HTML

Question

我应该在 html 或 javascript 或其他代码中编写一些代码，以通过单击图像打开弹出窗口 window。我已经看过 window.open() 方法，但这不是我要找的。准确地说，我想像 Twitter 那样打开一个图像弹出窗口：遮盖背景并在屏幕中间显示放大的图像。

有什么建议吗？

Answer 1

您可以使用 Bootstrap，否则，制作一个 DIV，位置 absolute/fixed 并居中。单击获取图像的 URL 并将其放入 img 标签中的新 DIV 中。最后在新的DIV中添加一个fadeIn/Out作为效果

Answer 2

您可以使用灯箱来完成。

这里有一个简单的例子link:

Answer 3

您可以使用 lightbox.

使用起来真的很简单。在 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 */
    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 (image) */
.modal-content {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
}

/* Caption of Modal Image */
#caption {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
    text-align: center;
    color: #ccc;
    padding: 10px 0;
    height: 150px;
}

/* Add Animation */
.modal-content, #caption {    
    -webkit-animation-name: zoom;
    -webkit-animation-duration: 0.6s;
    animation-name: zoom;
    animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
    from {-webkit-transform:scale(0)} 
    to {-webkit-transform:scale(1)}
}

@keyframes zoom {
    from {transform:scale(0)} 
    to {transform:scale(1)}
}

/* The Close Button */
.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;
}

/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
    .modal-content {
        width: 100%;
    }
}

一种非常简单的方法，可以在单击“单击此处”文本时弹出图像。

<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>
