在后台管理系统中当点击某一按钮时,页面发生跳转(路由发生跳转,跳转到与按钮对应的页面),在跳转的同时在侧边栏中打开与之对应模块的菜单项
1.点击按钮跳转到/pay/PayIndex页面
2.在后台管理系统中侧边栏使用的是element ui 中的NavMenu导航菜单组件,在后台管理系统 src/layout/components/Sidebar/index中代码如下:
<template>
<div
:class="{ 'has-logo': showLogo }"
:style="{
backgroundColor:settings.sideTheme === 'theme-dark'? variables.menuBackground : variables.menuLightBackground,}">
<logo v-if="showLogo" :collapse="isCollapse" />
<el-scrollbar :class="settings.sideTheme" wrap-class="scrollbar-wrapper">
<el-menu
:default-active="activeMenu"
:collapse="isCollapse"
:background-color=" settings.sideTheme === 'theme-dark' ? variables.menuBackground : variables.menuLightBackground"
:text-color="settings.sideTheme === 'theme-dark' ? variables.menuColor: variables.menuLightColor"
:unique-opened="true"
:active-text-color="settings.theme"
:collapse-transition="false"
mode="vertical"
:default-openeds="openeds"
>
<sidebar-item
v-for="(route, index) in sidebarRouters"
:key="route.path + index"
:item="route"
:base-path="route.path"
/>
</el-menu>
<!-- :index="route.path" -->
</el-scrollbar>
</div>
</template>
<script>
import { mapGetters, mapState } from "vuex";
import Logo from "./Logo";
import SidebarItem from "./SidebarItem";
import variables from "@/assets/styles/variables.scss";
export default {
components: { SidebarItem, Logo },
data() {
return {
openeds: [],
};
},
computed: {
...mapState(["settings"]),
...mapGetters(["sidebarRouters", "sidebar"]),
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;
},
},
//组件路由发生变化,打开与组件对应模块的菜单项
watch: {
"$route.path": function (newVal) {
// 先清空数组,确保数组中只存放一个路由信息
if (this.openeds.length > 0) {
this.openeds = [];
}
// newVal为路由 /pay/PayIndex
let str = newVal.split("/");
// url为/pay 打开/pay所对应的菜单项
let url = "/" + str[1];
this.openeds.push(url);
},
},
};
</script>
可通过default-openeds指定想要打开的菜单项(也可设置默认打开的菜单项 如 :default-openeds="[/system/user]")
通过监听路由的变化,打开与要跳转的组件页面相对应的菜单项,把变化的路由存放到openeds数组中,实现路由跳转动态的打开与之对应的菜单项
