我想在卡片标题中有一个下拉按钮,点击后会显示如下选项的下拉列表:

我知道这可以通过将卡的溢出设置为overflow: visible !important
来完成。 但这会导致点击时卡片显示的动画效果不佳。您可以在此处查看动画:
我希望卡片揭示的显示动画通常像这样动画:https://jsfiddle.net/506ubrxh/2/
所以我希望在点击列表图标时动态更改卡片的溢出属性,以便在用户点击列表按钮并更改回{{overflow: visible !important
时更改为overflow: hidden
1}}当用户关闭下拉列表时。我编写了jQuery来执行此操作,但代码似乎不起作用。下面是我的html,css和jquery代码。
HTML代码:
<div class="card">
<div class="card-image waves-effect waves-block waves-light">
<img class="activator" src="http://materializecss.com/images/office.jpg">
</div>
<div class="card-content">
<span class="card-title activator grey-text text-darken-4">Card Title</span>
<i class="material-icons right dropdown-button" data-activates="dropdown1">list</i>
</div>
<div class="card-reveal">
<span class="card-title grey-text text-darken-4">Card Title<i class="material-icons right listExpand">close</i></span>
<p>Here is some more information about this product that is only revealed once clicked on.</p>
</div>
<ul id='dropdown1' class='dropdown-content'>
<li><a href="#!">one</a></li>
<li><a href="#!">two</a></li>
<li class="divider"></li>
<li><a href="#!">three</a></li>
</ul>
</div>
css代码:
.card {
width: 60%;
overflow: visible !important;
}
jQuery代码:
$(document).ready(function(){
$('.listExpand').click(function(){
if($(this).hasClass('active'))
$('.card').css("overflow", "visible !important");
});
});

如果有人可以提供帮助,那真是太棒了!

虽然Twitter Bootstrap和Zurb Foundation等CSS框架为其组件提供了API,但遗憾的是,MaterialiseCSS框架主要缺少公共API来为组件设置自定义事件处理程序,尤其是对于下拉列表。
因此,我们必须手动设置处理程序,直到它们提供API - Example Here :
.card--visible-overflow {
overflow: visible !important;
}
$(document)
// remove the visibility class from all cards
// if the target of the click event is not a dropdown button
.on('click', function(e) {
if (! $(e.target).hasClass('dropdown-button')) {
$('.card').removeClass('card--visible-overflow');
}
})
// add the visibility class to the closest card
// by clicking on each dropdown button inside the card
.on('click', '.card .dropdown-button', function() {
var $card = $(this).closest('.card'),
openedClass = 'card--visible-overflow',
dropDownIsOpened = $card.hasClass(openedClass);
if (! dropDownIsOpened) {
$card.addClass(openedClass);
}
});
