vue router 配合transition 切换动画

  把<router-view>嵌套在<transition>里,路由变化的时候,vue会为包裹页面的div增加动画样式,我们要做的就是监听路由变化、定义这些动画样式,以规定页面到底怎么切换。具体样式名通过transition的name属性绑定。下面是在移动端模拟一般app界面的前进后退动画:

<template>
  <div id="app">
    <transition :name="direction" >
      <router-view class="appView"></router-view>
    </transition>
  </div>
</template>

<script>
export default {
  name: "App",
  data: () => ({
    direction: "slide-right"
  }),
  watch: {
    $route(to, from) {
      const toDepth = to.path.split("/").length;
      const fromDepth = from.path.split("/").length;
      if (to.path == "/") {
        this.direction = "slide-right";
      } else if (from.path == "/") {
        this.direction = "slide-left";
      }else{
        this.direction = toDepth < fromDepth ? "slide-right" : "slide-left";
      }
    }
  }
};
</script>

<style>
.appView {
  position: absolute;
  width:100%;
  transition: transform 0.3s ease-out;
}
.slide-left-enter{
  transform: translate(100%, 0);
}
.slide-left-leave-active{
  transform: translate(-50%, 0);
}
.slide-right-enter {
  transform: translate(-50%, 0);
}
.slide-right-leave-active{
  transform: translate(100%, 0);
}
</style>

  具体动画方式都能在$router的watch里面去定义。

  建议增加router的scrollBehavior,定义来回切换的页面位置。

  吐槽下在移动端没办法配合手势滑动来实现良好的router回退。
