vue3封装分页组件

来源：刀刀网

1.新建Pagination文件以及该文件夹下新建index.vue

2.在index.vue文件中编写一下代码

<template>
  <div :class="{ 'hidden': hidden }" class="pagination-container">
    <el-pagination
      :background="background"
      v-model:current-page="currentPage"
      v-model:page-size="pageSize"
      :layout="layout"
      :page-sizes="pageSizes"
      :pager-count="pagerCount"
      :total="+total"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
    />
  </div>
</template>

<script setup>
import { scrollTo } from '@/utils/scroll-to'

const props = defineProps({
  total: {
    required: true,
    type: Number
  },
  page: {
    type: Number,
    default: 1
  },
  limit: {
    type: Number,
    default: 20
  },
  pageSizes: {
    type: Array,
    default() {
      return [30, 60, 100]
    }
  },
  // 移动端页码按钮的数量端默认值5
  pagerCount: {
    type: Number,
    default: document.body.clientWidth < 992 ? 5 : 7
  },
  layout: {
    type: String,
    default: 'total, sizes, prev, pager, next, jumper'
  },
  background: {
    type: Boolean,
    default: true
  },
  autoScroll: {
    type: Boolean,
    default: true
  },
  hidden: {
    type: Boolean,
    default: false
  }
})

const emit = defineEmits();
const currentPage = computed({
  get() {
    return props.page
  },
  set(val) {
    emit('update:page', val)
  }
})
const pageSize = computed({
  get() {
    return props.limit
  },
  set(val){
    emit('update:limit', val)
  }
})
function handleSizeChange(val) {
  if (currentPage.value * val > props.total) {
    currentPage.value = 1
  }
  emit('pagination', { page: currentPage.value, limit: val })
  if (props.autoScroll) {
    scrollTo(0, 800)
  }
}
function handleCurrentChange(val) {
  emit('pagination', { page: val, limit: pageSize.value })
  if (props.autoScroll) {
    scrollTo(0, 800)
  }
}

</script>

<style scoped>
.demo-pagination-block {
  position: fixed;
  bottom: 20px;
  right: 20px;
  width: 50vw;
  padding-bottom: 20px;
  background: #fff;
  z-index: 99;

  .pagination-container {
    margin-top: 0;
  }
}
.pagination-container {
  background: #fff;
  padding: 0 16px 20px;
}
.pagination-container.hidden {
  display: none;
}
</style>

3.使用封装的组件

<div class="demo-pagination-block">
 <pagination :total="data.total" v-model:page="searchParams.pageNum" v-model:limit="searchParams.pageSize"
 @pagination="getList" />
</div>

import { pageList } from '@/api/dataScheduling/portDataList'

const searchParams = reactive({
    containerNo: '', // 集装箱号
    searchDate: '', // 筛选时间
    dataStatus: '', // 状态
    shipName: '', // 船名
    destinationPort: '', // 目的港
    pageNum: 1, // 页码
    pageSize: 30, // 条数
});

const data = reactive({
    total: 10, // 总条数
    tableData: [], // 数据列表
});
onMounted(() => {
    getList();
});

// 获取数据列表
const getList = () => {
    let params = { ...searchParams }
    pageList(params).then(res => {
        console.log('获取列表', res);
        data.tableData = res.rows
        data.total = res.total
    })
};
