vue实现分页功能例子

以下是一个基于 Vue 3 的分页功能实现示例，包含基本逻辑和样式：

基础实现代码

<template>
  <div class="pagination-container">
    <button 
      @click="prevPage" 
      :disabled="currentPage === 1"
    >上一页</button>

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

    <button 
      @click="nextPage" 
      :disabled="currentPage === totalPages"
    >下一页</button>
  </div>
</template>

<script setup>
import { ref, computed } from 'vue';

const props = defineProps({
  totalItems: {
    type: Number,
    required: true
  },
  itemsPerPage: {
    type: Number,
    default: 10
  }
});

const currentPage = ref(1);

const totalPages = computed(() => 
  Math.ceil(props.totalItems / props.itemsPerPage)
);

const visiblePages = computed(() => {
  const pages = [];
  const maxVisible = 5;
  let start = Math.max(1, currentPage.value - Math.floor(maxVisible / 2));
  let end = Math.min(totalPages.value, start + maxVisible - 1);

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

  for (let i = start; i <= end; i++) {
    pages.push(i);
  }
  return pages;
});

function prevPage() {
  if (currentPage.value > 1) {
    currentPage.value--;
  }
}

function nextPage() {
  if (currentPage.value < totalPages.value) {
    currentPage.value++;
  }
}

function goToPage(page) {
  currentPage.value = page;
}
</script>

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

button {
  padding: 4px 8px;
  cursor: pointer;
}

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

span {
  padding: 4px 8px;
  cursor: pointer;
}

span.active {
  font-weight: bold;
  color: #42b983;
}
</style>

使用示例

<template>
  <div>
    <!-- 显示分页数据 -->
    <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="itemsPerPage"
      @page-change="handlePageChange"
    />
  </div>
</template>

<script setup>
import { ref, computed } from 'vue';
import Pagination from './Pagination.vue';

const data = ref([
  { id: 1, name: 'Item 1' },
  // ...更多数据
]);

const itemsPerPage = 5;
const currentPage = ref(1);

const paginatedData = computed(() => {
  const start = (currentPage.value - 1) * itemsPerPage;
  const end = start + itemsPerPage;
  return data.value.slice(start, end);
});

function handlePageChange(page) {
  currentPage.value = page;
}
</script>

高级功能扩展

添加每页条数选择器：

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

添加跳转输入框：

<input 
type="number" 
v-model="inputPage" 
min="1" 
:max="totalPages"
@keyup.enter="goToInputPage"
>

添加省略号显示：

const visiblePages = computed(() => {
// ...原有逻辑
if (start > 1) pages.unshift('...');
if (end < totalPages.value) pages.push('...');
return pages;
});
