javascript-如何让 JS 显示不同的图像

我用这个脚本来显示带有图像的模式,但我想这样做,弹出的模式将显示按下的特定图像。
问题是JS只响应第一个img,但当我将第二个img添加到脚本中时,它只是不起作用。。。有没有简单的方法让JS为每个img工作,或者我需要为每个img编写整个脚本?
var modal = document.getElementById("myModal");
var img = document.getElementById("myImg");
var modalImg = document.getElementById("img1"); // second img (img1)
var modalImg = document.getElementById("img2"); // second img (img2)
img.onclick = function() {
modal.style.display = "block";
modalImg.src = this.src;
}
var span = document.getElementsByClassName("close")[0];
span.onclick = function() {
modal.style.display = "none";
}
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {
opacity: 0.7;
}
.modal {
display: none;
position: fixed;
z-index: 1;
padding-top: 100px;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgb(0, 0, 0);
background-color: rgba(0, 0, 0, 0.9);
}
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}
.modal-content,
{
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 {
color: #bbb;
text-decoration: none;
cursor: pointer;
}
@media only screen and (max-width: 700px) {
.modal-content {
width: 100%;
}
}
<div>
