【问题描述】:
我有一个 html/css/js 模态在 fadeIn 和 slideIn 前提下工作,但我似乎无法让它在关闭时做相反的事情......它只是很难跳到“不存在”。
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我的 css 中添加的@keyframes 以进行平滑的反转?
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">×</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";
}
};
【问题讨论】:
-
设置
element.style.display='none'后无法为任何东西设置动画。 -
如果您不介意使用它,我认为您可以使用 jQuery 轻松实现它。除此之外所有的动画都是
Opacity: 0 to 1
