javascript - onClick使用jquery显示当前div

Question

我正在这里处理图像库，我希望 onClick 图像当前图像显示在 .gallery-container 中，该图像工作正常，但问题是当前图像标题未显示，因为我在 jquery 中定位图像源，我尝试添加标题也却无法实现。谁能指出我正确的方向。

$(document).ready(function() {
  $('.gallery-column img').on('click', function() {
    var expandImg = document.getElementById("expandedImg");
    expandImg.src = this.src;
    expandImg.parentElement.style.display = "block";
  });
});

* {
  box-sizing: border-box;
}

.gallery-wrap {
  width: 50%;
  height: 1066px;
  margin: 0 auto;
  display: flex;
}

.gallery-row {
  width: 52%;
  max-height: 497px;
}

.gallery-column {
  position: relative;
  padding: 10px;
}

.img-caption {
  position: absolute;
  bottom: 10%;
}

.gallery-column img {
  width: 100%;
  opacity: 0.8;
  cursor: pointer;
}

.gallery-column img:hover {
  opacity: 1;
}

.gallery-container {
  position: relative;
  width: 90%;
  height: 500px;
}

#expandedImg {
  width: 100%;
  height: 100%;
}

只需添加以下代码即可实现图像点击功能。

var _caption = $(this).next("div").html();
$("#expandedImgCaption").html(_caption);

expandedImgCaption 是展开图像的标题 ID

代码片段:

$(document).ready(function() {
  $('.gallery-column img').on('click', function() {
    var expandImg = document.getElementById("expandedImg");
    expandImg.src = this.src;
    expandImg.parentElement.style.display = "block";
    var _caption = $(this).next("div").html();
    $("#expandedImgCaption").html(_caption);
  });
});

* {
  box-sizing: border-box;
}

.gallery-wrap {
  width: 50%;
  height: 1066px;
  margin: 0 auto;
  display: flex;
}

.gallery-row {
  width: 52%;
  max-height: 497px;
}

.gallery-column {
  position: relative;
  padding: 10px;
}

.img-caption {
  position: absolute;
  bottom: 10%;
}

.gallery-column img {
  width: 100%;
  opacity: 0.8;
  cursor: pointer;
}

.gallery-column img:hover {
  opacity: 1;
}

.gallery-container {
  position: relative;
  width: 90%;
  height: 500px;
}

#expandedImg {
  width: 100%;
  height: 100%;
}
