带有图像描述的模态图像
我在这里找到了有关制作多个模态图像的代码。 然而，当我打开模式时，我似乎找不到添加描述文本的最佳方法。我一直在关注这篇文章的第二个到最后一个答案的代码: Several Modal Images on page 这对我帮助很大，但我需要描述文本而不是标题文本。 如果有人愿意帮助我解决这个问题，我将不胜感激。 预先感谢您!
代码:
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {
opacity: 0.7;
}
.modal {
display: none;
/* Hidden by default */
position: fixed;
/* Stay in place */
z-index: 1;
/* Sit on top */
padding-top: 100px;
/* Location of the box */
left: 0;
top: 0;
width: 100%;
/* Full width */
height: 100%;
/* Full height */
overflow: auto;
/* Enable scroll if needed */
background-color: rgb(0, 0, 0);
/* Fallback color */
background-color: rgba(0, 0, 0, 0.9);
/* Black w/ opacity */
}
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}
#text {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}
.modal-content,
#text {
animation-name: zoom;
animation-duration: 0.6s;
}
@keyframes zoom {
from {
transform: scale(0)
}
to {
transform: scale(1)
}
}
.close {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
}
.close:hover,
.close:focus {

最佳答案
您需要用 div 包裹 img + text，因此点击 wrapped div 后，然后通过 .innerHTML< 选择内部内容 属性并将模态 img 更改为 div。
只需对 js 代码 modalImg.src = this.src 进行小修改即可 modalImg.innerHTML = this.innerHTML;
类似下面的片段。
我希望下面的代码片段对您有很大帮助。
var modal = document.getElementById('myModal');
// to all images -- note I'm using a class!
var images = document.getElementsByClassName('myImg');
// the image in the modal
var modalImg = document.getElementById("img01");
// and the caption in the modal
var captionText = document.getElementsByClassName("text");
// Go through all of the images with our custom class
for (var i = 0; i < images.length; i++) {
var img = images[i];
// and attach our click listener for this image.
img.onclick = function(evt) {
modal.style.display = "block";
// modalImg.src = this.src;
modalImg.innerHTML = this.innerHTML;
captionText.innerHTML = this.alt;
}
}
var span = document.getElementsByClassName("close")[0];
span.onclick = function() {
modal.style.display = "none";
}*,*:before, *:after{box-sizing: border-box;}
