React: OnClick On Button Not Working

For the past hour, I have been trying to get this to work. onClick on any of the buttons is not working at all… What am I doing wrong? const React = require('react'); class Ques

Solution 1:

You need to bind the function to the component like so:

class Questionnaire extends React.Component {
    constructor (props) {
        super(props);
        this.state = { selectedSection: 0 };

        this.selectSection = this.selectSection.bind(this)
    }

Keep everything else the same

Solution 2:

Try This

    const React = require('react');

    class Questionnaire extends React.Component {
    constructor (props) {
        super(props);
        this.state = { selectedSection: 0 };
    }

    selectSection = function(e){
    console.log(e);
  }

    render () {
        return (
            <div>
                <div className='btn-group mr-2' role='group'>
                    <button className='btn btn-primary' onClick={this.selectSection}>A</button>
                    <button className='btn btn-secondary' onClick={this.selectSection}>B</button>
                    <button className='btn btn-secondary' onClick={this.selectSection}>C</button>
                    <button className='btn btn-secondary' onClick={this.selectSection}>D</button>
              </div>
            </div>
        );
    }
    }

Solution 3:

You need to bind the method to the class. Add this line to the constructor:

this.selectSection = this.selectSection.bind(this);
