HTML-JS如何通过单击打开图像弹出窗口?

6
我需要写一些HTML、Javascript或其他相关的代码,通过单击图像来打开弹出窗口。我已经看过了window.open()方法,但这不是我想要的。我想要的是像Twitter那样打开一个图片弹出窗口:遮盖背景并在屏幕中央显示放大的图像。你有什么建议吗?

请包含您的代码。 - Jason D

您可以使用灯箱

它非常简单易用。在您的HTML文件中包含脚本标签和CSS样式表,然后只需使用:

<a class="example-image-link" href="images/image-1.jpg" data-lightbox="example-1"><img class="example-image" src="images/thumb-1.jpg" alt="Girl looking out people on beach"></a>

// 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";
}
#myImg {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */

点击“点击这里”的文字时,弹出图片的一种非常简单的方法。

<a href="" onclick="window.open('img.png','targetWindow', 'toolbar=no, location=no, status=no, menubar=no, scrollbars=yes, resizable=yes, width=1090px, height=550px, top=25px left=120px'); return false;">click here</a>

你可以使用Bootstrap,否则可以创建一个绝对/固定位置的DIV并居中。点击时获取图像的URL,并将其放入新的DIV中的img标签中。最后为新的DIV添加fadeIn/Out效果。
