优化elementUI的Message消息提示连续触发，满屏显示问题

elMessage.js

import {Message} from 'element-ui'
const tipsEvent=(options)=>{
    console.log(document.querySelectorAll('.el-message'));
    const dom=document.querySelectorAll('.el-message')[0]
    if(dom==undefined){
        Message(options)
    }
}
const typeList=['success','error','info','warning']
typeList.forEach(item=>{
    tipsEvent[item]=options=>{
        const ele=document.querySelectorAll('.el-message')[0]
        if(ele==undefined){
            Message[item](options)
        }
    }
})
export const tips=tipsEvent

main.js中全局挂载

import Vue from 'vue'
import {tips} from '@/utils/elMessage.js'

Vue.prototype.$message=tips;//在这里建议取相同的名称，因为是为了覆盖框架默认的this.$message

index.vue中使用

<script>
    export default {
        name: 'index',
        methods: {
            handleTap(){
              this.$message({
                type:'warning',
                message:'警告提示触发了'
              })
            }
        }
    }
</script>
