Vue 的过渡系统提供了非常多简单的方法来设置进入、离开和列表的动效，那么对于数据元素本身的动效呢？比如：
- 数字和运算
- 颜色的显示
- SVG 节点的位置
- 元素的大小和其他的 property
这些数据要么本身就以数值形式存储，要么可以转换为数值。有了这些数值后，我们就可以结合 Vue 的响应性和组件系统，使用第三方库来实现切换元素的过渡状态。
状态动画与侦听器
通过侦听器我们能监听到任何数值 property 的更新。可能听起来很抽象，所以让我们先来看看一个使用 GreenSock 的例子：
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js"></script>
<div id="animated-number-demo">
<input v-model.number="number" type="number" step="20" />
<p>{{ animatedNumber }}</p>
</div>const Demo = {
data() {
return {
number: 0,
tweenedNumber: 0
}
},
computed: {
animatedNumber() {
return this.tweenedNumber.toFixed(0)
}
},
watch: {
number(newValue) {
gsap.to(this.$data, { duration: 0.5, tweenedNumber: newValue })
}
}
}
Vue.createApp(Demo).mount('#animated-number-demo')看看完整的DEMO：

动态状态过渡
就像 Vue 的过渡组件一样，用于支撑状态过渡的数据也可以实时更新，这对于原型设计十分有用！只需要对变量做一些修改，即使是一个简单的 SVG 多边形也可实现很多难以想象的效果。

</html>把过渡放到组件里
管理太多的状态过渡会迅速增加组件实例的复杂度，幸好很多的动画可以提取到专用的子组件中。我们把之前的整数动画示例改写一下：
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js"></script>
<div id="app">
<input v-model.number="firstNumber" type="number" step="20" /> +
<input v-model.number="secondNumber" type="number" step="20" /> = {{ result }}
<p>
<animated-integer :value="firstNumber"></animated-integer> +
<animated-integer :value="secondNumber"></animated-integer> =
<animated-integer :value="result"></animated-integer>
</p>
</div>JS代码：
const app = Vue.createApp({
data() {
return {
firstNumber: 20,
secondNumber: 40
}
},
computed: {
result() {
return this.firstNumber + this.secondNumber
}
}
})
app.component('animated-integer', {
template: '<span>{{ fullValue }}</span>',
props: {
value: {
type: Number,
required: true
}
},
data() {
return {
tweeningValue: 0
}
},
computed: {
fullValue() {
return Math.floor(this.tweeningValue)
}
},
methods: {
tween(newValue, oldValue) {
gsap.to(this.$data, {
duration: 0.5,
tweeningValue: newValue,
ease: 'sine'
})
}
},
watch: {
value(newValue, oldValue) {
this.tween(newValue, oldValue)
}
},
mounted() {
this.tween(this.value, 0)
}
})
app.mount('#app')我们看看完整的DEMO：

</html>现在我们可以使这些子组件与多个状态相组合。这让人感到兴奋——我们能在组件中结合使用这一节讲到各种过渡策略和 Vue 内建的过渡系统。总之，对于完成各种过渡动效几乎没有阻碍。
你可以看到我们如何使用它进行数据可视化、物理效果、角色动画和交互，一切都没有限制。
赋予设计以生命
动画效果可以栩栩如生。不幸的是，设计师创建图标、logo 和吉祥物的时候，他们交付的通常都是图片或静态的 SVG。所以，虽然 GitHub 的章鱼猫、Twitter 的小鸟以及其它许多 logo 类似于生灵，它们看上去实际上并不是活着的。
Vue 可以帮到你。因为 SVG 的本质是数据，我们只需要准备好这些生物兴奋、思考或警戒的样例。然后 Vue 就可以辅助完成这几种状态之间的过渡动画，来制作你的欢迎页面、加载指示和更加带有情感的通知提示。
Sarah Drasner 展示了下面这个根据时间和交互变化发生状态改变的 demo：
