vue編寫messageBox，使用函數調用

效果如下：

調用：

this.$messageBox({
  text: '123123213',
  callback:action=>{
    console.log(action);//confirm(确定)cancel（确定）
  }
})      

代碼：

messageBox.js

import  messageBoxVue from './messageBox.vue'
export default {
  install(Vue){
    let messageBox = Vue.extend(messageBoxVue);
    let $messageBox = new messageBox();
    document.body.appendChild($messageBox.$mount().$el);
    Vue.prototype.$messageBox = (model => {
      model.show=true;
      $messageBox.model=model;
    });
  }
}      

messageBox.vue:

<template>
  <div>
    <transition name="bounce">
      <div v-show="model.show" class="messageBox">
        <div class="messageBox_header">
          <div class="messageBox_header_title">
            提示
          </div>
        </div>

        <div class="messageBox_content">
          {{model.text}}
          <div v-html="model.html"></div>
        </div>
        <div class="messageBox_btns">
          <div class="messageBox_btns_default messageBox_btns_primary" @click="close('confirm')">确定</div>
          <div class="messageBox_btns_default " @click="close('cancel')">取消</div>
        </div>
      </div>
    </transition>
    <div v-show="model.show" class="messageBox_model"></div>
  </div>
</template>

<script>
  export default {
    name: 'messageBox',
    data(){
      return {
        model: {
          show: ''
        }
      }
    },
    methods: {
      close(state){
        this.model.show = false;
        if(this.model.callback){
          this.model.callback(state);
        }
      },
    }
  }
</script>
