To pass multiple props in a single event handler in ReactJS we can create a function to handle the event that accepts multiple props or calls multiple methods. It is a normal task while creating a react project to perform multiple operations for some events.

Prerequisites

To pass/call the multiple props methods in a single event handler in ReactJS there are two ways to make it work.

Method 1: Defining specific methods

We can make a separate method for the event and call all the props methods in that method. 

Syntax

const seperateMethod = () => {
props.method1()
props.method2()
}

Method 2: Using anonymous methods

We can create an anonymous function and call all the props methods inside the anonymous method.

Syntax

<Component onClick={() => {
props.method1();
props.method2()
}}>
</Component>

Steps to create React Application

Step 1: Create a React application using the following command:

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command:

cd foldername

Project Structure:

Example: Passing multiple props in a single event handler with both methods

Javascript

import React from 'react';
export default class App extends React.Component {
 
    sayHi = () => {
        alert("Hi from GFG");
    }
    sayHello = () => {
        alert("Hello from GFG");
    }
 
    render() {
        return (
            <div style={{ marginLeft: 50 }}>
                <Child1 m1={this.sayHi}
                    m2={this.sayHello} >
                </Child1>
                <br></br>
                <Child2 m1={this.sayHi}
                    m2={this.sayHello}>
                </Child2>
            </div>
        )
    }
}
 
// Method 1
class Child1 extends React.Component {
 
    seperatemethod = () => {
        this.props.m1();
        this.props.m2();
    }
 
    render() {
        return (
            <div>
                <button onClick={this.seperatemethod}>
                    Hello Hi from GFG
                </button>
            </div>
        )
    }
}
 
// Method 2
class Child2 extends React.Component {
 
    render() {
        return (
            <div>
                <button onClick={() => {
                    this.props.m1();
                    this.props.m2();
                }}
                >Hello hi from GFG</button>
            </div>
        )
    }
}
