vue2.0實現分頁組件的實例代碼

這篇文章主要介紹了vue2.0實現分頁組件的實例代碼,需要的朋友可以參考下

最近使用vue2.0重構項目, 需要實現一個分頁的表格, 沒有找到合適的分頁組件, 就自己寫了一個, 效果如下:

該項目是使用 vue-cli搭建的, 如果你的項目中沒有使用webpack,請根據代碼自己調整:

首先新建pagination.vue文件, 所有組件的代碼都寫在這里, 寫這樣的組件并沒有什么太大的難度, 主要是解決父子組件之間值傳遞的問題

<template>
 <nav>
  <ul class="pagination">
   <li :class="{'disabled': current == 1}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(current - 1)"> « </a></li>
   <li :class="{'disabled': current == 1}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(1)"> 首頁 </a></li>
   <li v-for="p in grouplist" :class="{'active': current == p.val}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" 
                                     @click="setCurrent(p.val)"> {{ p.text }} </a>
   </li>
   <li :class="{'disabled': current == page}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(page)"> 尾頁 </a></li>
   <li :class="{'disabled': current == page}"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="setCurrent(current + 1)"> »</a></li>
  </ul>
 </nav>
</template>
<script type="es6">
 export default{
  data(){
   return {
    current: this.currentPage
   }
  },
  props: {
   total: {// 數據總條數
    type: Number,
    default: 0
   },
   display: {// 每頁顯示條數
    type: Number,
    default: 10
   },
   currentPage: {// 當前頁碼
    type: Number,
    default: 1
   },
   pagegroup: {// 分頁條數
    type: Number,
    default: 5,
    coerce: function (v) {
     v = v > 0 ? v : 5;
     return v % 2 === 1 ? v : v + 1;
    }
   }
  },
  computed: {
   page: function () { // 總頁數
    return Math.ceil(this.total / this.display);
   },
   grouplist: function () { // 獲取分頁頁碼
    var len = this.page, temp = [], list = [], count = Math.floor(this.pagegroup / 2), center = this.current;
    if (len <= this.pagegroup) {
     while (len--) {
      temp.push({text: this.page - len, val: this.page - len});
     }
     ;
     return temp;
    }
    while (len--) {
     temp.push(this.page - len);
    }
    ;
    var idx = temp.indexOf(center);
    (idx < count) && ( center = center + count - idx);
    (this.current > this.page - count) && ( center = this.page - count);
    temp = temp.splice(center - count - 1, this.pagegroup);
    do {
     var t = temp.shift();
     list.push({
      text: t,
      val: t
     });
    } while (temp.length);
    if (this.page > this.pagegroup) {
     (this.current > count + 1) && list.unshift({text: '...', val: list[0].val - 1});
     (this.current < this.page - count) && list.push({text: '...', val: list[list.length - 1].val + 1});
    }
    return list;
   }
  },
  methods: {
   setCurrent: function (idx) {
    if (this.current != idx && idx > 0 && idx < this.page + 1) {
     this.current = idx;
     this.$emit('pagechange', this.current);
    }
   }
  }
 }
</script>
<style lang="less">
 .pagination {
  overflow: hidden;
  display: table;
  margin: 0 auto;
  /*width: 100%;*/
  height: 50px;
 li {
  float: left;
  height: 30px;
  border-radius: 5px;
  margin: 3px;
  color: #666;
 &
 :hover {
  background: #000;
 a {
  color: #fff;
 }
 }
 a {
  display: block;
  width: 30px;
  height: 30px;
  text-align: center;
  line-height: 30px;
  font-size: 12px;
  border-radius: 5px;
  text-decoration: none
 }
 }
 .active {
  background: #000;
 a {
  color: #fff;
 }
 }
 }
</style>

使用時, 在父組件中引入, 代碼如下:

<template>
        <v-pagination :total="total" :current-page='current' @pagechange="pagechange"></v-pagination>
</template>
<script type="es6">
import pagination from '@/components/common/pagination/pagination'
export default{
    data(){
return {
        total: 150,     // 記錄總條數
        display: 10,   // 每頁顯示條數
        current: 1,   // 當前的頁數
},
methods: {
     pagechange:function(currentPage){
       console.log(currentPage);
       // ajax請求, 向后臺發(fā)送 currentPage, 來獲取對應的數據
     }
   },
components: {
      'v-pagination': pagination,
    }
}
</script>
