vue-element-admin点击侧边栏刷新当前页面
前言
在用 spa(单页面应用) 这种开发模式之前，用户每次点击侧边栏都会重新请求这个页面，用户渐渐养成了点击侧边栏当前路由来刷新 view 的习惯。但现在 spa 就不一样了，用户点击当前高亮的路由并不会刷新 view，因为 vue-router 会拦截你的路由，它判断你的 url 并没有任何变化，所以它不会触发任何钩子或者是 view 的变化。(参考文章：vue-elemnt-admin文档)
一、刷新整个路由页面
利用$nextTick和v-if配合在点击后刷新当前路由
app.vue文件中进行相应的配置，配置v-if和刷新方法
<template>
<div id="app">
<router-view v-if="isRouterAlive" />
</div>
</template>
<script>
export default {
name: 'App',
provide() {
return {
reload: this.reload
};
},
data() {
return {
isRouterAlive: true
};
},
methods: {
reload() {
console.log('触发reload函数')
this.isRouterAlive = false;
this.$nextTick(function () {
this.isRouterAlive = true;
});
}
}
}
</script>
然后在src/layout/components/sidebar/index.vue文件夹下我们先接收函数，然后根据路由地址检测是否有发生变化，如果发生变化就调用reload刷新函数。
<template>
<div :class="{ 'has-logo': showLogo }">
<logo v-if="showLogo" :collapse="isCollapse" />
<el-scrollbar wrap-class="scrollbar-wrapper">
<el-menu :default-active="activeMenu" :collapse="isCollapse" :background-color="variables.menuBg"
:text-color="variables.menuText" :unique-opened="false" :active-text-color="variables.menuActiveText"
:collapse-transition="false" mode="vertical" @select="handleSelect">
<sidebar-item v-for="route in routes" :key="route.path" :item="route" :base-path="route.path" />
</el-menu>
</el-scrollbar>
</div>
</template>
<script>
import {
mapGetters } from 'vuex'
import Logo from './Logo'
import SidebarItem from './SidebarItem'
import variables from '@/styles/variables.scss'
export default {
inject: ['reload'],
components: {
SidebarItem, Logo },
computed: {
...mapGetters([
'sidebar'
]),
routes() {
return this.$router.options.routes
},
activeMenu() {
const route = this.$route
const {
meta, path } = route
// if set path, the sidebar will highlight the path you set
if (meta.activeMenu) {
return meta.activeMenu
}
return path
},
showLogo() {
return this.$store.state.settings.sidebarLogo
},
variables() {
return variables
},
isCollapse() {
return !this.sidebar.opened
}
},
methods: {
handleSelect(index) {
console.log(index)
const route = this.$route
const {
path } = route
if (index === path) {
this.reload()
}
}
}
}
</script>
二、只刷新嵌套路由页面
逻辑方面是大致一样的只需要将reload和v-if判断更改到嵌套路由vue文件就可以了
嵌套路由的main文件路径为src/layout/index.vue
<template>
<div :class="classObj" class="app-wrapper">
<div v-if="device === 'mobile' && sidebar.opened" class="drawer-bg" @click="handleClickOutside" />
<sidebar class="sidebar-container" />
<div class="main-container">
<div :class="{ 'fixed-header': fixedHeader }">
<navbar />
</div>
<app-main v-if="isRouterAlive" />
</div>
</div>
</template>
<script>
import {
Navbar, Sidebar, AppMain } from './components'
import ResizeMixin from './mixin/ResizeHandler'
export default {
name: 'Layout',
components: {
Navbar,
Sidebar,
AppMain
},
provide() {
return {
reloadMain: this.reloadMain
};
},
data() {
return {
isRouterAlive: true
};
},
mixins: [ResizeMixin],
computed: {
sidebar() {
return this.$store.state.app.sidebar
},
device() {
return this.$store.state.app.device
},
fixedHeader() {
return this.$store.state.settings.fixedHeader
},
classObj() {
return {
hideSidebar: !this.sidebar.opened,
openSidebar: this.sidebar.opened,
withoutAnimation: this.sidebar.withoutAnimation,
mobile: this.device === 'mobile'
}
}
},
methods: {
handleClickOutside() {
this.$store.dispatch('app/closeSideBar', {
withoutAnimation: false })
},
reloadMain() {
this.isRouterAlive = false;
this.$nextTick(function () {
this.isRouterAlive = true;
});
}
}
}
</script>
<style lang="scss" scoped>
@import "~@/styles/mixin.scss";
@import "~@/styles/variables.scss";
.app-wrapper {
@include clearfix;
position: relative;
height: 100%;
width: 100%;
&.mobile.openSidebar {
position: fixed;
top: 0;
}
}
.drawer-bg {
background: #000;
opacity: 0.3;
width: 100%;
top: 0;
height: 100%;
position: absolute;
z-index: 999;
}
.fixed-header {
position: fixed;
top: 0;
right: 0;
z-index: 9;
width: calc(100% - #{
$sideBarWidth});
transition: width 0.28s;
}
.hideSidebar .fixed-header {
width: calc(100% - 54px)
}
.mobile .fixed-header {
width: 100%;
}
</style>
