vue2 element UI 成果：

分页组件 /components/Pagination.vue

<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 {
  props: {
    total: {
      type: Number,
      required: true,
    },
    pageSize: {
      type: Number,
      required: true,
      default: 10,
    },
    currentPage: {
      type: Number,
      required: true,
      default: 1,
    },
  },
  methods: {
    handleSizeChange(val) {
      this.$emit("update:pageSize", val);
    },
    handleCurrentChange(val) {
      this.$emit("update:currentPage", val);
    },
  },
};
</script>

<style scoped lang="scss"></style>

父组件 /index.vue

    <PaginationVue
