在vue中如何实现分页组件

<page :total=&#39;total&#39; :current-index="currentIndex" :listLen=&#39;listLen&#39; @getPage=&#39;getPage&#39;></page>

<ul class="item" v-show="arr.length">
    <li @click="start">首页</li>
    <li @click="pre"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><<</a></li>  上一列表页
    <li @click="currentPre"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><</a></li>   点解当前列表页上一页
    <li v-for="(item,index) in arr" :class="{active: item===num}" @click="getPage(item)">{{item}}</li>
    <li @click="currentNext"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >></a></li>  点解当前列表页下一页
    <li @click="next"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >>></a></li>  下一列表页
    <li @click="end">尾页</li>
  </ul>

data() {
  return {
   num: Number, //表示当前页码高亮
   arr: [], //页面显示的数组
   page: Number, //一页显示多少个,可以自定义,不能大于总页码
   Remainder:Number, //是否整除
   merchant:Number, // 比较总页数和page页
  };
 },
 props: {
  //分页的总数
  total: {
   type: Number,
   default: 5
  },
  //当前页
  currentIndex: {
   type: Number,
   default: 1
  },
  //一个列表页显示多少页码
  listLen:{
   type: Number,
   default: 5
  }
 },
