CSS / HTML Modal-使用Esc键/单击外面关闭 [英] CSS/HTML Modal- Using the Escape key/Click outside to close

问题描述

我有以下模态工作，

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

在我的网站上。这正是我想要的易用性和功能。我唯一的问题是如何使模态关闭时，用户A）点击模态窗口外，或B）点击退出键。

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.

任何建议？

    <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;
}

推荐答案

小javascript。检查代码有一些注释。

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);

请注意，关闭模态在技术上只能使用CSS / HTML，但是对于处理Escape键按下您将需要Javascript。

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