Vue3全局提示（Message）

Vue2全局提示（Message）

可自定义设置以下属性：

• 自动关闭的延时（duration），类型：number，单位ms，默认 3000ms

• 消息距离顶部的位置（top），类型：number，单位px，默认 30px

调用一次只展示一个提示，调用多次则依次展示多个，按照调用先后顺序依次自动关闭。

效果如下图：在线预览

info()调用：

success()调用：

error()调用：

warning()调用：

 loading()调用：

注：组件引用方法 import { rafTimeout, cancelRaf } from '../index' 请参考以下博客：

①创建全局提示组件Message：

<script setup lang="ts">
import { ref, computed, watch } from 'vue'
import { rafTimeout, cancelRaf } from '../index'
interface Props {
  duration?: number // 自动关闭的延时，单位ms
  top?: number // 消息距离顶部的位置，单位px
}
const props = withDefaults(defineProps<Props>(), {
  duration: 3000,
  top: 30
})
enum ColorStyle { // 颜色主题对象
  info = '#1677FF',
  success = '#52c41a',
  error = '#ff4d4f',
  warning = '#faad14',
  loading = '#1677FF'
}
interface Message {
  content: string
  mode: string
}
const resetTimer = ref()
const showMessage = ref<boolean[]>([])
const hideTimers = ref<any[]>([])
const messageContent = ref<Message[]>([])

const clear = computed(() => { // 所有提示是否已经全部变为false
  return showMessage.value.every(show => !show)
})
watch(clear, (to, from) => { // 所有提示都消失后重置
  if (!from && to) {
    resetTimer.value = rafTimeout(() => {
      messageContent.value.splice(0)
      showMessage.value.splice(0)
    }, 300)
  }
})
function onEnter (index: number) {
  cancelRaf(hideTimers.value[index])
}
function  onLeave (index: number) {
  onHideMessage(index)
}
function show () {
  cancelRaf(resetTimer.value)
  const index = messageContent.value.length - 1
  showMessage.value[index] = true
  onHideMessage(index)
}
function info (content: string) {
  messageContent.value.push({
    content,
    mode: 'info'
  })
  show()
}
function success (content: string) {
  messageContent.value.push({
    content,
    mode: 'success'
  })
  show()
}
function error (content: string) {
  messageContent.value.push({
    content,
    mode: 'error'
  })
  show()
}
function warning (content: string) {
  messageContent.value.push({
    content,
    mode: 'warning'
  })
  show()
}
function loading (content: string) {
  messageContent.value.push({
    content,
    mode: 'loading'
  })
  show()
}
defineExpose({
  info,
  success,
  error,
  warning,
  loading
})
const emit = defineEmits(['close'])
function onHideMessage (index: number) {
  hideTimers.value[index] = rafTimeout(() => {
    showMessage.value[index] = false
    emit('close')
  }, props.duration)
}

②在要使用的页面引入：

其中引入使用了Vue3间距（Space） 

<script setup lang="ts">
import Message from './Message.vue'
import { ref } from 'vue'
const message = ref()

function onInfo (content: string) {
  console.log('info')
  message.value.info(content) // info调用
}
function onSuccess (content: string) {
  message.value.success(content) // success调用
}
function onError (content: string) {
  message.value.error(content) // error调用
}
function onWarning (content: string) {
  message.value.warning(content) // warning调用
}
function onLoading (content: string) {
  message.value.loading(content) // loading调用
}
function onClose () {
  console.log('close')
}
</script>
<template>
  <div>
    <h1>Message 全局提示</h1>
    <h2 class="mt30 mb10">基本使用</h2>
    <Space :size="30">
      <Button type="primary" @click="onInfo('This is a normal message')">Info</Button>
      <Button type="primary" @click="onSuccess('This is a success message')">Success</Button>
      <Button type="primary" @click="onError('This is a error message')">Error</Button>

    </Space>
    <Message ref="message" :duration="3000" :top="30" @close="onClose" />
  </div>
