首先我們模擬一下后臺傳過來的數(shù)據(jù),這里為了讓代碼清晰，數(shù)據(jù)就簡單的模擬了一下

import bg3 from './image/bg3.png'constructor(props){ super(props) this.state = { ///這里 list:[ { id:1,img:bg3}, { id:2,img:bg3}, { id:3,img:bg3}, { id:4,img:bg3}, { id:5,img:bg3}, ], /// }} |
然后在使用map方法循環(huán)出來

{ this.state.list.map((item,key) => { return ( <div className="winfor" onClick={() => console.log(item.id)}> <img src={item.img} className="winforimg" /> </div> ) })} |
補充：React 循環(huán)列表
