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

import React, {Component} from 'react' ;
import logo from './logo.svg' ;
import './App.css' ;
import {Person,Twoway} from './Person/Person'
class App extends Component{
state={
persons:[{name: '小仙女' ,age: '18' },{name: '小玉' ,age: '18' },{name: '家璇' ,age: '18' }],
}
render(){
const listItems = this .state.persons.map((item,index) =>
<Person name={item.name} age={item.age} key={index} />
);
return (
<div className= "App" >
{listItems}
</div>
)
}
}
export default App;
