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 class="smallpagination">
<!-- 总数统计 -->
<span>{{ '共' + total + '条' }}</span>
<!-- 翻页 -->
<div class="smallpagination-pager">
<!-- 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;
});
const handlePageChange = (e) => {
if (pageTotal.value <= 1) {
return;
}
em('handlePageChange', e);
};
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 class="xxx-list">
...
<div class="list-bottom-common-page">
<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);
const handleCurrentChange = (val) => {
curPage.value = val;
...
};
</script>
最终效果如下:
