import React from ‘react‘
class RegisterStepTwo extends React.Component{
state = {
visible: true
}
changeVisible(){
this.setState({visible: !this.state.visible});
}
refCb(instance){

}
render(){
return(
<div>
<button type="button" onClick={this.changeVisible.bind(this)}>{this.state.visible ? ‘卸载‘ : ‘挂载‘}ConfirmPass
</button>
{
this.state.visible ?
<div ref={this.refCb}/>: null

export default RegisterStepTwo;
使用场景：
import React from ‘react‘
class NameForm extends React.Component {
constructor(props) {
super(props);
this.state = {value: ‘‘};
}
render() {
return (
<div>
<input type="text" ref={el=>this.input =el} placeholder="演出/艺人/场馆"/>
<button onClick={this.Searchtitle.bind(this)}>获取</button>
</div>
);
}
Searchtitle(){ console.log(this.input.value) //实时的获取输入框中的值 }
}
}
export default NameForm;
