CSS动画:轻轻过渡删除类

Zkk*_*Zkk 7 css jquery animation css3

在此代码中,模式通过轻微转换(CSS3)调用.当我点击"Clode Modal"课程时.is-active被删除.但是,它会立即被删除.我想做相反的效果.

打开模态时,它从左到右显示.当我关闭模态时,我希望他做相反的效果.他在哪里(中)到左边.

我怎样才能做到这一点？

$('.section-modal .profile, .section-modal .overlay .modal .title').click(function(){
  $('.overlay').toggleClass('is-active');
});

这是实现这一目标的一种方法。

$('.section-modal .profile, .section-modal .overlay .modal .title').click(function() {
var $overlay = $('.overlay');

if ($overlay.hasClass('is-active')) {
	$overlay.addClass('hidden').on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(){
		$overlay.removeClass('is-active hidden');
	})
} else {

主要区别在于，当添加了隐藏类时，我将反向动画应用于当前活动类：

.section-modal .overlay.is-active.hidden {
    -webkit-animation: overlayAnim 2s ease-in-out reverse;
    animation: overlayAnim 2s ease-in-out reverse;
}
.section-modal .overlay.is-active.hidden .modal {
    -webkit-animation: modalAnim 2s ease-in-out reverse;
    animation: modalAnim 2s ease-in-out reverse;
}

在这里，我检查是否存在活动类，如果存在，则立即添加一个隐藏类，并等待动画完成，然后再删除它们：

if ($overlay.hasClass('is-active')) {
    $overlay.addClass('hidden').on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(){
        $overlay.removeClass('is-active hidden');
    })
} else {
    $overlay.addClass('is-active');
}

我认为这会成功。
