Vue 实现多级弹窗的方法

多级弹窗通常指弹窗内嵌套弹窗的场景，以下是几种常见的实现方式：

组件嵌套方式

创建独立的弹窗组件，通过v-if或v-show控制显示层级：

<template>
  <div>
    <button @click="showFirstModal = true">打开一级弹窗</button>

    <!-- 一级弹窗 -->
    <FirstModal v-if="showFirstModal" @close="showFirstModal = false">
      <button @click="showSecondModal = true">打开二级弹窗</button>

      <!-- 二级弹窗 -->
      <SecondModal v-if="showSecondModal" @close="showSecondModal = false"/>
    </FirstModal>
  </div>
</template>

<script>
export default {
  data() {
    return {
      showFirstModal: false,
      showSecondModal: false
    }
  }
}
</script>

动态组件方式

使用Vue的<component>实现动态弹窗层级管理：

<template>
  <div>
    <button @click="openModal('first')">打开弹窗</button>

    <component 
      :is="currentModal"
      v-for="(modal, index) in modalStack"
      :key="index"
      @close="closeModal"
      @open-child="openChildModal"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      modalStack: [],
      components: {
        first: FirstModal,
        second: SecondModal
      }
    }
  },
  computed: {
    currentModal() {
      return this.modalStack[this.modalStack.length - 1]
    }
  },
  methods: {
    openModal(type) {
      this.modalStack.push(this.components[type])
    },
    closeModal() {
      this.modalStack.pop()
    },
    openChildModal(type) {
      this.openModal(type)
    }
  }
}
</script>

状态管理方式（Vuex/Pinia）

适合复杂场景下的弹窗状态管理：

// store/modals.js (Pinia示例)
export const useModalStore = defineStore('modals', {
  state: () => ({
    stack: []
  }),
  actions: {
    open(component, props) {
      this.stack.push({ component, props })
    },
    close() {
      this.stack.pop()
    }
  }
})

组件中使用：

<template>
  <div>
    <button @click="openFirstModal">打开弹窗</button>

    <component
      v-for="(modal, index) in modalStack"
      :key="index"
      :is="modal.component"
      v-bind="modal.props"
      @close="closeModal"
    />
  </div>
</template>

<script setup>
import { useModalStore } from './store/modals'
const modalStore = useModalStore()
const modalStack = computed(() => modalStore.stack)

const openFirstModal = () => {
  modalStore.open(FirstModal, { title: '一级弹窗' })
}
const closeModal = () => {
  modalStore.close()
}
</script>

遮罩层处理技巧

多级弹窗需要处理z-index和遮罩层：

vue实现多级弹窗

.modal-mask {
  position: fixed;
  z-index: 1000;
  background: rgba(0,0,0,0.5);
}

.modal-content {
  z-index: 1001;
}

/* 二级弹窗 */
.modal-mask .modal-mask {
  z-index: 2000;
}

.modal-mask .modal-content {
  z-index: 2001;
}
