el-nav.vue:
<template>
<el-menu theme="dark" default-active="1" class="el-menu-demo" mode="horizontal" :router="true">
<el-menu-item index="/elindex/hot">處理中心</el-menu-item>
<el-submenu index="2">
<template slot="title">我的工作臺< /template>
<el-menu-item index="2-1">選項1</el-menu-item>
<el-menu-item index="2-2">選項2</el-menu-item>
<el-menu-item index="2-3">選項3</el-menu-item>
</el-submenu>
<el-menu-item index="3">訂單管理</el-menu-item >
</el-menu>
</template>
el-index:
<template>
<div>
<el-row>
<el-col :span="24"><div class="grid-content bg-purple-dark"></div></el-col>
<!--使用元件-->
<elnav></elnav>
</el-row >
<!--巢狀路由-->
<router-view></router-view>
</div>
</template>
<script>
// 引入elmenetui的導航元件
import elnav from "./el-nav.vue";
export default {
//載入元件
components:{elnav}
}
</script>
el-hot.vue:
<template>
<div>
<el-row v-for="hotNews in this.$store.state.ele.hot" justify="start" :gutter="2" align="middle">
<el-col :span="6">
<div class="grid-content bg-purple-dark hotimg">
<img :src="hotNews.image"/>
</div>
</el-col>
<el-col :span="18">
<div class="grid-content bg-purple-dark hotcontent">
<h2>{{hotNews.title}}</h2>
<p>{{hotNews.desc}}</p>
</div>
</el-col>
</el-row>
</div>
</template>
<script>
export default{
mounted(){
this.$store.dispatch("getHot");
},
data(){
return {msg:"hello vue"}
}
}
</script>
eleModule.js:
import Vue from "vue";
export default{
state:{
hot:[] //用來裝請求回來的資料
},
mutations:{
//寫個方法給hot陣列設定資料
setHot(state, data){
state.hot = data;
}
},
actions:{
//寫個方法,做http請求
getHot(content){
//loading效果
let loading = Vue.prototype.$loading({text:"玩命載入中..."});
Vue.http.get("http://localhost/eleui.php",{},{emulateJSON:true})
.then(
function (res) { //請求成功的回撥函式
//先結束loading效果
loading.close();
//呼叫設定hot資料的方法,把請求成功的資料給hot陣列
content.commit("setHot",res.body);
},function(){}
);
}
}
}
入口檔案jssrc/index.js:
import Vue from "vue";
import pagenav from "./../components/page-nav.vue";
import newsdetail from "./../components/news-detail.vue";
// 引入
import validate from "./../components/validate";
// 使用
Vue.use(validate);
import VueRouter from 'vue-router';
Vue.use(VueRouter); // 全域性使用外掛
import VueResource from 'vue-resource';
Vue.use(VueResource);
import UserModule from "./../store/modules/UserModule";
import NewsModule from "./../store/modules/NewsModule";
import EleModule from "./../store/modules/eleModule";
import Vuex from 'vuex';
Vue.use(Vuex);
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-default/index.css';
Vue.use(ElementUI);
import eltable from "./../components/el-table.vue";
import elindex from "./../components/elmentui/el-index.vue";
import elhot from "./../components/elmentui/el-hot.vue";
const vuex_store = new Vuex.Store({
modules:{
users:UserModule,
news:NewsModule,
ele:EleModule
}
})
const userlogin = resolve => {
// 成功之後的回撥
resolve(require("./../components/user-login.vue")); // 這就是非同步載入的方式
}
const newslist = resolve => {
// 成功之後的回撥
resolve(require("./../components/news-list.vue")); // 這就是非同步載入的方式
}
const routerConfig = new VueRouter({
routes: [
{ path: '/', component: userlogin},
{ path: '/news', component: newslist, name:"newslist"},
{ path: '/news/:newsid', component: newsdetail, name:"newsdetail"},
{ path: '/login', component: userlogin,name:"userlogin" },
{ path: '/eltable', component: eltable,name:"eltable" },
{ path: '/elindex', component: elindex,name:"elindex", children:[
{path:"hot",component:elhot,name:"elhot"}
]}
]
})
// 全域性元件,不加入路由管理
Vue.component("page-nav",pagenav);
let myvue = new Vue({
el:".container",
store:vuex_store, //注入到vue
router:routerConfig,
});
程式碼分析
1、ele-nav導航元件 是巢狀在 ele-index元件裡的,ele-index里加載導航元件
import elnav from "./el-nav.vue";
components:{elnav}
<!--使用元件-->
<elnav></elnav>
2、建立了eleModule模組之後,需要在入庫檔案里加載
//引入
import EleModule from "./../store/modules/eleModule";
// 使用
const vuex_store = new Vuex.Store({
modules:{
users:UserModule,
news:NewsModule,
ele:EleModule
}
})
3、給ele配置路由
// 引入
import elindex from "./../components/elmentui/el-index.vue";
import elhot from "./../components/elmentui/el-hot.vue";
// 配置
const routerConfig = new VueRouter({
routes: [
{ path: '/', component: userlogin},
{ path: '/news', component: newslist, name:"newslist"},
{ path: '/news/:newsid', component: newsdetail, name:"newsdetail"},
{ path: '/login', component: userlogin,name:"userlogin" },
{ path: '/eltable', component: eltable,name:"eltable" },
{ path: '/elindex', component: elindex,name:"elindex", children:[
{path:"hot",component:elhot,name:"elhot"}
]}
]
})
這裡用到了巢狀路由:
{ path: '/elindex', component: elindex,name:"elindex", children:[
{path:"hot",component:elhot,name:"elhot"}
]}
巢狀路由在元件裡也需要配合:
<!--巢狀路由-->
<router-view></router-view>
/elindex/hot
效果演示
php程式碼:
<?php
// 指定允許其他域名訪問
header('Access-Control-Allow-Origin:*');
// 響應型別
header('Access-Control-Allow-Methods:GET');
header('Access-Control-Allow-Headers:x-requested-with,content-type');
//測試資料
header("content-type:application/json"); //這句話TM很重要哦,否則到前端獲取時 只是普通字串,不會自動識別
