Question

我有一个html / css / js模式在fadeIn和slideIn前提下工作，但我似乎无法让它在关闭时做反向...它只是让人很难跳到“不在那里”。

我在JS中的关闭功能只是采用modal.style.display =“none”但是有没有办法访问我在css中添加的@keyframes以顺利反转？

HTML：

<h2>Bottom Modal</h2>

<button id="button">Click Me</button>

<div id="modal">

<div id="modal-content">
    <div id="modal-header">
        <span id="close">&times</span>
        <h2>modal header</h2>
    </div>

    <div id="modal-body">
        <p>Some text in the modal body</p>
        <p>Some other text in the modal body</p>
    </div>

    <div id="modal-footer">
        <h2>modal footer</h2>
    </div>

</div><!--modal-content-->
</div><!--modal div-->

CSS：

#modal
{
position: fixed;
z-index:1;
left:0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color:rgba(0,0,0,0.4);
-webkit-animation-name: fadeIn;
-webkit-animation-duration: 0.4s;
animation-name: fadeIn;
animation-duration: 0.4s;
display: none;
}

#modal-content
{
position: fixed;
bottom: 0;
backgroun-color: #fefefe;
width: 100%;
-webkit-animation-name: slideIn;
-webkit-animation-duration: 0.4s;
animation-name: slideIn;
animation-duration: 0.4s;

}

#close
{
color: white;
float: right;
font-size: 28px;
font-weight: bold;
}

#close:hover, #close:focus
{
color: #000;
text-decoration: none;
cursor: pointer;
}

#modal-header
{
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

#modal-footer
{
padding: 2px 16px;
background-color: #5cb85c;
color: white;
}

#modal-body
{
padding: 2px 16px;
background-color: white;
}

 @-webkit-keyframes slideIn
 {
 from {bottom: -300px; opacity: 0}
 to {bottom: 0; opacity: 1}
 }

@keyframes slideIn
 {
 from {bottom: -300px; opacity: 0}
 to {bottom: 0; opacity: 1}
 }

@-webkit-keyframes fadeIn
{
from {opacity: 0}
to {opacity: 1}
}

@keyframes fadeIn
{
from {opacity: 0}
to {opacity: 1}
}

JS：

var modal = document.getElementById("modal");

var button = document.getElementById("button");

var close = document.getElementById("close");

button.onclick = function()
{
modal.style.display="block";
};

close.onclick = function()
{
modal.style.display="none";
};

window.onclick = function(event)
{
if(event.target == modal)
{
modal.style.display="none";
}
};

根据发布的问题：

无法访问@keyframes规则 - 没有巨大的黑客（将css作为文本并使用正则表达式解析规则，甚至在100％的情况下都无法做到）< / p>
访问关键帧规则无法满足您的要求
设置display:none
但是，您可以通过Javascript库动态生成，激活，停止和再次播放@keyframe动画，例如jQuery.keyframes

通过JS访问@keyframes
