将多个CSS动画组合成一个整体动画 [英] combining multiple css animations into one overall animation

问题描述

我有一组动画，我排队一个接一个创建一个更大的整体动画。为了简单起见，我创建了一个简单的小提琴来演示我的意思，但它是我想要实现的一个简化版本（底部代码）...

I have a set of animations that I queue up one after the other to create a bigger overall animation. For the sake of simplicity, I've created a simple fiddle to demo what I mean, but it's a simplified version of what I'm trying to achieve (code on bottom)...

http://jsfiddle.net/UnsungHero97/qgvrs/5/

我想做的是将所有这些组合成一个动画而不是几个。目前，我添加了一个类来触发动画的不同阶段，但我想要做的是添加一个类只有一次来启动动画，然后就可以了。

What I want to do is combine all of these into one animation instead of several. Currently, I add a class to trigger the different stages of the animation, but what I would like to do is add a class only once to start the animation, and then it'll just go.

我不知道如何将动画组合成一个，因为他们工作在不同的元素。

I don't see how to combine the animations into one since they work on different elements. I'm still fairly new to CSS3 animations, so is it possible to do this?

任何想法？

HTML

<div class="outside">
    <div class="inside"></div>
</div>

CSS

.outside {
    border: 1px solid magenta;
    height: 100px;
    width: 100px;
    position: relative;
}

.inside {
    border: 1px solid skyblue;
    height: 60px;
    width: 60px;
    margin-top: -31px;
    margin-left: -31px;
    position: absolute;
    top: 50%;
    left: 50%;
}

@-webkit-keyframes scale-in {
  0% {
    -webkit-transform: scale(0);
  }
  100% {
    -webkit-transform: scale(1);
  }
}

@-webkit-keyframes bounce {
  0% {
    -webkit-transform: scale(1);
  }
  25% {
    -webkit-transform: scale(.8);
  }
  50% {
    -webkit-transform: scale(1);
  }
  75% {
    -webkit-transform: scale(.9);
  }
  100% {
    -webkit-transform: scale(1);
  }
}

@-webkit-keyframes rotate {
    0% {
    -webkit-transform: rotate(0deg);
    }
    100% { 
    -webkit-transform: rotate(360deg);
    }
}

.bounce {
  -webkit-animation-duration: 500ms;
    -webkit-animation-name: bounce;
}

.animate {
    -webkit-animation-delay: 0s;
    -webkit-animation-fill-mode: forwards;
    -webkit-animation-timing-function: ease;
    -webkit-transform: translateZ(0);
}

.click {
    border: 1px solid skyblue;
    -webkit-animation-duration: 1000ms;
    -webkit-animation-name: rotate;
}

.click .inside {
    border: 1px solid magenta;
    -webkit-animation-duration: 1000ms;
    -webkit-animation-name: rotate;
}

.clicked {
    border: 1px solid magenta;
}

.clicked .inside {
    border: 1px solid skyblue;
    -webkit-animation-duration: 750ms;
    -webkit-animation-name: scale-in;
}

JS

$(document).ready(function() {
    $(document).click(function() {
        var jqElement = $('.outside');

        jqElement
          .off()
          .addClass('animate')
          .addClass('bounce');

        jqElement.on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(event) {

          event.stopPropagation();

          jqElement
            .removeClass('bounce')
            .removeClass('animate')
            .off()
            .addClass('animate')
            .addClass('click');

          jqElement.on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(event) {

            event.stopPropagation();

            jqElement
              .removeClass('click')
              .removeClass('animate')
              .off()
              .addClass('clicked');

            setTimeout(function() {
              jqElement.removeClass('clicked');
            }, 500);
          });
        });
    });
});

推荐答案

一个动画一个元素是如何作为动画更改单个元素的样式。

One animation one element is how it works as the animations change the styles of a single element. You can however apply delays to the animations to achieve what you want, allowing you to move pretty much everything out of JS.

此示例合并了您的 .outside 一个 .inside 动画，通过基本上附加一个逗号到规则，你的JS现在只是添加类如下 -webkit-animation-name：button-bounce，rotate，skyblue;

This example merges your .outside an .inside animations, by basically appending them with a comma to the rule and you JS now just adds the class like this -webkit-animation-name: button-bounce, rotate, skyblue;

jsFiddle

.outside.animate {
    -webkit-animation-delay: 0s, .5s, .5s;
    -webkit-animation-duration: 500ms, 1000ms, 1000ms;
    -webkit-animation-name: button-bounce, rotate, skyblue;
}

.animate {
    -webkit-animation-fill-mode: forwards;
    -webkit-animation-timing-function: ease;
    -webkit-transform: translateZ(0);
}

.outside.animate .inside {
    -webkit-animation-delay: .5s, .5s, 1.5s;
    -webkit-animation-duration: 1000ms, 1000ms, 750ms;
    -webkit-animation-name: rotate, magenta, scale-in;
}

新动画

New animations

@-webkit-keyframes magenta {
    0% { border: 1px solid magenta; }
    99.99% { border: 1px solid magenta; }
    100% { border: 1px solid skyblue; }
}
@-webkit-keyframes skyblue {
    0% { border: 1px solid skyblue; }
    99.99% { border: 1px solid skyblue; }
    100% { border: 1px solid magenta; }
}

JavaScript

JavaScript

$(document).ready(function() {
    $(document).click(function() {
        var count = 0;
        var jqElement = $('.outside');
        if (!jqElement.hasClass('animate')) {
            jqElement.addClass('animate');
            jqElement.on('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd', function(event) {
                count++;
                if (count >= 6) {
                    jqElement.off('animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd');
                    jqElement.removeClass('animate');
                }
            });
        }
    });
});
