使用Vue实现分页加载

安装依赖

确保项目中已安装axios用于数据请求，若未安装可通过以下命令安装：

npm install axios

基本分页组件结构

在Vue组件中定义分页所需的数据和方法：

用vue实现加载分页

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

<script>
import axios from 'axios';

export default {
  data() {
    return {
      items: [],
      currentPage: 1,
      totalPages: 1,
      perPage: 10
    };
  },
  methods: {
    fetchData() {
      axios.get(`/api/items?page=${this.currentPage}&per_page=${this.perPage}`)
        .then(response => {
          this.items = response.data.data;
          this.totalPages = response.data.total_pages;
        });
    },
    nextPage() {
      if (this.currentPage < this.totalPages) {
        this.currentPage++;
        this.fetchData();
      }
    },
    prevPage() {
      if (this.currentPage > 1) {
        this.currentPage--;
        this.fetchData();
      }
    }
  },
  created() {
    this.fetchData();
  }
};
</script>

后端API示例

假设后端使用类似RESTful的接口，返回格式如下：

{
  "data": [...],
  "total_pages": 5
}

优化加载体验

添加加载状态提示，避免用户重复点击：

用vue实现加载分页

data() {
  return {
    isLoading: false
  };
},
methods: {
  fetchData() {
    this.isLoading = true;
    axios.get(...)
      .then(...)
      .finally(() => {
        this.isLoading = false;
      });
  }
}

分页样式优化

使用CSS美化分页按钮，例如：

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

动态页码显示

扩展分页组件，显示更多页码选项：

<template>
  <div class="pagination">
    <button @click="goToPage(1)" :disabled="currentPage === 1">首页</button>
    <button v-for="page in visiblePages" 
            @click="goToPage(page)"
            :class="{ active: currentPage === page }">
      {{ page }}
    </button>
    <button @click="goToPage(totalPages)" :disabled="currentPage === totalPages">末页</button>
  </div>
</template>

computed: {
  visiblePages() {
    const range = 2; // 显示当前页前后各2页
    let start = Math.max(1, this.currentPage - range);
    let end = Math.min(this.totalPages, this.currentPage + range);
    return Array.from({ length: end - start + 1 }, (_, i) => start + i);
  }
}
