Nextjs render a new div on click

Question

I have an image and I want to create a new div (on click) with a larger version of the same image.

I tried four methods:

1. Render div on click

function zoom_img (event) {
    console.log(event.target);
    console.log(event.target['data-loaded-src'])
    const src = event.target['data-loaded-src']
    
    return (
      <div className='w-screen h-screen fixed flex justify-center items-center'>
        <div className='w-9/12 h-5/6 bg-slate-200 opacity-50'>
          <Image src={src} fill={true} />
        </div>
      </div>
    )
  }

...

<Image src={'/gafas.png'} width={150} height={150} alt='Gafas 1' onClick={zoom_img}/>

2. Custom component

function Glasses ({src, height, width, alt}) {
    function enlrg() {
      console.log(src);
      return (
        <div className='w-screen h-screen fixed flex justify-center items-center'>
          <div className='w-9/12 h-5/6 bg-slate-200 opacity-50'>
            <Image src={src} fill={true} />
          </div>
        </div>
      )
    }
    return (
      <Image src={src} width={width} height={height} alt={alt} onClick={enlrg} />
    )
  }


...

<Glasses src={'/gafas.png'} width={150} height={150} alt='Gafas 1' />

3. Existing div onClick delete hidden class

function Glasses2 ({src, height, width, alt}) {
    function enlrg() {
      console.log(src);
      let x = document.getElementById('temp');
      x.classList.remove('hidden');
      x.classList.add('flex');
    }
    return (
      <Image src={src} width={width} height={height} alt={alt} onClick={enlrg} />
    )
  }


...

<Glasses2 src={'/gafas.png'} width={150} height={150} alt='Gafas 1' />
<div id='temp' className='w-screen h-screen fixed hidden justify-center items-center'>
  <div className='w-9/12 h-5/6 bg-slate-200 opacity-50'>
    <Image src={'/gafas.png'} fill={true} />
  </div>
</div>

4. This does work, but I lost nextjs image optimization

function zoom_img (event) {
    console.log(event.target);
    console.log(event.target['data-loaded-src'])
    const src = event.target['data-loaded-src']
    const new_cont = document.createElement('div');
    const new_div = document.createElement('div');
    const main = document.getElementById('main');
    new_cont.classList.add('w-screen', 'h-screen', 'fixed', 'flex', 'justify-center', 'items-center');
    new_div.classList.add('w-9/12', 'h-5/6', 'bg-slate-200', 'opacity-50');
    // add img tag here
    new_cont.appendChild(new_div);
    main.appendChild(new_cont);
  }


...

<Image src={'/gafas.png'} width={150} height={150} alt='Gafas 1' onClick={zoom_img} />

In every method I can see the logs in the console, but only in method 4 I can see the new div.

Is method 4 the only correct way? I'd prefer to use an image component if possible. What do you think?

Answer 1

Thank you so much @Atena Dadkhah. Your answer is very valid.

In the project, there is not one but a bunch of images, so the final code looks like this:

function enlarge(e) {
    setLrg(true);
    let img = document.getElementById('largerImage'),
        src = e.target['data-loaded-src'];
    img['src'] = src;
  }

Then a bunch of images like this:

Then the hidden div:

It still lacks the behavior of closing the div, but this should be easy to add.

again. Thanks:)

Answer 2

You could try something like this:

Set hook:

[zoomImage, setZoomImage] = useState(false)

 setZoomImage(true)}/>

// zoomed image


   

In this code you are essentially telling Next.JS to change the variable zoomImage to true whenever the user clicks on the image, so the larger image that is hidden by default will Has a display block. (I guess you are using tailwindcss)
