Refreshing Counter using React

In React, the counter is nothing but a number with two buttons. One is to increment its value, and the other is to decrement its value. But, in this case, we have one different button called the 'reset button' instead of the decrement button, which is used to refresh the count. 


onClick() event handler enables us to call a function and trigger an action when we click an element, such as a button, in our React application. Event names should be in camelCase, so the onClick event is written as onClick in a React application. In this case, the onClick event handler triggers the counter to start the counter. It includes all our actions inside a function and calls that single function from the onClick event handler in React. The main purpose of the onClick event handler is to allow the programmer to execute a JavaScript function when an element gets clicked by the user. This event is also used for validating forms or applications, warning messages, and many more. Restore a form element's default values using the method reset(). Counter-resetting is a CSS property that will reset a CSS counter to a given value. It will create a new or reversed counter with a certain name on the specified element in React, and the normal counters have an initial default value of 0. 


Here is an example of how you can create a refresh counter using React:

Code

In this solution we're using React library.

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.

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


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for 'how to implement refresh counter using react' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in Visual Studio Code 1.73.1.
  2. The solution is tested on node v18.12.1 and npm v8.19.2.
  3. React version-18.2.0.


Using this solution, we are able to implement refreshing counter using React with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement refreshing counter using React.
