前言
本來想寫個新手系列教程..發現這種東西一搜尋一大把;
那就寫點實戰類的吧;
這篇文章你能學點什麼?
當然是一些常見內建指令的用法,元件過渡,遍歷的思路等等
效果圖
實現思路
- 過渡用css –
- 遍歷迴圈判斷(比對路由,點選的項名等)
- 增加標記位來預設展開重新整理頁面當前所在項
- 儘量減少DOM的改動,能用
v-show的區域絕不用v-if - 自定義選單JSON儘量格式簡潔,沒有一大坨標記位這些干擾物(越簡單越方便後期)
程式碼
- 選單
menuList.js
export const MENULIST = [ {
menuName: "客戶管理", menuIcon: "fz-ad-icon-test", menuSubLink: [ {
menuName: "廣告主", menuUrl: "/customer/adhost"
}, {
menuName: "渠道", menuUrl: "/customer/channel"
} ]
}, {
menuName: "廣告管理", menuIcon: "fz-ad-guanggao", menuSubLink: [ {
menuName: "廣告新增", menuUrl: "/ad/add"
}, {
menuName: "廣告稽核", menuUrl: "/ad/check"
} ]
}, {
menuName: "投放管理", menuIcon: "fz-ad-toufang", menuSubLink: [ {
menuName: "廣告位", menuUrl: "/puton/area"
}, {
menuName: "廣告規格", menuUrl: "/puton/regular"
} ]
}, {
menuName: "資料統計", menuIcon: "fz-ad-statistics", menuSubLink: [ {
menuName: "廣告主", menuUrl: "/status/adhost"
}, {
menuName: "渠道", menuUrl: "/status/channel"
} ]
}, {
menuName: "管理者", menuIcon: "fz-ad-guanli", menuUrl: "/manager"
}, {
menuName: "操作日誌", menuIcon: "fz-ad-rizhi", menuUrl: "/logger"
}];

複製程式碼總結
實際上這貨就是把adminlte的風格用vue實現了…
還有變形金剛版本,,整個響應涉及幾個到元件間的通訊;
就不把全部程式碼丟出來了,一大坨…
效果是這樣的
