vue-router进阶-3-过渡动效

template:
<transition>
  <router-view></router-view>
</transition>

单个路由的过渡

const Foo = {
  template: `
    <transition name="slide">
      <div class="foo">...</div>
    </transition>
  `
}

const Bar = {
  template: `
    <transition name="fade">
      <div class="bar">...</div>
    </transition>
  `
}

基于路由的动态过渡

<!-- 使用动态的 transition name -->
<transition :name="transitionName">
  <router-view></router-view>
</transition>

// 接着在父组件内
// watch $route 决定使用哪种过渡
watch: {
  '$route' (to, from) {
    const toDepth = to.path.split('/').length
    const fromDepth = from.path.split('/').length
    this.transitionName = toDepth < fromDepth ? 'slide-right' : 'slide-left'
  }
}
