我尝试渲染10次,但它会产生某种错误,这是通常在这里解释的方法。我有新的反应,问题似乎是基本的,所以如果可以,请回答。感谢
loop = () => {
for (let i = 0; i<10;i++) {
return <UI title = "Default Title" discription = "the discription for this website is null init!" />;
}
}
render(){
return(
<div>
{this.loop}
</div>
);
}

这是一个尝试的策略...向数组添加元素(在此代码中为'square'),然后渲染该数组。在这种情况下,它是50个方格,但同样的想法。
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
var squares = [];
for(let i = 0; i< 50; i++){
squares.push(<div className='square'>{i}</div>);
}
return (
<div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h1 className="App-title">Welcome to React</h1>
</header>
<p className="App-intro">
I am coding!!
</p>
{squares}
</div>
);
}
}
export default App;
