javascript - css和脚本库调整
问题描述
我有一个包含缩略图的简单图片库,当您单击图片时,图片会在弹出窗口中展开。
我的问题是我只能使此功能与一张图像一起使用。
我明白身体在呼唤
<div id="myModal" class="modal">
<img class="modal-content" id="img01
脚本正在调用
var modalImg = document.getElementById("img01");
我只是无法弄清楚我需要对这些元素做什么才能使弹出功能适用于所有缩略图?任何帮助都会很棒!
代码:
// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it inside the modal - use its "alt" text as a
caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function() {
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
.thumbnails img {
height: 80px;
border: 4px solid #fff;
padding: 1px;
margin: 0 10px 10px 0;
}
.thumbnails img:hover {
border: 4px solid #00ccff;
cursor: pointer;
}
.thumbnails h2 {
color: white;
}
.thumbnails h3 {
color: white;
}
#myImg {
border-radius: 0px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {
opacity: 0.7;
}
