您有多個(gè)具有相同 id 的元素 - 將其更改為一個(gè)類。let如果你想分配事件，你的代碼也需要在循環(huán)中使用。終于不是mouseout了mouseleave。


這行得通。


var imgContainer = document.getElementsByClassName('text__container');

var imgText = document.getElementsByClassName('img__text');


for (let i = 0; i < imgText.length; i++) {

  imgContainer[i].addEventListener('mouseover', function() {

    imgText[i].style.opacity = "1";

    imgText[i].style.transition = "0.8s ease-in";

  });


  imgContainer[i].addEventListener('mouseout', function(){

    imgText[i].style.opacity = "0";

    imgText[i].style.transition = "0.8s ease-out";

  });

}

.gallery__container {

    margin-top: 5%;

    display: flex;

    flex-direction: row;

    flex-wrap: wrap;

    justify-content: space-between;

    div {

      background-color: #000;

      width: 49%;

      margin: 0 0 2% 0;

      height: 665px;

      display: grid;

      

      img {

        grid-column: 1;

        grid-row: 1;

        z-index: 1;

        align-content: center;

        transition: 0.8s ease-out;

        opacity: 1;

        &:hover {

          transition: 0.8s ease-in;

          cursor: pointer;

          opacity: 0.5;

        }

      }

      .text__container {

        border: 1px solid red;

        text-align: center;
