我正在尝试使用reactjs创建一个应用程序。以下是我的主要app.js中提供的代码:
class App extends Component {
return (
<div>
<ExampleTable
header={() => <TopBar/>}
/>
<AddExampleModal/>
<ChartModal/>
<CompatibilityAlert/>
</div>
)
}
}
从其他js文件加载了Top Bat,AddExampleModal,ChartModal和CompatibilityAlert。
Chartmodal包含:
class ChartModal extends Component{
constructor(props){
super(props)
}
render(){
return(
<Modal
onOk={()=>console.log('ok')}
onCancel={()=>console.log('cancel')}
visible={true}
okText={'ok'}
cancelText={'cancel'}
confirmLoading={false}
title="Intent distribution chart"
>
<h1>HOWDY</h1>
<TreeMap
data={chartData}
width={400}
valueUnit={'count'}
/>
</Modal>
)
}
}
顶栏包含:
class TopBar extends Component {
render{
return (
<Button
style={styles.button}
type='primary'
// onClick={() => changechartshow()}
>
Show Graph
</Button>
)
}
}
关键是在应用程序文件中,我想使用顶部栏中的按钮来切换chartmodal的可见性。
最佳答案
应用程式
class App extends Component {
constructor() {
this.state = {
isVisible: true
}
}
toggleVisibility = () => this.setState({isVisible: !this.state.isVisible})
render () {
const {isVisible} = this.state;
return (
<div>
<ExampleTable
header={() => <TopBar toggleVisibility =
{this.toggleVisibility.bind(this)}
/>}
<AddExampleModal/>
<ChartModal isVisible={isVisible}/>
<CompatibilityAlert/>
</div>
);
}
}
顶栏
class TopBar extends Component {
render{
return (
<Button
style={styles.button}
type='primary'
onClick={() => this.props.toggleVisibility()}
>
Show Graph
</Button>
)
}
}
ChartModal-将状态传递给可见属性
class ChartModal extends Component{
constructor(props){
super(props)
}
render(){
return(
<Modal
onOk={()=>console.log('ok')}
onCancel={()=>console.log('cancel')}
visible={this.props.isVisible}
okText={'ok'}
cancelText={'cancel'}
confirmLoading={false}
title="Intent distribution chart"
>
<h1>HOWDY</h1>
<TreeMap
data={chartData}
width={400}
valueUnit={'count'}
/>
</Modal>
)
}
}
