Show/Hide buttons are helpful when you want to provide the user control over what information is displayed on the screen. For instance, a menu, a form, or a block of text may be toggled between visible and hidden using a show/hide button. Show/hide buttons may also be used to keep the interface simple and uncluttered when they are not required while revealing extra information or options when needed. 


To construct a show/hide button with React, no extra packages are required. The component's state may be managed using the built-in useState hook, and when the button is pressed, the state can be toggled using the onClick event handler. 

  • useState: React's useState hook allows you to add state to functional components. You can handle state in your components without changing them into class components thanks to this. To manage numerous bits of state, you can employ the useState hook several times in a single component. 
  • onClick: When an element is clicked in React, the onClick function is run as an event handler. When an element is clicked, it is used to start an action or run some code. 


For more information about show/hide button in React, refer to the code given below.

In this solution we use the React library.

class Home extends React.PureComponent {
 constructor(props) {
    super(props);
    this.state={
        showImage:false
    }
  }
  change = () =>{
      this.setState({
          showImage:!this.state.showImage
      })
  }
  render() {
    return(
      <>
      <Option change={this.change}/>
      {
          this.state.showImage?
              <img src="abc.jpg" width="100%"/>
            :
            <div>Welcome!!!</div>
      }
      </>
    )
  }
}

class Option extends React.Component{
  constructor(props) {
    super(props);
    this.state = {
      isOpen: false
    };
  }
  toggleOpen = () => this.setState({ isOpen: !this.state.isOpen });
  render(){
    const menuClass = `dropdown-menu${this.state.isOpen ? " show" : ""}`;
    return(
      <>
      <button onClick={()=>this.props.change()} className="btn btn-secondary dropdown-toggle" id="dropdownMenuButton"  aria-haspopup="true" type="button" data-toggle="dropdown"> Dropdown</button>
       <div aria-labelledby="dropdownMenuButton">
          <a className="dropdown-item">
            Show Data
          </a>
       </div>
      </>
    )
  }
}

1.Created onchange function in home function and passed as prop to option
2.On click of button i called onchange function in Option component.
3.I am maintaining flag in Home component for conditional rendering.
4.For now i have onchange function on button click,you can have it anywhere and call it.

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 (line no 1 to 26) it in App.js and create a option.js file paste the option code(line no 27 to 48) in that file(remove the earlier code from App.js).
  6. Import React library and import option from option file.
  7. Add the last line of the code as (export default Home) to App.js and (export default Option) to option.js file.
  8. Add image source in the App.js.file
  9. Open the terminal from IDE.
  10. 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 'Show/Hide button in Reactjs' 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 VS Code 1.73.1 version.
  2. The solution is tested on Nodejs 16.14.2 version.
  3. react 18.2.0 version


Using this solution, we are able to Create Show/Hide button in Reactjs 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 Create Show/Hide button in Reactjs.
