①创建对话框组件Dialog.vue：
<script setup lang="ts">
import Button from '../button'
import { ref, computed, useSlots, watch, nextTick } from 'vue'
import type { CSSProperties } from 'vue'
interface Props {
title?: string // 标题 string | slot
content?: string // 内容 string | slot
width?: number // 宽度，单位p
height?: number | string // 高度，单位px，默认auto，自适应内容高度
cancelText?: string // 取消按钮文字
okText?: string // 确定按钮文字
okType?: 'primary' | 'danger' // 确定按钮类型
footer?: boolean // 是否显示底部按钮 boolean | slot
center?: boolean // 水平垂直居中：true 固定高度水平居中：false
top?: number // 固定高度水平居中时，距顶部高度，仅当 center: false 时生效
switchFullscreen?: boolean // 是否允许切换全屏，允许后右上角会出现一个按钮
loading?: boolean // 确定按钮 loading
bodyStyle?: CSSProperties // 对话框 body 样式
show?: boolean // 对话框是否可见
}
const props = withDefaults(defineProps<Props>(), {
title: '提示',
content: '',
width: 540,
height: 'auto',
cancelText: '取消',
okText: '确定',
okType: 'primary',
footer: true,
center: true,

switchFullscreen: false,

bodyStyle: () => ({}),
show: false
})
const fullScreen = ref(false)
const dialogHeight = computed(() => {
if (typeof props.height === 'number') {
return props.height + 'px'
} else {
return props.height
}
})
const dialogRef = ref() // DOM 引用
const slots = useSlots()
const showFooter = computed(() => {
const footerSlots = slots.footer?.()
return footerSlots
})
watch(
() => props.show,
(to) => {
if (to) {
nextTick(() => {
dialogRef.value.focus()
})
// 重置全屏显示
fullScreen.value = false
}
}
)
const emits = defineEmits(['update:show', 'cancel', 'ok'])
function onBlur() {
emits('update:show', false)
emits('cancel')
}
function onFullScreen() {
fullScreen.value = !fullScreen.value
}
function onClose() {
emits('update:show', false)
emits('cancel')
}
function onCancel() {
emits('update:show', false)
emits('cancel')
