我正在尝试将组件代码和容器代码分开。
我知道Main.js中的按钮“隐藏”被按下时会调用MainContainer中的函数handleHide()
,因为位于Alert
函数中的handleHide()
起作用了。
所以基本上,这是不透明性无法通过props更改或我丢失了一些东西的问题。
下面是我的Main.js文件(组件)
import React from 'react'
const styles = {
transition: 'all 1s ease-out'
}
export class Main extends React.Component {
render () {
return (
<div>
<nav>
<div className='nav-wrapper'>
<a href='/' className='brand-logo'>Todays’ EDM</a>
<ul id='nav-mobile' className='right hide-on-med-and-down'>
<li><a href='sass.html'>Music</a></li>
<li><a href='badges.html'>Playlists</a></li>
<li><a href='collapsible.html'>News</a></li>
</ul>
</div>
</nav>
<div className='container'>
<div className='row'>
<div className='s12' />
</div>
<div className='row'>
<div className='s8 offset-s2 center-align'>
<div className='card green accent-4 z-depth-2'
style={{...styles, opacity: this.props.opacity, transform: 'scale(' + this.props.scale + ')'}}>
<div className='card-content white-text'>
<span className='card-title'>Title</span>
</div>
<div className='card-action'>
<a onClick={this.props.hide}>HIDE</a>
</div>
</div>
</div>
</div>
</div>
</div>
)
}
}
这是我的MainContainer.js文件(容器)
import React from 'react'
import { Main } from '../components/Main'
export class MainContainer extends React.Component {
constructor (props) {
super(props)
this.state = {
opacity: 1,
scale: 1
}
this.handleHide = this.handleHide.bind(this)
this.handleScale = this.handleScale.bind(this)
}
handleHide () {
this.setState({
opacity: 0
})
alert('Goodbye world')
}
handleScale () {
this.setState({
scale: this.state.scale > 1 ? 1 : 1.2
})
}
render () {
let hide = this.handleHide
return (
<Main hide={hide} />
)
}
}
答案 0 :(得分:2)
如下所示在MainContainer.js中修改您的代码...
<Main hide={hide} {...this.state} />
