  transition: all .3s;
}
.msgbox-enter-to,.msgbox-leave{

}
</style>

最后在 main.js 里面 配置 

import emComponent from './components/custom/index'
Vue.use(emComponent)

 

具体使用方法

<template>
  <div>
    <label id="msgbox" @click.stop="showMsgbox">点击我显示msgbox</label>
  </div>
</template>
<script>

<script>
export default {
  name: 'test',
  data(){
    return {

    }
  },
  methods:{
    showMsgbox(){
      this.$msgbox({
          title:'温馨提示',
          cancel:'取消',
          content:'这里是消息弹出内容',
          confirm:'确定按钮',
          className:'pop-custom'
      }).then(()=>{
          console.log("我点击了确定按钮")
      }).catch((err)=>{
