不废话，先上组件文件pages.vue:
<template>
<div class="pages-box" v-if="pageTotal > 0">
<ul class="pages">
<li class="pages-prev">
<a v-if="pageNow != 1" href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="prevClick">上一页</a>
</li>
<!--如果只有一页就不显示固定的第一个分页按钮了,避免重复-->
<template v-if="pageTotal > 1">
<li v-for="i in pageBegin" class="pages-li" :class="{active:i == pageNow}">
<span v-if="i == pageNow" v-text="i"></span>
<a v-else href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" @click="pageClick" v-text="i"></a>
</li>
</template>
<li v-if="ellipsis[0] > slider">
<span>...</span>
</li>
<li v-for="i in pageMiddle" class="pages-li" :class="{active:i == pageNow}">

使用方法：
在需要分页的地方使用分页组件标签，比如这里的order.vue：
<!--分页组件--> <pages :now="page" :total="totalPage" v-if="totalPage > 0"></pages>
在data中设置当前页和总页面的默认值
data(){
return {
totalPage:1,
page:1,
}
},
考虑一下我们希望我们点击页数按钮后发生什么
首先，点击某页数时路由会改变页数，从路由获取当前页
this.page = this.$route.params.page;
接着，我们希望有一个getorderfromServer方法将当前页数发送给服务器，再将返回的数据更新在页面上
getorderfromServer({
currentPage:this.page
})
最后调用的方法：
methods: {
// 查询全部订单
getorderfromServer(){
this.loading = true;
this.page = this.$route.params.page;
getorderfromServer({
currentPage: this.page,
orderTimeStart:this.orderTimeStart,
orderTimeEnd:this.orderTimeEnd,
serviceName:this.serviceName,
shopName:this.shopName,
status: this.status
}).then(({code, data}) => {
if (code == 200) {
this.Orderlist = data.list;
this.totalPage = data.totalPage;
}
this.loading = false;
}).catch(err => {
this.tip('服务内部错误', 'error');
this.Orderlist = {};
this.loading = false;
});
},
}
注意通过路由对方法作出响应，每次路由改变都调用此方法以更新页面
watch: {
$route: 'getorderfromServer'
}
还要对路由信息进行改造，让每一页（尤其是第一页）都有路由页数信息，可以对第一页进行重定向以达到目的：
{
path: 'order',
redirect: 'order/page/1',
},
{
path: 'order/page/:page',
component(resolve){
require.ensure([], function (require) {
resolve(require('../modules/personal/order/myorder.vue'));
}, 'modules/personal')
},
name:'order',
meta: {
login: 'none'
}
},
