React Edit Multiples Input Components Example

The input elements often have a property called name, age, mobile, address, and pincode. We can access these properties from the event object that we receive from an event handler.

Explore to Understand  - React Lifecycle Components

Write a generalized change handler:
    handleChange = (eventpropertyName=> {
        const detail = this.state.detail;
        detail[propertyName] = event.target.value;
        this.setState({ detail: detail });
    }

As an Example,
import React, { Component } from 'react'

export default class UserDetail extends Component {
    constructor(props) {
        super(props);
        this.state = this.props.location.state;
    }

    handleChange = (eventpropertyName=> {
        const detail = this.state.detail;
        detail[propertyName] = event.target.value;
        this.setState({ detail: detail });
    }

    render() {
        return (
            <>
                <div>
                    <input type="text" onChange={this.handleChange.bind(this'name')} value={this.state.detail.name} />
                    <input type="text" onChange={this.handleChange.bind(this'age')} value={this.state.detail.age} />
                    <input type="text" onChange={this.handleChange.bind(this'mobile')} value={this.state.detail.mobile} />
                    <input type="text" onChange={this.handleChange.bind(this'address')} value={this.state.detail.address} />
                    <input type="text" onChange={this.handleChange.bind(this'pincode')} value={this.state.detail.pincode} />
                    <button type="button" className="btn btn-primary" onClick={this.updateDetail}>Update</button>
                </div>
            </>
        )
    }
}
