problem description

    this.state = {
        data: null,
        visible: false
    };
    
    const open = (data) => {
        this.setState({
            data,
            visible: true
        });
    }
    
    return (
        <div>content</div>
    );
}

prompt Unhandled Rejection (TypeError): _ this.setState is not a function

when executing open ()

tried

const that = this;
that.setState({})

hold the same mistake and ask the boss for an answer.

this is the stateless component. You do not inherit the react method, so there is no lifecycle, no render, no state,setState method. Search the stateless component and you will find out

if you write this as a stateless component, there is no lifecycle, and of course there is no react.component method. You need to change it to

class Name extends React.Component(){
 constructor() {
    super()
    this.state = {
      
    }
  }
   render (){}


}
