首先我们模拟一下后台传过来的数据,这里为了让代码清晰,数据就简单的模拟了一下

import bg3 from './image/bg3.png' constructor(props){ super (props) this .state = { ///这里 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方法循环出来

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