text})=>({text});constDraggableList=({items})=>({items.map(item=>(<Itemkey={item.id}id={item.id}text={item.text}/>))});exportdefaultDraggableList; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. ...
5. 管理状态和事件 为了让拖拽操作生效,我们需要在父组件中管理列表的状态,并提供一个moveItem函数来处理拖拽结束时的顺序更新。 importReact,{useState}from'react';importDraggableListfrom'./DraggableList';constApp=()=>{const[items,setItems]=useState([{id:1,text:'Item 1'},{id:2,text:'Item 2'},...

之所以表现像是按照 list 原始顺序展示，是通过在 sortedList.map 时根据当前 item 在 list 数组的索引 index 计算出其CSS的left和top 属性 拖拽实现 拖动增加特殊样式 首先，为最外层的容器 wrapper 绑定 ref 属性，方便在之后的事件方法中获取到该 DOM 节点，并将每个 li 元素的 draggable 属性的值设置为 true...
