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:
