Appearance
在设置面板中，除了主题颜色的选择设置，还可以添加其他全局配置选项，如 tagsView 导航栏，Logo 的显示隐藏配置等。
Settings 的 Pinia 配置
在 src/stores/settings.ts 中添加要持久存储的全局配置项，这里是 tagsView 和 sidebarLogo，代码如下：
typescript
//src/stores/settings.ts
import variables from "@/style/variables.module.scss";
// 定义一个名为 "setting" 的 Vuex 存储，用于管理应用的设置
export const useSettingStore = defineStore(
"setting",
() => {
// 如果选择的是同样的主题颜色，就不更改，节省
const settings = reactive({
theme: variables.theme, //当前选择的颜色
originalTheme: "", //正在应用的颜色
tagsView: true,
sidebarLogo: true,
});
type ISetting = typeof settings;
// 定义一个方法来更改设置
const changeSetting = <T extends keyof ISetting>({
key,
value,
}: {
key: T;
value: ISetting[T];
}) => {
settings[key] = value;
};
return { changeSetting, settings };
},
{
persist: {
storage: sessionStorage, // 使用 sessionStorage 作为持久化存储
pick: ["settings.theme", "settings.tagsView", "settings.sidebarLogo"], // 仅持久化 theme、tagsView、sidebarLogo 三个设置
},
}
);Settings 组件
在 src/layout/components/Settings/index.vue 中增加要添加的全局配置内容，代码如下：
html
//src/layout/components/Settings/index.vue
<template>
<div class="drawer-item">
<span>主题色</span>
<theme-picker></theme-picker>
</div>
<div class="drawer-item">
<span>是否展示TagsView</span>
<el-switch v-model="isShowTagsView"></el-switch>
</div>
<div class="drawer-item">
<span>是否展示Logo</span>
<el-switch v-model="isShowLogo"></el-switch>
</div>
</template>
<script lang="ts" setup>
import { useSettingStore } from "@/stores/settings";
const settingsStore = useSettingStore();
const sidebarLogo = computed(() => settingsStore.settings.sidebarLogo);
const tagsView = computed(() => settingsStore.settings.tagsView);
const isShowTagsView = computed({
get() {
return tagsView.value;
},
set(val: boolean) {
settingsStore.changeSetting({ key: "tagsView", value: val });
},
});
const isShowLogo = computed({
get() {
return sidebarLogo.value;
},
set(val: boolean) {
settingsStore.changeSetting({ key: "sidebarLogo", value: val });
},
});
</script>添加页面控制
3.1 TagsView 配置
3.1.1 导出样式高度
在 src/style/variables.module.scss 中将需要参与高度计算的样式变量导出（navBarHeight、tagsViewHeight）并在 src/style/variables.module.scss.d.ts 中定义类型，代码如下：
scss
//src/style/variables.module.scss
$sideBarWidth: 210px;
$navBarHeight: 50px;
$tagsViewHeight: 34px;
// 导航颜色
$menuText: #bfcbd9;
// 导航激活的颜色
$menuActiveText: #409eff;
// 菜单背景色
$menuBg: #304156;
$theme: #409eff;
:export {
menuText: $menuText;
menuActiveText: $menuActiveText;
menuBg: $menuBg;
theme: $theme;
navBarHeight: $navBarHeight;
tagsViewHeight: $tagsViewHeight;
}typescript
//src/style/variables.module.scss.d.ts
interface IVaraibles {
menuText: string;
menuActiveText: string;
menuBg: string;
theme: string;
navBarHeight: string;
tagsViewHeight: string;
}
export const varaibles: IVaraibles;
export default varaibles;3.1.2 页面修改
在 src/layout/index.vue 中添加选项控制属性，并根据 tagsView 的显示隐藏状态，动态计算页面高度，代码如下：
html
//src/layout/index.vue
<template>
<div class="app-wrapper">
<div class="sidebar-container">
<sidebar></sidebar>
</div>
<div class="main-container">
<div class="header">
<!-- 上边包含收缩的导航条 -->
<navbar @showSetting="openSetting"></navbar>
<tags-view v-if="isShowTagsView"></tags-view>
</div>
<div class="app-main">
<app-main></app-main>
</div>
</div>
<right-panel v-model="setting" title="设置">
<!-- 设置功能 -->
<Settings></Settings>
</right-panel>
</div>
</template>
<script lang="ts" setup>
import { useSettingStore } from "@/stores/settings";
import variables from "@/style/variables.module.scss";
const setting = ref(false);
const openSetting = () => {
setting.value = true;
};
const settingsStore = useSettingStore();
const isShowTagsView = computed(() => settingsStore.settings.tagsView);
const outerHeight = computed(() => {
return (
(isShowTagsView.value
? parseInt(variables.navBarHeight) + parseInt(variables.tagsViewHeight)
: parseInt(variables.navBarHeight)) + "px"
);
});
</script>
<style lang="scss" scoped>
.app-wrapper {
@apply flex w-full h-full;
.app-main {
@apply overflow-hidden pos-relative;
min-height: calc(100vh - v-bind(outerHeight));
}
.sidebar-container {
// 跨组件设置样式
@apply bg-[var(--menu-bg)];
:deep(.sidebar-container-menu:not(.el-menu--collapse)) {
@apply w-[var(--sidebar-width)];
}
}
.main-container {
@apply flex flex-col flex-1 overflow-hidden;
}
}
</style>3.2 Logo 配置
3.2.1 Logo 组件开发
开发 Logo 组件，在 src/layout/components/Sidebar 下新建 logo.vue，代码如下：
html
//src/layout/components/Sidebar/logo.vue
<template>
<div class="sidebar-logo-container" :class="{ collapse }">
<transition name="logo-fade">
<router-link to="/" :key="collapse ? 'a' : 'b'" class="sidebar-logo">
<img :src="logo" alt="" />
<h1 v-if="!collapse" class="sidebar-logo-title">Vue admin</h1>
</router-link>
</transition>
</div>
</template>
<script lang="ts" setup>
import logo from "@/assets/vue.svg";
defineProps({
collapse: {
type: Boolean,
},
});
</script>
<style scoped lang="scss">
.sidebar-logo {
@apply w-full h-60px lead-60px flex items-center justify-center;
}
.sidebar-logo-title {
@apply inline-block text-20px text-white mx-10px;
}
.logo-fade-enter-from,
.logo-fade-leave-to {
@apply opacity-0;
}
.logo-fade-enter-active {
@apply transition-opacity duration-150;
}
</style>3.2.2 页面引入
在 src/layout/components/Sidebar/index.vue 中引入 Logo 组件，代码如下：
html
//src/layout/components/Sidebar/index.vue
<template>
<div>
<logo v-if="sidebarLogo" :collapse="sidebar.opened"></logo>
<el-menu
class="sidebar-container-menu"
router
:default-active="defaultActive"
:background-color="varaibles.menuBg"
:text-color="varaibles.menuText"
:active-text-color="theme"
:collapse="sidebar.opened"
>
<sidebar-item
v-for="route in routes"
:key="route.path"
:item="route"
:base-path="route.path"
/>
<!-- 增加父路径，用于el-menu-item渲染的时候拼接 -->
</el-menu>
</div>
<!-- :collapse="true" -->
</template>
<script lang="ts" setup>
import { useAppStore } from "@/stores/app";
import varaibles from "@/style/variables.module.scss";
import { routes } from "@/router";
import { useSettingStore } from "@/stores/settings";
const route = useRoute();
const { sidebar } = useAppStore();
const defaultActive = computed(() => {
// .....
return route.path;
});
const settingsStore = useSettingStore();
const theme = computed(() => settingsStore.settings.theme);
const sidebarLogo = computed(() => settingsStore.settings.sidebarLogo);
</script>
<style scoped></style>完成后，npm run dev 启动，页面效果如下：
以上，就是其他全局设置项的全部内容。
