Vue3对话框（Dialog）

Vue2对话框（Dialog）

可自定义设置以下属性：

标题（title），类型：string | slot，默认 '提示'
内容（content），类型：string | slot，默认 ''
宽度（width），类型：number，默认 640px
高度（height），类型：number，默认 480px
是否允许切换全屏，允许后右上角会出现一个按钮（switchFullscreen），类型：boolean，默认 false
取消按钮文字（cancelText），类型：string，默认 '取消'
确认按钮文字（okText），类型：string，默认 '确认'
是否显示底部按钮（footer），类型：boolean，默认 false
是否水平垂直居中（center），类型：boolean，默认 true，（false时是固定高度水平居中）
固定高度水平居中时，距顶部高度（top），类型：number，默认 100px
加载中（loading），类型：boolean，默认 false
对话框是否可见（visible），类型：boolean，默认 false

效果如下图：（整体样式模仿ant-design-vue Modal，同时阴影覆盖浏览器窗口）

①创建对话框组件Dialog.vue：

<script setup lang="ts">
import { ref, computed, watch } from 'vue'
const props = defineProps({
    title: { // 标题 string | slot
      type: String,
      default: '提示'
    },
    content: { // 内容 string | slot
      type: String,
      default: ''
    },
    width: { // 宽度，默认640
      type: Number,
      default: 640
    },
    height: { // 高度，默认480
      type: Number,
      default: 480
    },
    switchFullscreen: { // 是否允许切换全屏，允许后右上角会出现一个按钮
      type: Boolean,
      default: false
    },
    cancelText: { // 取消按钮文字
      type: String,
      default: '取消'
    },
    okText: { // 确认按钮文字
      type: String,
      default: '确定'
    },
    footer: { // 是否显示底部按钮，默认不显示
      type: Boolean,
      default: false
    },
    center: { // 水平垂直居中：true  固定高度水平居中：false
      type: Boolean,
      default: true
    },
    top: { // 固定高度水平居中时，距顶部高度
      type: Number,
      default: 100
    },
    loading: { // 加载中
      type: Boolean,
      default: false
    },
    visible: { // 对话框是否可见
      type: Boolean,
      default: false
    }
  })

const fullScreen = ref(false)
const dialogWidth = computed(() => {
  if (fullScreen.value) {
      return '100%'
    } else {
      return props.width + 'px'
    }
  })
const dialogHeight = computed(() => {
    if (fullScreen.value) {
      return '100vh'
    } else {
      return props.height + 'px'
    }
  })
watch(
  () => props.visible, (to) => {
    if (!to) { // 重置全屏显示
      fullScreen.value = false
    }
})
const emits = defineEmits(['close', 'cancel', 'ok'])
function onBlur () {
  if (!props.loading) {
    emits('close')
  }
}
function onFullScreen () {
  fullScreen.value = !fullScreen.value
}
function onClose () {
  emits('close')
}
function onCancel () {
  emits('cancel')
}
function onConfirm () {
  emits('ok')
}
