不廢話，先上組件文件pages.vue:

<!--如果只有一頁就不顯示固定的第一個分頁按鈕了,避免重復-->

使用方法：
在需要分頁的地方使用分頁組件標簽，比如這里的order.vue：
<!--分頁組件--> <pages :now="page" :total="totalPage" v-if="totalPage > 0"></pages>
在data中設置當前頁和總頁面的默認值
data(){
return {
totalPage:1,
page:1,
}
},
考慮一下我們希望我們點擊頁數按鈕后發生什么
首先，點擊某頁數時路由會改變頁數，從路由獲取當前頁
this.page = this.$route.params.page;
接著，我們希望有一個getorderfromServer方法將當前頁數發送給服務器，再將返回的數據更新在頁面上
getorderfromServer({
currentPage:this.page
})
最后調用的方法：
methods: {
// 查詢全部訂單
getorderfromServer(){
this.loading = true;
this.page = this.$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('服務內部錯誤', 'error');
this.Orderlist = {};
this.loading = false;
});
},
}
注意通過路由對方法作出響應，每次路由改變都調用此方法以更新頁面
watch: {
$route: 'getorderfromServer'
}
還要對路由信息進行改造，讓每一頁（尤其是第一頁）都有路由頁數信息，可以對第一頁進行重定向以達到目的：
{
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'
}
},
