实现Vue分页条的方法

使用Element UI的Pagination组件

安装Element UI库后，可以直接使用其分页组件。示例代码如下：

<template>
  <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>
</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() {
      // 调用API获取数据
    }
  }
}
</script>

自定义分页组件

如果需要完全自定义样式和功能，可以手动实现分页逻辑：

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

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

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

<script>
export default {
  props: {
    totalItems: Number,
    itemsPerPage: Number
  },
  data() {
    return {
      currentPage: 1
    }
  },
  computed: {
    totalPages() {
      return Math.ceil(this.totalItems / this.itemsPerPage)
    },
    pageRange() {
      const range = []
      for (let i = 1; i <= this.totalPages; i++) {
        range.push(i)
      }
      return range
    }
  },
  methods: {
    prevPage() {
      if (this.currentPage > 1) {
        this.currentPage--
        this.$emit('page-changed', this.currentPage)
      }
    },
    nextPage() {
      if (this.currentPage < this.totalPages) {
        this.currentPage++
        this.$emit('page-changed', this.currentPage)
      }
    },
    goToPage(page) {
      this.currentPage = page
      this.$emit('page-changed', page)
    }
  }
}
</script>

<style>
.pagination {
  display: flex;
  gap: 8px;
}
.active {
  font-weight: bold;
  color: blue;
}
</style>

与后端API配合

实际项目中通常需要结合后端API实现分页：

methods: {
  async fetchData() {
    const res = await axios.get('/api/data', {
      params: {
        page: this.currentPage,
        size: this.pageSize
      }
    })
    this.data = res.data.items
    this.total = res.data.total
  }
}
