vue实现前端分页

Vue 前端分页实现方法

基础数据分页

1. 准备分页数据

   data() {
   return {
    allItems: [], // 原始数据
    currentPage: 1, // 当前页码
    itemsPerPage: 10 // 每页条数
   }
   }

2. 计算分页数据

   

   computed: {
   paginatedItems() {
    const start = (this.currentPage - 1) * this.itemsPerPage
    const end = start + this.itemsPerPage
    return this.allItems.slice(start, end)
   },
   totalPages() {
    return Math.ceil(this.allItems.length / this.itemsPerPage)
   }
   }

3. 分页控件模板

   

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

高级分页组件

1. 创建可复用分页组件

   // Pagination.vue
   props: {
   totalItems: Number,
   itemsPerPage: Number,
   currentPage: Number
   },
   computed: {
   totalPages() {
    return Math.ceil(this.totalItems / this.itemsPerPage)
   }
   },
   methods: {
   changePage(page) {
    this.$emit('page-changed', page)
   }
   }

2. 使用分页组件

   <pagination
   :total-items="allItems.length"
   :items-per-page="itemsPerPage"
   :current-page="currentPage"
   @page-changed="currentPage = $event"
   />

分页样式优化

.pagination {
  display: flex;
  justify-content: center;
  margin-top: 20px;
}
.pagination button {
  margin: 0 5px;
  padding: 5px 10px;
}
.pagination button:disabled {
  opacity: 0.5;
  cursor: not-allowed;
}

分页逻辑优化

methods: {
  prevPage() {
    if (this.currentPage > 1) {
      this.currentPage--
    }
  },
  nextPage() {
    if (this.currentPage < this.totalPages) {
      this.currentPage++
    }
  },
  goToPage(page) {
    if (page >= 1 && page <= this.totalPages) {
      this.currentPage = page
    }
  }
}

带页码显示的分页

<div class="page-numbers">
  <span 
    v-for="page in totalPages" 
    :key="page"
    @click="goToPage(page)"
    :class="{ active: page === currentPage }"
  >
    {{ page }}
  </span>
</div>

与后端API结合

async fetchData() {
  const response = await axios.get('/api/items', {
    params: {
      page: this.currentPage,
      limit: this.itemsPerPage
    }
  })
  this.allItems = response.data.items
  this.totalItems = response.data.total
}

这些方法可以根据实际需求组合使用，实现从简单到复杂的前端分页功能。
