獲取全部的數據庫列表javascript
點擊某一個數據庫列表的時候,右側分頁展現數據css
點擊右側某一條數據的時候,現實數據詳情html
前段開發沒有工程化(webpack)vue
主要功能耦合,列表,詳情,(檢索,重構的是爲了加功能方便)java
左側的數據庫連接是直接跳頁的,分頁的連接是跳頁的,右側點擊的詳情頁倒是vue-resource加載的webpack
代碼結構混亂,以前爲了快速實現功能。全部代碼寫在一個文件上。難讀。web
前段模塊化開發,用webpack,參考我vue-router
利用compoment組件化,組件化原則:組件只須要告訴別本身什麼狀態,狀態自治。組件不要去要求別的組件作什麼數據庫
由於用vue就要體驗spa,根據頁面功能,利用vue-router配置頁面路由編程
由於功能少,因此就略過了 前段模塊化開發,用webpack,參考我這篇
由於以前全部代碼都是寫在一個文件的,如今爲了代碼清晰易讀易擴展,將前段js代碼拆分爲三個文件
compoments.js
對應抽離的組件
router.js
配置路由文件
show_database.js
vue實例
itemsNumber
--顯示數據條數
databaseLists
--左側數據庫列表
itemsLists
--右側數據列表
pagination
--底部的分頁
itemDetail
--詳情頁
listCompoment
--vue-router用到的組件包含itemsLists 和 pagination
/core/:core
和詳情/detail/:id
兩個路由,之後還有個檢索頁的路由由於數據列表和詳情的數據是獨立接口獲取的,這樣分符合功能
(想了好久,沒想到更好地想法,第一次接觸vue-router,一邊文檔,一邊coding)
專一vue開發的老同窗,一個電話什麼疑難雜症全解決
vue-router文檔中的一些功能只有在新版本中才有效,一開始怕3.0太冒進了,就選了個2.0,一段時間後發現一些功能死活不成功如:router.push
等。細看文檔。原來是新版本特有的。因此之後看選版本要對着文檔選,實在不行就選擇最新的大版本,如3.0
vue-router中如何給組件傳props?細看文檔向路由組件傳遞 props搞定
vue-router中如何監聽路由組件中的事件?由於路由組件listCompoment獲取到數據庫列表中須要向外發送找到的數據
//發送找到的數據 this.$emit('num-found',this.numFound);
我記得在官方文檔經過事件向父級組件發送消息
v-on:num-found
在組件上監聽是官方文檔的作法。可是路由組件怎麼綁定事件呢?$emit的事件是能夠用$on來接受的?;然而試了不能夠;
折騰了好久,直接電話老同窗,得知能夠直接在router-view中綁定事件監聽
router-view(v-on:num-found='getnumFound')
若是是觸發事件是包含大寫的卻不能成功
this.$emit(:'numFound',this.numFound);
v-on:numFound
。。。。。。未完待續

// 0. 若是使用模塊化機制編程,導入Vue和VueRouter,要調用 Vue.use(VueRouter) // 1. 定義(路由)組件。 // 能夠從其餘文件 import 進來 // var Foo = { template: '<div>foo-><router-link to="/bar">Go to Bar</router-link></div>' } // var Bar = { template: '<div>bar-><router-link to="/foo">Go to Foo</router-link></div>' } // 2. 定義路由 // 每一個路由應該映射一個組件。 其中"component" 能夠是 // 經過 Vue.extend() 建立的組件構造器, // 或者,只是一個組件配置對象。 // 咱們晚點再討論嵌套路由。 var routes = [ { path: '/core/:core', component: listCompoment, name:'core', props:function (route) { // console.log(route,'-----') // routes.query.rows = route.params.rows; // routes.query.start = route.params.start; return { core:route.params.core, rows:route.params.rows, start:route.params.start } } } // , // { // path: '/detail/:tableId/:itemId', // component:itemDetail, // name:'detail', // props:{ // isShowDetail:this.isShowDetail, // tableData:this.tableData, // backFn:this.closeDetail // } // } ] // 3. 建立 router 實例,而後傳 `routes` 配置 // 你還能夠傳別的配置參數, 不過先這麼簡單着吧。 var router = new VueRouter({ routes: routes, mode: 'history', base:'/show_database/' // routes // (縮寫)至關於 routes: routes }) // 4. 建立和掛載根實例。 // 記得要經過 router 配置參數注入路由, // 從而讓整個應用都有路由功能 // var app = new Vue({ // }).$mount('#app') // 如今,應用已經啓動了!
