不懂vue实现分页组件的源代码是什么？？其实想解决这个问题也不难，下面让小编带着大家一起学习怎么去解决，希望大家阅读完这篇文章后大所收获。

本文实例为大家分享了vue实现分页组件的具体代码，供大家参考，具体内容如下

<template>
 <div class="pageBox">
 <ul>
  <li v-if="this.condition.pageNo > 1 && this.pages.length > 4" class="sides"><a @click="prePage()"><s class="font_main">&#xe629;</s></a></li>
  <li v-for="(item, index) in pages" :class="{'curtPage': condition.pageNo == item}">
  <a v-if="item" @click="goPage(item)" >
   <s>{{item}}</s>
  </a>
  <a href="javascript:;" rel="external nofollow" v-else>...</a>
  </li>
  <li class="sides" v-if="condition.pageNo < pageCount && this.pageCount > 4"><a @click="nextPage()"><s class="font_main">&#xe62f;</s></a></li>
 </ul>
 </div>
</template>

js中代码 page 和condition是由父组件中传过来的参数

<script>
 export default {
 props: {
  page: Object,
  condition: Object
 },
 data () {
  return {
  pageSize: this.condition.pageSize
  }
 },
 computed: {
  pageCount: function () {
  return this.page.totalCount / this.condition.pageSize > 0 &#63; this.page.totalCount % this.condition.pageSize === 0 &#63; this.page.totalCount / this.condition.pageSize : Math.ceil(this.page.totalCount / this.condition.pageSize) : 1
  },
  pages () {
  let c = this.condition.pageNo
  let t = this.pageCount
  let arr = []
  if (t === 1) {
   return arr
  }
  if (t <= 4) {
   for (let i = 1; i <= t; i++) {
   arr.push(i)
   }
   return arr
  }
  if (c <= 3) return [1, 2, 3, 0, t]
  if (c >= t - 1) return [1, 0, t - 2, t - 1, t]
//  if (c === 4) return [1, 2, 3, 4, 5, 0, t]
//  if (c === (t - 2)) return [1, 0, t - 3, t - 2, t - 1, t]
  return [1, 0, c - 1, c, c + 1, 0, t]
  }
 },
 methods: {
  goPage (indexPage) {
  if (this.indexPage !== this.condition.pageNo) {
   this.condition.pageNo = indexPage
   this.$emit('search')
  }
  },
  prePage () {
  if (this.condition.pageNo !== 1) {
   this.condition.pageNo--
   this.goPage(this.condition.pageNo)
  }
  },
  nextPage () {
  if (this.condition.pageNo !== this.pageCount) {
   this.condition.pageNo++
   this.goPage(this.condition.pageNo)
  }
  }
 }
 }
</script>
