vue翻页实现

Vue翻页实现方法

基础分页组件实现

使用v-for和计算属性实现基础分页逻辑：

<template>
  <div>
    <ul>
      <li v-for="item in paginatedData" :key="item.id">{{ item.name }}</li>
    </ul>
    <button @click="prevPage" :disabled="currentPage === 1">上一页</button>
    <span>第 {{ currentPage }} 页</span>
    <button @click="nextPage" :disabled="currentPage === totalPages">下一页</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [], // 原始数据
      currentPage: 1,
      itemsPerPage: 10
    }
  },
  computed: {
    totalPages() {
      return Math.ceil(this.items.length / this.itemsPerPage)
    },
    paginatedData() {
      const start = (this.currentPage - 1) * this.itemsPerPage
      const end = start + this.itemsPerPage
      return this.items.slice(start, end)
    }
  },
  methods: {
    nextPage() {
      this.currentPage++
    },
    prevPage() {
      this.currentPage--
    }
  }
}
</script>

使用第三方库

对于复杂分页需求，可以使用专门的分页库：

npm install vuejs-paginate

实现示例：

<template>
  <div>
    <paginate
      :page-count="totalPages"
      :click-handler="changePage"
      :prev-text="'<'"
      :next-text="'>'"
      :container-class="'pagination'"
    >
    </paginate>
  </div>
</template>

<script>
import Paginate from 'vuejs-paginate'
export default {
  components: { Paginate },
  methods: {
    changePage(pageNum) {
      this.currentPage = pageNum
    }
  }
}
</script>

服务器端分页

当数据量较大时，建议采用API分页：

methods: {
  async fetchData(page = 1) {
    const res = await axios.get(`/api/items?page=${page}&limit=10`)
    this.items = res.data.items
    this.totalPages = res.data.totalPages
  }
}

分页样式优化

添加CSS美化分页控件：

.pagination {
  display: flex;
  list-style: none;
  padding: 0;
}
.pagination li {
  margin: 0 5px;
  cursor: pointer;
}
.pagination li.active {
  font-weight: bold;
}

动态分页大小

允许用户选择每页显示数量：

<select v-model="itemsPerPage" @change="resetPagination">
  <option value="5">5条/页</option>
  <option value="10">10条/页</option>
  <option value="20">20条/页</option>
</select>

methods: {
  resetPagination() {
    this.currentPage = 1
  }
}
