Vue分页查询实现方法

基础分页实现（前端分页）

适用于数据量较小的情况，直接在Vue组件中处理分页逻辑。

<template>
  <div>
    <table>
      <tr v-for="item in paginatedData" :key="item.id">
        <td>{{ item.name }}</td>
      </tr>
    </table>
    <div class="pagination">
      <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>
  </div>
</template>

<script>
export default {
  data() {
    return {
      allData: [], // 全部数据
      currentPage: 1,
      itemsPerPage: 10
    }
  },
  computed: {
    totalPages() {
      return Math.ceil(this.allData.length / this.itemsPerPage)
    },
    paginatedData() {
      const start = (this.currentPage - 1) * this.itemsPerPage
      const end = start + this.itemsPerPage
      return this.allData.slice(start, end)
    }
  },
  methods: {
    nextPage() {
      if (this.currentPage < this.totalPages) {
        this.currentPage++
      }
    },
    prevPage() {
      if (this.currentPage > 1) {
        this.currentPage--
      }
    }
  },
  async created() {
    // 获取所有数据
    this.allData = await fetch('/api/items').then(res => res.json())
  }
}
</script>

后端分页实现（推荐）

实际项目中更常见的实现方式，通过API请求实现分页。

<template>
  <div>
    <table>
      <tr v-for="item in items" :key="item.id">
        <td>{{ item.name }}</td>
      </tr>
    </table>
    <div class="pagination">
      <button @click="prevPage" :disabled="currentPage === 1">上一页</button>
      <span>第 {{ currentPage }} 页</span>
      <button @click="nextPage" :disabled="isLastPage">下一页</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [],
      currentPage: 1,
      itemsPerPage: 10,
      totalItems: 0
    }
  },
  computed: {
    isLastPage() {
      return this.items.length < this.itemsPerPage
    }
  },
  methods: {
    async fetchData() {
      const response = await fetch(`/api/items?page=${this.currentPage}&limit=${this.itemsPerPage}`)
      const data = await response.json()
      this.items = data.items
      this.totalItems = data.total
    },
    nextPage() {
      this.currentPage++
      this.fetchData()
    },
    prevPage() {
      if (this.currentPage > 1) {
        this.currentPage--
        this.fetchData()
      }
    }
  },
  created() {
    this.fetchData()
  }
}
</script>

使用第三方组件库

Element UI的分页组件实现示例：

<template>
  <div>
    <el-table :data="tableData">
      <el-table-column prop="name" label="名称"></el-table-column>
    </el-table>
    <el-pagination
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-size="pageSize"
      :total="total"
      layout="prev, pager, next">
    </el-pagination>
  </div>
</template>

<script>
export default {
  data() {
    return {
      tableData: [],
      currentPage: 1,
      pageSize: 10,
      total: 0
    }
  },
  methods: {
    handleCurrentChange(val) {
      this.currentPage = val
      this.fetchData()
    },
    async fetchData() {
      const res = await this.$http.get('/api/items', {
        params: {
          page: this.currentPage,
          size: this.pageSize
        }
      })
      this.tableData = res.data.items
      this.total = res.data.total
    }
  },
  created() {
    this.fetchData()
  }
}
</script>
