可自定义设置以下属性：
- 消息的标题（title），默认'温馨提示'
- 自动关闭的延时时长（duration），单位ms，默认4500ms
- 消息从顶部弹出时，距离顶部的位置（top），单位像素px，默认24px
- 消息从底部弹出时，距离底部的位置（bottom），单位像素px，默认24px
- 弹出位置（placement），可选：左上topLeft，右上topRight（默认），左下bottomLeft，右下bottomRight
调用时可选以下五个方法对应五种不同样式：
- notification.value.open(info) // 默认使用
- notification.value.info(info) // info调用
- notification.value.success(info) // success调用
- notification.value.error(info) // error调用
- notification.value.warn(info) // warn调用
五种样式效果如下图：
open()调用：
info()调用：
success()调用：
error()调用：
warn()调用：
①创建通知提醒框组件Notification.vue：
<script setup lang="ts">
import { ref, computed, watch } from 'vue'
// 以下两个方法是用 requestAnimationFrame 实现的等效 setTimeout() 和 clearTimeout()
import { rafTimeout, cancelRaf } from '../index'
const props = defineProps({

type: String,
default: '温馨提示'
},
duration: { // 自动关闭的延时时长,单位ms，默认4500ms；设置null时，不自动关闭
type: Number,
default: 4500
},
top: { // 消息从顶部弹出时，距离顶部的位置，单位像素px
type: Number,
default: 24
},
bottom: { // 消息从底部弹出时，距离底部的位置，单位像素
type: Number,
default: 24
},
placement: { // 消息弹出位置，可选topLeft,topRight,bottomLeft,bottomRight
type: String,
default: 'topRight'
}
})
enum ColorStyle { // 颜色主题对象
info = '#1890FF',
success = '#52c41a',
error = '#f5222d',
warn = '#faad14'
}
interface Notification {
notification: string,

}
const resetTimer = ref()
const hideIndex = ref<number[]>([])
const hideTimers = ref<any[]>([])
const notificationData = ref<Notification[]>([])
const clear = computed(() => {
// 所有提示是否已经全部变为false
return hideIndex.value.length === notificationData.value.length
})
watch(clear, (to, from) => { // 所有提示都消失后重置
if (!from && to) {
resetTimer.value = rafTimeout(() => {
hideIndex.value.splice(0)
notificationData.value.splice(0)
}, 300)
}
})
function onEnter (index: number) {
cancelRaf(hideTimers.value[index])
hideTimers.value[index] = null
}
function onLeave (index: number) {
if (props.duration) {
hideTimers.value[index] = rafTimeout(() => {
onClose(index)
}, props.duration)
}
}
function show () {
cancelRaf(resetTimer.value)
hideTimers.value.push(null)
const index = notificationData.value.length - 1
if (props.duration) {
hideTimers.value[index] = rafTimeout(() => {
onClose(index)
}, props.duration)
}
}
function open (notification: string) {
notificationData.value.push({
notification,
mode: 'open'
})
show()
}
function info (notification: string) {

show()
}
function success (notification: string) {

}
function error (notification: string) {

show()
}
function warn (notification: string) {

})
show()
}
defineExpose({

})
const emit = defineEmits(['close'])
function onClose (index: number) {
hideIndex.value.push(index)
emit('close')
}
