Vue 3.0 状态过渡 实例详解

vue 2022-05-07 17:05:56小码哥的IT人生shichen

Vue 的过渡系统提供了非常多简单的方法设置进入、离开和列表的动效。那么对于数据元素本身的动效呢，比如：

  1. 数字和运算
  2. 颜色的显示
  3. SVG 节点的位置
  4. 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 的数值更新。可能听起来很抽象，所以让我们先来看看使用 GreenSock 一个例子：

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js" rel="external nofollow"  rel="external nofollow" ></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')

更新数字时，更改将在输入下方设置动画。

#动态状态过渡

就像 Vue 的过渡组件一样，数据背后状态过渡会实时更新，这对于原型设计十分有用。当你修改一些变量，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。

#把过渡放到组件里

管理太多的状态过渡会很快的增加组件实例复杂性，幸好很多的动画可以提取到专用的子组件。我们来将之前的示例改写一下：

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js" rel="external nofollow"  rel="external nofollow" ></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>
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，天空是极限。

#赋予设计以生命

只要一个动画，就可以带来生命。不幸的是，当设计师创建图标、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，我们只需要这些动物兴奋、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、以及更加带有情感的提示。

Sarah Drasner 展示了下面这个 demo，这个 demo 结合了时间和交互相关的状态改变：
