JS:
// 获取弹窗 var modal = document.getElementById('myModal'); // 获取图片插入到弹窗 - 使用 "alt" 属性作为文本部分的内容 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; } // 获取 <span> 元素,设置关闭按钮 var span = document.getElementsByClassName("close")[0]; // 当点击 (x), 关闭弹窗 span.onclick = function() { modal.style.display = "none"; }
