首先给组件全局注册（main.js）：

import Pagination from "@/components/Pagination";

组件页：

注意全局注册的名字要和组件名一致

<template>
  <div :class="{'hidden':hidden}" class="pagination-container">
    <el-pagination
      :background="background"
      :current-page.sync="currentPage"
      :page-size.sync="pageSize"
      :layout="layout"
      :page-sizes="pageSizes"
      :total="total"
      v-bind="$attrs"
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
    />
  </div>
</template>

<script>

export default {
  name: 'Pagination',
  props: {
    total: {
      required: true,
      type: Number
    },
    page: {
      type: Number,
      default: 1
    },
    limit: {
      type: Number,
      default: 20
    },
    pageSizes: {
      type: Array,
      default() {
        return [10, 20, 30, 50]
      }
    },
    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
    }
  },
  computed: {
    currentPage: {
      get() {
        return this.page
      },
      set(val) {
        this.$emit('update:page', val)
      }
    },
    pageSize: {
      get() {
        return this.limit
      },
      set(val) {
        this.$emit('update:limit', val)
      }
    }
  },
  methods: {
    handleSizeChange(val) {
      this.$emit('pagination', { page: this.currentPage, limit: val })
    },
    handleCurrentChange(val) {
      this.$emit('pagination', { page: val, limit: this.pageSize })
    }
  }
}
</script>

<style scoped>
.pagination-container {
  background: #fff;
  padding: 32px 16px;
}
.pagination-container.hidden {
  display: none;
}
</style>

父页面组件引入：

<pagination v-show="total>0" :total="total" :page.sync="queryParams.pageNum" :limit.sync="queryParams.pageSize"
      @pagination="getList" />

父页面查询列表时赋值：

getList() {
      listDbjjb(this.queryParams).then(response => {
        this.dbjjbList = response.rows
        this.total = response.total
      })
    },

父页面在data里面给初始化值：

data() {
    return {
      // 总条数
      total: 0,
      dbjjbList: [],
      // 查询参数
      queryParams: {
        pageNum: 1,
        pageSize: 10,
        fm61: undefined,
        fm62: undefined,
      },
    }
  },
