Left side of image disappears

Question

After clicking on the play image, the left side of it disappears, and is not visible.

How do I get the left side of the play image to stay visible and not disappear?

I don't understand why this is happening.

How is this issue resolved?

That is everything about the problem I am having.

Answer 1

'Click' event is working only on the left side image. Because, here querySelector() is used. It will return an Element object representing the first element in the document that matches the specified set of CSS selectors, or null is returned if there are no matches.

Instead you can use querySelectorAll() like this

using ES6:

  const cover = document.querySelectorAll('.jacketa');
  cover.forEach(el => el.addEventListener('click', coverClickHandler));

using For Loop:

  const cover = document.querySelectorAll('.jacketa');
    for (var i = 0; i < cover.length; i++) {
      cover[i].addEventListener('click', coverClickHandler);
  }

Now both sides of the image will trigger the event.
