Hello to all, welcome back to my blog. Today in this blog post, I am going to tell you, Reactjs Show Flash Message on Button Click.

For react js new comers, please check the below link:
React js Basic Tutorials

Friends now I proceed onwards and here is the working code snippet for Reactjs Show Flash Message on Button Click please use this carefully to avoid the mistakes:

1. Firstly friends we need fresh reactjs setup and for that we need to run below commands into our terminal and also w should have latest node version installed on our system:

Guys you can skip this first step if you already have reactjs fresh setup:

npx create-react-app reactmessage

cd reactmessage

npm start // run the projec

2. Now friends, we need to run below commands into our reactjs project to install react flash message modules:

npm i react-flash-message

npm start

3. Now friends we need to add below code into our src/App.js file to get final output on web browser:

import React from 'react';
import './App.css';

import FlashMessage from 'react-flash-message'

class App extends React.Component
{
  //Specify the state object in the constructor method to set the variable with value for flash message:
  constructor(props) {
    super(props);
    this.state = {showMessage: false};
    
  }

//Button click function
showmessage()
  {
    //Make div show containing flash message
    this.setState({ showMessage: true });

    //Make div hide containing flash message
    setTimeout(
      () => this.setState({ showMessage: false }),
      5000
    );
  }
  render()
  {
    return (
      <div>
        
            <button onClick={e => {this.showmessage()}}>Show Flash Message</button>
       
              { this.state.showMessage &&  
                <div className="flashdiv">
                 <FlashMessage duration={5000}>
                  <strong>Hello Therichpost!</strong>
                 </FlashMessage>
               </div>
               }
       
      </div>  
) } }
 export default App;

4. In the end, now friends we need to add below code into our src/App.css file to style flash message:

.flashdiv
{
  position: fixed!important; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 2%;
  bottom: 3%;
  overflow: auto; /* Enable scroll if needed */
  background-color: rgb(0,0,0); /* Fallback color */
  background-color: rgba(0,0,0,0.5); /* Black w/ opacity */
  border-radius: 5px;;
  padding:10px;
  color: #ffffff;
}

Now we are done friends. If you have any kind of query or suggestion or any requirement then feel free to comment below.
