Using esc to close an image

How can I implement the use of "esc" key, or other accessibility features to close a pop-up image with this script?

document.querySelectorAll('.card img').forEach(image => {
  image.onclick = () => {
    document.querySelector('.popup-image').style.display = 'block';
    document.querySelector('.popup-image img').src = image.getAttribute('src');
  }
})

document.querySelector('.popup-image span').onclick = () => {
  document.querySelector('.popup-image').style.display = 'none';
}

document.querySelectorAll('.card img').forEach(image => {
  image.onclick = () => {
    document.querySelector('.popup-image').style.display = 'block';
    document.querySelector('.popup-image img').src = image.getAttribute('src');
  }
})

document.querySelector('.popup-image span').onclick = () => {
  document.querySelector('.popup-image').style.display = 'none';
}

It just display an image fixed.

Very basically this: https://codepen.io/jochemm/pen/ExRRWMO?editors=1011 replace the dialog.close() with whatever you need to do to hide your image but you've gotta listen for the keypress and then react to it

Document.addeventlistener("keydown"), function (e) {
    If (e.keyCode == 27){
        /// Your action here
    }
}

Document.addeventlistener("keydown"), function (e) {
    If (e.keyCode == 27){
        /// Your action here
    }
}

I'm such a slow typer lol

event.keyCode is deprecated, you shouldn't use it anymore 🙂 you should use event.code, and then compare against "Escape"

Oh good to know 👍 Don't know why my VS code isn't showing that it's deprecated

I had to look it up on MDN to be sure

Thanks for the heads-up!

Doesn't e.key just say the name of the key e.g. ESC

Jochem•2y ago

"Escape", but yes

I was pretty close to this, but I guess I failed. Thanks to you, and everyone 😊

I usually use e.key.tolowercase then check what I want

I was working with dialogs. Made this function to close it when clicking, thinking it works outside of the content, but it closes anywhere.

modal.forEach((modal) => {
  modal.addEventListener("click", (e) => {
    if (e.target.class !== "modal-content") {
      modal.close();
    }
  });
});

modal.forEach((modal) => {
  modal.addEventListener("click", (e) => {
    if (e.target.class !== "modal-content") {
      modal.close();
    }
  });
});

Any clue what might be wrong? The CSS is simply:

dialog>.modal
  div>.modal-content
    p>"some content"

dialog>.modal
  div>.modal-content
    p>"some content"
