es6在react中的应用
# 一、数组遍历显示
import React,{Component} from 'react';
class RepeatArray extends Component{
constructor() {
super();
}
render(){
const names = ['Alice', 'Emily', 'Kate'];
return (
<div>
{
names.map((name) =>{return <div>Hello, {name}!</div>;} )
}
</div>
);
}
}
export default RepeatArray;
@前端进阶之旅: 代码已经复制到剪贴板
# 二、ol与li的实现
import React,{Component} from 'react';
class RepeatLi extends Component{
render(){
return (
<ol>
{
this.props.children.map((child)=>{return <li>{child}</li>})
}
</ol>
);
}
}
class RepeatArray extends Component{
constructor() {
super();
}
render(){
return (
<div>
<RepeatLi>
<span>hello</span>
<span>world</span>
</RepeatLi>
</div>
);
}
}
export default RepeatArray;
