Vue分页导航_vue分页组件

大家好，又见面了，我是你们的朋友全栈君。

Vue分页导航原文链接：https://www.cnblogs.com/vivaxiaonan/p/9987985.html

这里我用的是脚手架，粘 Viva_nan 大佬的代码封装了一个.vue组件。

实现效果如下：

封装组件 newCom.vue 代码:

代码语言：javascript复制

<template>
<div class="wrapper">
<nav class="zpagenav">
<ul class="page-ul">
<li :key="index" v-for="(item,index) in pageList" :class ="item.class" @click.stop="setPage(item)" v-html="item.html">
</li>
</ul>
<span class="total">共 {
{total}} 条</span>
</nav>
</div>
</template>
<script>
export default {
name: '',
components: {},
props: {
prevHtml: String,
nextHtml: String,
page: Number,
total: Number,
pageSize: Number,
maxPage: Number
},
data() {
return {
}
},
watch: {},
computed: {
pageList() {
var _this = this,
pageList = [];
let pageCount = Math.ceil(_this.total / _this.pageSize);
let page = _this.page;
let prevHtml = _this.prevHtml ? _this.prevHtml : '&lt;';
let nextHtml = _this.nextHtml ? _this.nextHtml : '&gt;';
let maxPage = _this.maxPage ? _this.maxPage : 9;
let hasPrev = page > 1;
let hasNext = page < pageCount;
//上一页
pageList.push({
class: hasPrev ? '' : 'disabled',
page: hasPrev ? page - 1 : page,
html: prevHtml
});
//首页
pageList.push({
class: page == 1 ? 'active' : '',
page: 1,
html: 1
});
var p0 = Math.floor(maxPage / 2);
var p1 = 1   2   p0; //首页 省略至少2个页码 中间页面数的一半
var start, end;
if(page >= p1) {
start = page - p0;
//前置省略号
pageList.push({
class: 'dot',
page: page,
html: '...'
});
} else {
start = 2;
}
var p2 = page   p0;
if(p2 < pageCount) {
end = p2;
} else {
end = pageCount - 1;
}
//页码列表
for(let i = start; i <= end; i  ) {
pageList.push({
class: page == i ? 'active' : '',
page: i,
html: i
});
}
if(end < pageCount - 1) {
//后置省略号
pageList.push({
class: 'dot',
page: page,
html: '...'
});
}
//尾页
if(pageCount > 1) {
pageList.push({
class: page == pageCount ? 'active' : '',
page: pageCount,
html: pageCount
});
}
//下一页
pageList.push({
class: hasNext ? '' : 'disabled',
page: hasNext ? page   1 : page,
html: nextHtml
});
return pageList;
}
},
methods: {
setPage(item) {
if(item.class == '') {
this.$emit('pagehandler', item.page);
}
}
},
created() {},
mounted() {}
}
</script>
<style scoped>
.wrapper{padding: 0; margin: 0;}
.zpagenav {
text-align: center;
-webkit-user-select: none;
}
.zpagenav {
font-family: arial;
color: #48576a;
}
.zpagenav ul {
display: inline-block;
margin: 20px 20px;
padding: 0;
}
.zpagenav ul li {
display: inline-block;
margin: 0;
padding: 0 4px;
border: 1px solid #d1dbe5;
border-right: 0;
background: #fff;
font-size: 13px;
min-width: 28px;
height: 28px;
line-height: 28px;
cursor: pointer;
box-sizing: border-box;
text-align: center;
}
.zpagenav ul li:last-child {
border-right: 1px solid #d1dbe5;
}
.zpagenav ul li:hover {
color: #20a0ff;
}
.zpagenav ul li.active {
border-color: #20a0ff;
background-color: #20a0ff;
color: #fff;
cursor: default;
}
.zpagenav ul li.active:hover {
color: #fff;
}
.zpagenav ul li.disabled {
cursor: not-allowed;
color: #e4e4e4;
}
.zpagenav ul li.dot {
cursor: default;
}
</style>

使用封装组件 new.vue 代码：

代码语言：javascript复制

<template>
<div class="wrapper">
<new-com :page="page" :page-size="pageSize" :total="total" 
:max-page="maxPage"  @pagehandler="pageHandler">
</new-com>
</div>
</template>
<script>
import newCom from '@/views/new/newCom.vue'
export default {
name: '',
components: {
newCom
},
props: {},
data() {
return {
page: 1,  //显示的是哪一页
pageSize: 10, //每一页显示的数据条数
total: 150, //记录总数
maxPage:3  //最大页数
}
},
watch: {},
computed: {},
methods: {
//pagehandler方法 跳转到page页
pageHandler(page) {
//here you can do custom state update
this.page = page;
console.log(page)
}
},
created() {
//created  表示页面加载完毕，立即执行
this.pageHandler(1);
},
mounted() {}
}
</script>
<style scoped>
.wrapper{padding: 0; margin: 0;}
</style>
