CSS/HTML 模态 - 使用 Escape 键/单击外部关闭

问题描述

我有以下模态工作，

http://jsfiddle.net/kumarmuthaliar/GG9Sa/1/

在我的网站上.就易用性和功能而言，这正是我想要的.我遇到的唯一问题是当用户 A) 在模态窗口外单击或 B) 按 Escape 键时如何关闭模态.

有什么建议吗?

 <a href="#openModal">打开模态</a><div id="openModal" class="modalDialog">
<a href="#close" title="关闭" class="close">X</a><h2>模态框</h2><p>这是一个示例模态框，可以使用 CSS3 的强大功能创建.</p><p>您可以在这里做很多事情，例如在您的网站加载时显示弹出广告，或者为用户创建登录/注册表单.</p></div></div>.modalDialog {位置:固定；字体系列:Arial、Helvetica、sans-serif；顶部:0；右:0；底部:0；左:0；背景:rgba(0, 0, 0, 0.8);z 指数:99999；不透明度:0；-webkit-transition:不透明度 400ms 缓入；-moz-transition:不透明度 400ms 缓入；过渡:不透明度 400ms 缓入；指针事件:无；}.modalDialog:目标{不透明度:1；指针事件:自动；}.modalDialog >分区 {宽度:400px；位置:相对；保证金:10% 自动；填充:5px 20px 13px 20px；边框半径:10px；背景:#fff;背景:-moz-线性渐变(#fff，#999)；背景:-webkit-linear-gradient(#fff, #999);背景:-o-线性梯度(#fff，#999)；}.关闭 {背景:#606061；颜色:#FFFFFF；行高:25px；位置:绝对；右:-12px；文本对齐:居中；顶部:-10px；宽度:24px；文字装饰:无；字体粗细:粗体；-webkit-border-radius:12px；-moz-边界半径:12px；边框半径:12px；-moz-box-shadow: 1px 1px 3px #000;-webkit-box-shadow: 1px 1px 3px #000;盒子阴影:1px 1px 3px #000;}.close:悬停{背景:#00d9ff；}

为此，您需要一点 JavaScript.用一些注释检查代码.

函数 modalClose() {if (location.hash == '#openModal') {location.hash = '';}}//处理 ESC 键(键码 27)document.addEventListener('keyup', function(e) {如果(e.keyCode == 27){模态关闭()；}});var modal = document.querySelector('#openModal');//处理模态容器的点击modal.addEventListener('click', modalClose, false);//如果在模态内容正文中发生单击，则防止事件冒泡modal.children[0].addEventListener('click', function(e) {e.stopPropagation();}， 错误的);

请注意，关闭模式在技术上仅适用于 CSS/HTML，但是要处理 Escape 按键，您将需要 Javascript.

I have the following modal working,

http://jsfiddle.net/kumarmuthaliar/GG9Sa/1/

on my site. It's exactly what I want in terms of ease of use, and function. The only issue I have is how to make the modal close when the user either A) Clicks outside the modal window, or B) Hits the Escape key.

Any suggestions?

    <a href="#openModal">Open Modal</a>

    <div id="openModal" class="modalDialog">
        <div>   <a href="#close" title="Close" class="close">X</a>

                <h2>Modal Box</h2>

            <p>This is a sample modal box that can be created using the powers of CSS3.</p>
            <p>You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.</p>
        </div>
    </div>

.modalDialog {
    position: fixed;
    font-family: Arial, Helvetica, sans-serif;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: rgba(0, 0, 0, 0.8);
    z-index: 99999;
    opacity:0;
    -webkit-transition: opacity 400ms ease-in;
    -moz-transition: opacity 400ms ease-in;
    transition: opacity 400ms ease-in;
    pointer-events: none;
}
.modalDialog:target {
    opacity:1;
    pointer-events: auto;
}
.modalDialog > div {
    width: 400px;
    position: relative;
    margin: 10% auto;
    padding: 5px 20px 13px 20px;
    border-radius: 10px;
    background: #fff;
    background: -moz-linear-gradient(#fff, #999);
    background: -webkit-linear-gradient(#fff, #999);
    background: -o-linear-gradient(#fff, #999);
}
.close {
    background: #606061;
    color: #FFFFFF;
    line-height: 25px;
    position: absolute;
    right: -12px;
    text-align: center;
    top: -10px;
    width: 24px;
    text-decoration: none;
    font-weight: bold;
    -webkit-border-radius: 12px;
    -moz-border-radius: 12px;
    border-radius: 12px;
    -moz-box-shadow: 1px 1px 3px #000;
    -webkit-box-shadow: 1px 1px 3px #000;
    box-shadow: 1px 1px 3px #000;
}
.close:hover {
    background: #00d9ff;
}

For this you will need a little javascript. Check the code with some comments.

function modalClose() {
    if (location.hash == '#openModal') {
        location.hash = '';
    }
}

// Handle ESC key (key code 27)
document.addEventListener('keyup', function(e) {
    if (e.keyCode == 27) {
        modalClose();
    }
});

var modal = document.querySelector('#openModal');

// Handle click on the modal container
modal.addEventListener('click', modalClose, false);

// Prevent event bubbling if click occurred within modal content body
modal.children[0].addEventListener('click', function(e) {
    e.stopPropagation();
}, false);

Note, that closing modal is technically possible with CSS/HTML only, however for handling Escape key press you will need Javascript.
