Vue3.x+Element Plus仿制Acro Design简洁模式实现分页器组件

开发中难免会遇到宽度很窄的列表需要使用分页器的情况，这时若使用Element Plus组件的分页器会导致分页器内容超出展示的区域，而Element Plus组件中目前没有Acro Design那样小巧的分页器（Arco Design Vue）如下图所示，如果再引入一个新的UI组件库未免导致项目臃肿，所以基于Vue3.x和Element Plus封装了一个即拿即用的”简洁模式“分页器组件以便不时之需

分页器组件代码部分：

<!-- （简洁模式）分页器组件 --><template>  <div>    <!-- 总数统计 -->    <span>{{ "共" + total + "条" }}</span>    <!-- 翻页 -->    <div>      <!-- 左翻页 -->      <el-icon @click="pageTurning("down")" :class="curPage <= 1 ? "forbid-pageturning" : """><ArrowLeft />      </el-icon>      <!-- 页码 -->      <el-input-number @change="handlePageChange" v-model="pageNum" :min="1" :max="pageTotal" :step-strictly="true":controls="false" />      <b>{{ "/ " + pageTotal }}</b>      <!-- 右翻页 -->      <el-icon @click="pageTurning("up")" :class="curPage >= pageTotal ? "forbid-pageturning" : """><ArrowRight />      </el-icon>    </div>  </div></template><script setup>import { useAttrs, computed, ref } from "vue";import {  ArrowLeft,  ArrowRight} from "@element-plus/icons-vue";// 接收父组件参数const attrs = useAttrs();// 父组件事件const em = defineEmits(["handlePageChange"]);// 当前页const pageNum = ref(1);// 父组件传递-当前页码const curPage = computed(() => {  pageNum.value = attrs.curPage;  return attrs.curPage;});// 父组件传递-总数const total = computed(() => {  return attrs.total;});// 总页码数const pageTotal = computed(() => {  return attrs.total > 0 ? Math.ceil(attrs.total / attrs.pageSize) : 1;});/* 改变页码 */const handlePageChange = (e) => {  if (pageTotal.value <= 1) {    return;  }  em("handlePageChange", e);};/* 翻页 */const pageTurning = (type) => {  // 向前翻页  if (type === "up") {    if (curPage.value >= pageTotal.value || pageTotal.value <= 1) {      return;    }    em("handlePageChange", pageNum.value + 1);  }  // 向后翻页  else {    if (pageTotal.value <= 1 || curPage.value <= 1) {      return;    }    em("handlePageChange", pageNum.value - 1);  }};</script><style lang="less" scoped>.smallpagination {  width: auto;  height: 100%;  display: flex;  align-items: center;  >span {    margin-right: 11px;    font-size: 14px;    font-weight: 400;    color: #4E5969;    line-height: 21px;  }  .smallpagination-pager {    display: flex;    align-items: center;    .el-icon {      width: 30px;      height: 30px;      font-size: 14px;      color: #4E5969;      cursor: pointer;      &:hover {background: rgb(247, 248, 250);color: #0082ff;      }    }    .forbid-pageturning {      opacity: 0.4;      cursor: not-allowed;      &:active {color: #4E5969;background: rgb(255, 255, 255);      }    }    >b {      margin: 0 5px;      font-size: 14px;      font-weight: 400;      color: #4E5969;    }  }}</style><style lang="less">.smallpagination {  .smallpagination-pager {    .el-input-number {      width: 40px;      margin-left: 5px;      span {display: none;      }      .el-input__wrapper {padding: 0;height: 30px;font-size: 14px;box-sizing: border-box;background: #f2f3f5;box-shadow: none !important;      }    }  }}</style>

使用简洁模式分页器组件代码如下：

<template>    <div>    	...<div>  <SmallPagination :total="total" :curPage="curPage" :pageSize="pageSize" @handlePageChange="handleCurrentChange">  </SmallPagination></div>    </div></template><script setup>import SmallPagination from "@/components/xxx/SmallPagination.vue";import { ref } from "vue";// 当前页const curPage = ref(1);// 每页条数const pageSize = ref(20);// 列表总数const total = ref(0);/* 当前页改变 */const handleCurrentChange = (val) => {  curPage.value = val;  ...};</script>

最终效果如下：
