使用vue编写的分页器组件，支持输入页码跳转，效果如果：

1、点击前五页：

2、点击中间部分页面

3、点击第一页，上一页按钮失效，点击最后一页，下一页按钮失效

组件调用：

//html调用 参数:pageSize(总页数);pageNo(当前页)
<pager :pageSize="pageSize" v-model="pageNo" @on-jump="jump"></pager>

//组件引入
import pager from '../../component/pager/pager.vue'

//组件调用声明
components:{ pager}

//参数
data(){
    return {
        pageSize: 30,
        pageNo: 2
    }
}

//接收跳转事件
methods:{
    jump(id){
        console.log(id)
    },
}

组件编写

pager.vue：

<template>
    <div class="pager-wrapper" ref="pager">
        <div class="pager-box">
            <a class="pager-prev" :class="{'pager-disabled':prevDisable}" href="javascript:;" @click="jumpPrev()">上一页</a>
            <template v-for="i in pageSize">
                <span v-if="i==pageNo" class="pager-curr">
                    <em class="pager-em"></em><em>{{i}}</em>
                </span>
                <a v-else-if="pageNo<5&&(i)<6" href="javascript:;" @click="jump(i)">
                    {{i}}
                </a>
                <a v-else-if="pageSize<7||i==1||i==pageSize||(pageNo-2<=i&&i<=pageNo+2)" href="javascript:;" @click="jump(i)">
                    {{i}}
                </a>
                <template v-else>
                    <span v-if="pageNo<5&&i==6" class="pager-spr">…</span>
                    <span v-if="pageNo==4&&i==7" class="pager-spr">…</span>

                </template>
            </template>
            <a class="pager-next" :class="{'pager-disabled':nextDisable}" href="javascript:;" @click="jumpNext()">下一页</a>
        </div>
        <div class="pager-input">
