vue中实现分页的方法

使用Element UI的分页组件

Element UI提供了现成的分页组件el-pagination，适合快速集成。需先安装Element UI库。

安装命令：

npm install element-ui

示例代码：

<template>
  <div>
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[10, 20, 30, 40]"
      :page-size="pageSize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="total">
    </el-pagination>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentPage: 1,
      pageSize: 10,
      total: 100
    }
  },
  methods: {
    handleSizeChange(val) {
      this.pageSize = val;
      this.fetchData();
    },
    handleCurrentChange(val) {
      this.currentPage = val;
      this.fetchData();
    },
    fetchData() {
      // 根据currentPage和pageSize请求数据
    }
  }
}
</script>

自定义分页组件

如果需要更灵活的控制，可以手动实现分页逻辑。

示例代码：

<template>
  <div>
    <ul>
      <li v-for="item in paginatedData" :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>

<script>
export default {
  data() {
    return {
      data: [], // 所有数据
      currentPage: 1,
      pageSize: 10
    }
  },
  computed: {
    totalPages() {
      return Math.ceil(this.data.length / this.pageSize);
    },
    paginatedData() {
      const start = (this.currentPage - 1) * this.pageSize;
      const end = start + this.pageSize;
      return this.data.slice(start, end);
    }
  },
  methods: {
    prevPage() {
      if (this.currentPage > 1) {
        this.currentPage--;
      }
    },
    nextPage() {
      if (this.currentPage < this.totalPages) {
        this.currentPage++;
      }
    }
  }
}
</script>

结合后端API实现分页

实际项目中，通常需要从后端获取分页数据。

示例代码：

<template>
  <div>
    <el-pagination
      @current-change="handlePageChange"
      :current-page="currentPage"
      :page-size="pageSize"
      :total="total"
      layout="prev, pager, next">
    </el-pagination>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentPage: 1,
      pageSize: 10,
      total: 0,
      list: []
    }
  },
  mounted() {
    this.fetchData();
  },
  methods: {
    fetchData() {
      const params = {
        page: this.currentPage,
        size: this.pageSize
      };
      axios.get('/api/data', { params })
        .then(response => {
          this.list = response.data.list;
          this.total = response.data.total;
        });
    },
    handlePageChange(page) {
      this.currentPage = page;
      this.fetchData();
    }
  }
}
</script>

分页样式优化

可以通过CSS美化分页组件，例如添加过渡效果或调整按钮样式。

示例CSS：

.pagination {
  display: flex;
  justify-content: center;
  margin-top: 20px;
}
.pagination button {
  margin: 0 5px;
  padding: 5px 10px;
  border: 1px solid #ddd;
  background: #fff;
  cursor: pointer;
}
.pagination button:disabled {
  cursor: not-allowed;
  opacity: 0.5;
}
