vue3 - 自定义弹框组件

写了一个弹框组件

<template>
  <transition name="modal-fade">
    <div v-if="showFlag" class="myModal">
      <div class="content">
        <div class="topBox">
          <div class="leftTitle">
            <span>{{ title }}</span>
          </div>
          <div class="rightClose" @click="cancelModal"><CloseOutlined /></div>
        </div>
        <slot name="content"></slot>
      </div>
    </div>
  </transition>
</template>

<script setup lang="ts">
import { ref, toRefs } from 'vue'

const props = defineProps({
  title: {
    type: String,
    default: '',
  },
})

const { title } = toRefs(props)

// 是否开启弹框
let showFlag = ref(false)

// 开启
const showModal = () => {
  showFlag.value = true
}

// 关闭
const cancelModal = () => {
  showFlag.value = false
}

defineExpose({
  showModal,
  cancelModal,
})
</script>

<style lang="less" scoped>
// 这个动画是，打开弹框时，有一个缓慢打开的效果
@keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

// 打开弹框时给它一个上下抖动的效果
@keyframes shake {
  0% { transform: translateY(0); }
  25% { transform: translateY(-10px); }
  50% { transform: translateY(0); }
  75% { transform: translateY(10px); }
  100% { transform: translateY(0); }
}

.myModal {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.4);
  z-index: 100;

  animation: fadeIn 0.5s;
  // animation: fadeIn 0.5s, shake 0.5s;

  .content {
    position: absolute;
    left: 50%;
    top: 30%;
    transform: translate(-50%, -50%);
    background: #ffffff;
    width: 500px;
    padding: 10px;

    .topBox {
      display: flex;
      height: 30px;
      border-bottom: 1px solid #f0f0f0;
      padding: 0 10px 0 0;
      margin-bottom: 20px;
      cursor: pointer;

      .leftTitle {
        flex: 1;
        text-align: left;
        color: rgba(0, 0, 0, 0.8);
        font-weight: 600;
        font-size: 16px;
      }

      .rightClose {
        flex: 1;
        text-align: right;
      }
    }
  }
}

// start - 效果为：关闭时，有一个缓慢消失的效果
.modal-fade-enter-active, .modal-fade-leave-active {
  transition: opacity 0.5s;
}
.modal-fade-enter, .modal-fade-leave-to {
  opacity: 0;
}
// end - 效果为：关闭时，有一个缓慢消失的效果
</style>
