Refreshing Counter using React

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we're going to see how to implement refreshing counter using React with simple steps. Using onClick to increment the count in the counter. The counter value initially set as 0, on every onClick the value will increment by +1. After that we can refresh the values we incremented using resetCounter. You can increment as much as required and we'll reset it to start again from initially 0. To implement this task, use the ready-made code snippet below by just copying the code and paste it in your IDE with React library. Explore more top trending libraries and code snippets on kandi.

class TestJs extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            count: 0
        }
        this.onClick = this.onClick.bind(this);
        this.resetCounter = this.resetCounter.bind(this);
    }

    onClick(e) {
        this.setState({
            count: this.state.count + 1
        });
    }

    resetCounter(){
        this.setState({count : 0});
    }

    render() {
        return (
            <div>
                Counter value is {this.state.count}
                <br/>
                <button onClick={this.onClick}> Increase counter</button>
                <br/>
                <button onClick={this.resetCounter}> Reset counter</button>
            </div>
        );
    }
}

export default TestJs

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in app.js file(remove the earlier code from app.js).
Import React in app.js file.
Open the terminal from IDE.
npm start to run the file.
