vue 公用组件开发 消息提示$message

文件目录：

github地址：https://github.com/xingkongwuyu/vue-spa-experience/tree/master/src/components/message

最终的效果：

 这里的样式颜色啥的写的比较草率了，图标也选的比较草率，我需要一个ui设计师，没有的话我只能随便打打颜色了

 组件的源码解析：

message：  message的框架

./index.js

import messageBox from './src/index';
export default {
    install(Vue) {
      Vue.prototype.$message = messageBox;
    },
  };

使用transition来实现动画效果

<template>
  <transition name="mei-message-fade">
    <div v-if="show" :class="[
        'mei-message',
        type? `mei-message-${ type }` : '']"
      >
      <i v-if="type=='error'" class="mei-message-icon">

    let instance = new messageVueConstructor({

        instance.close();
      },options.duration)

    return instance;
  };
  
  export default messageBox;

引入全局 使用：

import VueMessage from './components/message'

Vue.use(VueMessage)

 message () {
         this.$message({
          type:'success',
          text:11111,
        });
},

             配置项：

      type：类型【success，error，info，warning】

      button：按钮
      text：内容

      duration:时间

      这里type类型你们可以去找找好看的我就是随便乱弄了下   iconfont 另外我就找了success和error的icon比较草率；
