Vue 自定义全局message组件

Posted 2021-01-06 conglvse

Message.vue

<template>
  <transition name="fade">
    <div class="message" :class="type" v-if="visible">
      <i class="icon-type iconfont" :class="‘icon-‘+type"></i>
      <div class="content">{{content}}
        <i v-if="hasClose" class="btn-close iconfont icon-close" @click="visible=false"></i>
      </div>
    </div>
  </transition>
</template>

<script>
  export default {
    name: "MyMessage",
    data() {
      return {
        content: ‘‘,
        time: 3000,
        visible: false,
        type:‘info‘,//‘success‘,‘warning‘,‘error‘
        hasClose:false,
      }
    },
    mounted() {
      this.close()
    },
    methods: {
      close() {
        window.setTimeout(() =>{
          this.visible = false
        }, this.time);
      }
    }
  }
</script>

index.js
给Vue添加$my_message方法,
判断参数，使用$mount()给组件手动挂载参数，然后将组件插入页面中

import Vue from ‘vue‘
import Message from ‘./Message.vue‘

Vue.prototype.$my_message = function(options) {
  if (options === undefined || options === null) {
    options = {
      content: ‘‘
    }
  } else if (typeof options === ‘string‘ || typeof options === ‘number‘) {
    options = {
      content: options
    }
  }
  var message = Vue.extend(Message)
  var component = new message({
    data: options
  }).$mount()
  document.body.appendChild(component.$el)
  Vue.nextTick(() => {
    component.visible = true
  })
}
Message.install=function(Vue){
  Vue.component(Message.name,Message);
}
export default Message

在main.js里全局引入

import Message from ‘@/components/common/message‘
Vue.use(Message)

页面中调用

this.$my_message(‘这是一个message‘);
//传参的方式
this.$my_message({
    content:‘这是一个success提示‘,
    time:5000000,
    type:‘success‘,
    hasClose:true,
});
