vue3 数据大屏 项目开发中，需要弹窗组件，这里我们整理弹窗组件，并通过gsap补间动画给弹窗添加入场动画以及离场动画。

弹窗效果

弹窗动画

展开动画：从中间缓慢向上下两边展开；
收缩动画：从上下两边向中间收缩隐藏。

使用组件

组件可传值宽高控制大小。标题宽度随内部文字的多少而变化。

<template>
  <div class="popBody">
    <el-button @click="getShow" type="primary">弹窗</el-button>
    <pop ref="pop" width="300px" height="500px">
      dsfsdfsd
    </pop>
  </div>
</template>

<script>

import pop from './pop.vue'

export default {
  data() {
    return {}
  },
  components: {pop},
  computed: {},
  methods: {
    getShow() {
      this.$refs.pop.getShow()
    }
  },
}
</script>

<style lang="scss" scoped>
.popBody {
  position: relative;
  width: 100%;
  height: 100%;
}
</style>

组件抽离

弹窗的边框样式可以抽离出来，用作大屏的小边框样式：vue3 数据可视化大屏蓝色边框-四角加梯形标题样式
