Vue 分页组件实现

分页组件模板

分页组件通常包含页码按钮、上一页/下一页按钮和跳转功能。以下是一个基础模板结构：

<template>
  <div class="pagination">
    <button 
      :disabled="currentPage === 1" 
      @click="changePage(currentPage - 1)"
    >
      上一页
    </button>

    <button
      v-for="page in pages"
      :key="page"
      :class="{ active: currentPage === page }"
      @click="changePage(page)"
    >
      {{ page }}
    </button>

    <button
      :disabled="currentPage === totalPages"
      @click="changePage(currentPage + 1)"
    >
      下一页
    </button>

    <span class="page-info">
      第 {{ currentPage }} 页 / 共 {{ totalPages }} 页
    </span>
  </div>
</template>

分页逻辑实现

核心分页逻辑通过计算属性和方法实现：

<script>
export default {
  props: {
    totalItems: {
      type: Number,
      required: true
    },
    itemsPerPage: {
      type: Number,
      default: 10
    },
    currentPage: {
      type: Number,
      default: 1
    },
    maxVisiblePages: {
      type: Number,
      default: 5
    }
  },
  computed: {
    totalPages() {
      return Math.ceil(this.totalItems / this.itemsPerPage)
    },
    pages() {
      const range = []
      const half = Math.floor(this.maxVisiblePages / 2)
      let start = Math.max(this.currentPage - half, 1)
      const end = Math.min(start + this.maxVisiblePages - 1, this.totalPages)

      if (end - start + 1 < this.maxVisiblePages) {
        start = Math.max(end - this.maxVisiblePages + 1, 1)
      }

      for (let i = start; i <= end; i++) {
        range.push(i)
      }
      return range
    }
  },
  methods: {
    changePage(page) {
      if (page >= 1 && page <= this.totalPages) {
        this.$emit('page-changed', page)
      }
    }
  }
}
</script>

样式设计

基础样式确保分页组件美观可用：

<style scoped>
.pagination {
  display: flex;
  align-items: center;
  gap: 8px;
  margin-top: 20px;
}

button {
  padding: 6px 12px;
  border: 1px solid #ddd;
  background: white;
  cursor: pointer;
  border-radius: 4px;
}

button:hover:not(:disabled) {
  background: #f0f0f0;
}

button.active {
  background: #1890ff;
  color: white;
  border-color: #1890ff;
}

button:disabled {
  opacity: 0.5;
  cursor: not-allowed;
}

.page-info {
  margin-left: 12px;
  font-size: 14px;
}
</style>

父组件集成

在父组件中使用分页组件并处理数据分页：

<template>
  <div>
    <!-- 数据列表展示 -->
    <ul>
      <li v-for="item in paginatedData" :key="item.id">
        {{ item.name }}
      </li>
    </ul>

    <!-- 分页组件 -->
    <Pagination
      :total-items="data.length"
      :items-per-page="perPage"
      :current-page="currentPage"
      @page-changed="handlePageChange"
    />
  </div>
</template>

<script>
import Pagination from './Pagination.vue'

export default {
  components: { Pagination },
  data() {
    return {
      data: [], // 从API获取的实际数据
      perPage: 10,
      currentPage: 1
    }
  },
  computed: {
    paginatedData() {
      const start = (this.currentPage - 1) * this.perPage
      const end = start + this.perPage
      return this.data.slice(start, end)
    }
  },
  methods: {
    handlePageChange(page) {
      this.currentPage = page
      // 可选: 这里可以触发API请求获取新页数据
    }
  },
  async created() {
    // 示例数据获取
    this.data = await fetchData()
  }
}
</script>
