使用Vue的slot插槽分发父组件内容实现高度复用、更加灵活的组件(推荐)

 Vue.component('dialog-tip', {
   template: '#dialog-tip',
   props:['dialogShow','message'],
   data:function(){
    return {
     content:''
    }
   },
   methods:{
   }
  });

<template id="dialog-tip">
  <div class="dialog_tip" v-if="dialogShow">
   <div class="dialog_tip--mask"></div>
   <div class="dialog_tip--content">
    <div class="dialog_tip--content__txt">
     <slot name="msg">请输入1-8000之间任意整数</slot>
    </div>
    <div class="dialog_tip--content__btns">
     <slot>
      <button class="btn">确定</button>
      <button class="btn">重新输入</button>
      <button class="btn">去注册</button>
     </slot>
    </div>
   </div>
  </div>
 </template>
