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 | slottype: String,default: '提示'},content: { // 内容 string | slottype: String,default: ''},width: { // 宽度，默认640type: Number,default: 640},height: { // 高度，默认480type: 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：falsetype: 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')
}
</script>

const footer = ref(false)

function showFixDialog (info: string) {center.value = falsecontent.value = infovisible.value = true
}
function onClose () { // 关闭回调visible.value = false
