本文实例为大家分享了Vue分页器组件的使用，供大家参考，具体内容如下
效果图如下：
鼠标悬浮时切换为箭头：
①创建自定义分页组件Pager.vue：预设主题色为@themeColor: #D93844; 每页展示10条数据，一次最多显示5个页码，支持输入页码跳转：
<template>
<div class="m-pager-wrap" v-if="totalCount">
<span class="u-text">共{{ totalPage }}页 / {{ totalCount }}条</span>
<span class="u-item txt" :class="{'disabled': currentPage===1}" @click="changePage(1)">首页</span>
<span class="u-item txt" :class="{'disabled': currentPage===1}" @click="changePage(currentPage - 1)">上一页</span>
<span
class="u-ellipsis"
ref="forward"
v-show="forwardMore"
@click="onForward"
@mouseenter="onEnterForward"
@mouseleave="onLeaveForward">···</span>
<span :class="['u-item', {'active': currentPage===num}]" v-for="num in pageList" :key="num" @click="changePage(num)">{{ num }}</span>
<span
class="u-ellipsis"
ref="backward"
v-show="backwardMore"
@click="onBackward"
@mouseenter="onEnterBackward"
@mouseleave="onLeaveBackward">···</span>
<span class="u-item txt" :class="{'disabled': currentPage===totalPage}" @click="changePage(currentPage + 1)">下一页</span>
<span class="u-item txt" :class="{'disabled': currentPage===totalPage}" @click="changePage(totalPage)">尾页</span>
<span class="u-jump-page">跳至<input type="text" v-model="jumpNumber"/>页</span>
<span class="u-item txt" @click="jumpPage(jumpNumber)">确定</span>
</div>
</template>
<script>
export default {
name: 'Pager',
data () {
return {
currentPage: this.pageNumber, // 当前页码
currentSize: this.pageSize, // 分页数
jumpNumber: '', // 跳转的页码
forwardMore: false, // 左箭头展示
backwardMore: false // 右箭头展示
}
},
props: {
pageNumber: { // 当前页面
type: Number,
default: 1
},
pageSize: { // 每页显示数量 [10条/页 20条/页 30条/页 40条/页]
type: Number,
default: 10
},
totalCount: { // 总条数
type: Number,
default: 0
},
pageListNum: { // 显示的页码数组长度
type: Number,
default: 5
}
},
computed: {
totalPage () { // 总页数
return Math.ceil(this.totalCount / this.currentSize) // 向上取整
},
pageList () { // 获取显示的页码数组
return this.dealPageList(this.currentPage)
}
},
watch: {
currentPage (to, from) {
// 通过更改当前页码，修改分页数据
this.$emit('changePage', { currentPage: to, currentSize: this.currentSize })
}
},
created () {
// 监听键盘Enter按键
document.onkeydown = (e) => {
const ev = e || window.event
if (ev && ev.keyCode === 13 && this.jumpNumber) {
this.jumpPage(this.jumpNumber)
}
}
},
methods: {
dealPageList (curPage) {
var resList = []
var offset = Math.floor(this.pageListNum / 2) // 向下取整
var pager = {
start: curPage - offset,
end: curPage + offset
}
if (pager.start < 1) {
pager.end = pager.end + (1 - pager.start)
pager.start = 1
}
if (pager.end > this.totalPage) {
pager.start = pager.start - (pager.end - this.totalPage)
pager.end = this.totalPage
}
if (pager.start < 1) {
pager.start = 1
}
if (pager.start > 1) {
this.forwardMore = true
} else {
this.forwardMore = false
}
if (pager.end < this.totalPage) {
this.backwardMore = true
} else {
this.backwardMore = false
}
// 生成要显示的页码数组
for (let i = pager.start; i <= pager.end; i++) {
resList.push(i)
}
return resList
},
onEnterForward () {
this.$refs.forward.innerHTML = '«'
},
onLeaveForward () {
this.$refs.forward.innerHTML = '···'
},
onEnterBackward () {
this.$refs.backward.innerHTML = '»'
},
onLeaveBackward () {
this.$refs.backward.innerHTML = '···'
},
onForward () {
this.currentPage = this.currentPage - this.pageListNum > 0 ? this.currentPage - this.pageListNum : 1
},
onBackward () {
this.currentPage = this.currentPage + this.pageListNum < this.totalPage ? this.currentPage + this.pageListNum : this.totalPage
},
jumpPage (jumpNum) {
if (Number(jumpNum)) {
if (Number(jumpNum) < 1) {
jumpNum = 1
}
if (Number(jumpNum) > this.totalPage) {
jumpNum = this.totalPage
}
this.changePage(Number(jumpNum))
}
this.jumpNumber = '' // 清空跳转输入框
},
changePage (pageNum) {
if (this.currentPage !== pageNum) { // 点击的页码不是当前页码
this.currentPage = pageNum
}
}
}
}
</script>
<style lang="less" scoped>
@themeColor: #D93844; // 自定义主题色
.m-pager-wrap {
height: 32px;
line-height: 30px;
font-size: 14px;
color: #888;
text-align: center;
.u-text {
margin-right: 5px;
}
.u-item {
margin-right: 5px;
min-width: 30px;
display: inline-block;
user-select: none; // 禁止选取文本
border: 1px solid #d9d9d9;
border-radius: 4px;
cursor: pointer;
&:hover {
.active();
}
}
.active {
color: #fff;
background: @themeColor;
border: 1px solid @themeColor;
}
.disabled {
color: rgba(0,0,0,.25);
&:hover {
cursor: not-allowed;
color: rgba(0,0,0,.25);
background: #fff;
border: 1px solid #d9d9d9;
}
}
.txt {
padding: 0 6px;
}
.u-ellipsis {
display: inline-block;
width: 12px;
padding: 0 8px;
margin-right: 5px;
cursor: pointer;
&:hover {
color: @themeColor;
}
}
.u-jump-page {
margin: 0 8px 0 3px;
input {
width: 32px;
height: 20px;
padding: 5px 8px;
margin: 0 5px;
border: 1px solid #d9d9d9;
border-radius: 4px;
text-align: center;
}
}
}
</style>
②在要使用的页面引入分页器：
<div class="m-page">
<Pager
@changePage="jumpPage"
:totalCount="totalCount"
:pageNumber="queryParams.p"
:pageSize="queryParams.pageSize" />
</div>
import Pager from '@/components/Pager'
components: {
Pager
}
totalCount: 0,
queryParams: {
pageSize: 10,
p: 1,
mod: 'search'
},
jumpPage (e) {
this.queryParams.p = e.currentPage
this.queryParams.pageSize = e.currentSize
this.getDataLists() // 调用接口获取列表数据
}
.m-page {
margin: 30px auto 60px;
}
