我使用以下代码设法slideDown
下拉菜单。但这显然只有在单击下拉切换类时才有效。
如何整合Bootstrap的功能,当点击下拉列表中的li
或点击外部时,下拉菜单消失。
$('.dropdown-toggle').click(function() {
$(this).next('.dropdown-menu').slideToggle(500);
});
<div class="dropdown">
<div class="dropdown-toggle" data-toggle="dropdown">Click Me</div>
<ul class="dropdown-menu optfulwidth ulreligion">
<li>one</li>
<li>two</li>
<li>three</li>
<li>four</li>
</ul>
</div>

您不需要额外的CSS来打开和关闭下拉列表。
<div class="dropdown clearfix">
<div class="dropdown-toggle" data-toggle="dropdown"><a>Click Me</a></div>
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu" >
<li><a href="#">One</a></li>
<li><a href="#">Two</a></li>
<li><a href="#">three</a></li>
</ul>
</div>
这是一个bootply
如果您希望它向下滑动,请添加以下
// ADD SLIDEDOWN ANIMATION TO DROPDOWN //
$('.dropdown').on('show.bs.dropdown', function(e){
$(this).find('.dropdown-menu').first().stop(true, true).slideDown();
});
// ADD SLIDEUP ANIMATION TO DROPDOWN //
$('.dropdown').on('hide.bs.dropdown', function(e){
$(this).find('.dropdown-menu').first().stop(true, true).slideUp();
});

如果你想要更详细的东西,你可以把令人敬畏的Animate.css(一个CSS动画的跨浏览器库),一些jquery,当然还有Twitter Boostrap。
在标题中:
<head>
...
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous" />
</head>
在您要创建下拉列表的正文中:
<div class="dropdown" data-animation="slideInDown,slideOutUp,600">
<button type="button" class="btn btn-primary" data-toggle="dropdown">Click to toggle animated dropdown <i class="caret"></i></button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
注意标记中的数据动画属性,你必须提供3个参数,动画中,动画外和持续时间。
如果你喜欢other animations,你可以玩。
在您的页脚中(或在您渲染脚本的任何位置):
<script src="js/jquery-2.1.1.min.js"></script>

<script type="text/javascript">
$(function () {
var $in, $out, $duration;
$('.dropdown')
.on('shown.bs.dropdown',
function (e) {

let $animations = [];
const $animation = $(this).data('animation');
$animations = $animation.split(',');
$in = 'animated ' + $animations[0];
$out = 'animated ' + $animations[1];
$duration = '';
if (!$animations[2]) {
$duration = 500;
} else {
$duration = $animations[2];
}
$(this).find('.dropdown-menu').removeClass($out);
$(this).find('.dropdown-menu').addClass($in);
}
});
$('.dropdown')
.on('hide.bs.dropdown',
function (e) {
if ($(this).attr('data-animation')) {
e.preventDefault();
const $this = $(this);
const $targetControl = $this.find('.dropdown-menu');
$targetControl.addClass($out);
setTimeout(function () {
$this.removeClass('open');
},
$duration);
}
});
})
</script>
希望这有帮助!
需要完整样本吗?
$(function () {
var $in, $out, $duration;
$('.dropdown')
.on('shown.bs.dropdown',
function (e) {
if ($(this).attr('data-animation')) {
let $animations = [];
const $animation = $(this).data('animation');
$animations = $animation.split(',');
$in = 'animated ' + $animations[0];
$out = 'animated ' + $animations[1];
$duration = '';
if (!$animations[2]) {
$duration = 500;
} else {
$duration = $animations[2];
}
$(this).find('.dropdown-menu').removeClass($out);
$(this).find('.dropdown-menu').addClass($in);
}
});
$('.dropdown')
.on('hide.bs.dropdown',
function (e) {
if ($(this).attr('data-animation')) {
e.preventDefault();
const $this = $(this);
const $targetControl = $this.find('.dropdown-menu');
$targetControl.addClass($out);
setTimeout(function () {
$this.removeClass('open');
},
$duration);
}
});
})
