vue实现分页组件

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"></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"></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 ? this.page.totalCount % this.condition.pageSize === 0 ? 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>
