本篇文章是【Vue+Koa2+Mysql全栈撸win10格调管理系统】交个敌人系列之主题切换计划
先来一个主题切换效果图,次要实现背景图片的切换和主题色的切换,而且刷新浏览器还是能放弃
一、实现性能次要技术点
1、利用localStorage浏览器本地存储主题设置信息(当然也能够存储在数据库里)
2、scss抽离主题文件中波及到色彩的 CSS 值替换成关键词
3、实时监听localStorage的变动,关键词再换回生成的相应的色彩值或者背景图片
二、抽取主题变量,封装mixin
在目录 styles/theme-variable.scss
先把主题文件中波及到色彩的 CSS 值替换成关键词,做了个别中央进行皮肤切换
$background-color-theme1: #409EFF;
$background-color-theme2: #0078D7;
$background-color-theme3: #C30052;
$background-color-theme4: #9A0089;
$background-color-theme5: #67C23A;
$background-color-theme6: #CA5010;
$background-color-theme7: #CA5010;
$background-color-theme8: red;
$background-color-theme9: #303133;
$background-color-theme10: #606266;
$background-color-theme11: #909399;
$background-color-theme12: #C0C4CC;
$background-color-theme13: #DCDFE6;
$background-color-theme14: #E4E7ED;
$background-color-theme15: #EBEEF5;
$background-color-theme16: #FFFFFF;
$font-color-black: #303133;
$font-color-white: #FFFFFF;
$startMenu-background-color-black: rgba(19, 23, 28, 0.9);
$startMenu-background-color-white: #F2F6FC;
在目录 styles/theme-mixin.scss
设置背景色彩封装成一个mixin办法(包含字体大小,字体色彩,进行封装),@mixin通过自定义属性[data-theme=””]去辨认对应的色彩变量
@mixin background-color($color) {
background-color: $color;
[data-theme="theme1"] & {
background-color:$background-color-theme1;
}
[data-theme="theme2"] & {
background-color:$background-color-theme2;
}
[data-theme="theme3"] & {
background-color:$background-color-theme3;
}
[data-theme="theme4"] & {
background-color:$background-color-theme4;
}
[data-theme="theme5"] & {
background-color:$background-color-theme5;
}
[data-theme="theme6"] & {
background-color:$background-color-theme6;
}
[data-theme="theme7"] & {
background-color:$background-color-theme7;
}
[data-theme="theme8"] & {
background-color:$background-color-theme8;
}
[data-theme="theme9"] & {
background-color:$background-color-theme9;
}
[data-theme="theme10"] & {
background-color:$background-color-theme10;
}
[data-theme="theme11"] & {
background-color:$background-color-theme11;
}
[data-theme="theme12"] & {
background-color:$background-color-theme12;
}
[data-theme="theme13"] & {
background-color:$background-color-theme13;
}
[data-theme="theme14"] & {
background-color:$background-color-theme14;
}
[data-theme="theme15"] & {
background-color:$background-color-theme15;
}
[data-theme="theme16"] & {
background-color:$background-color-theme16;
}
}
在页面上须要用到切换肤色的中央援用样
@import "~@/styles/theme-mixin.scss";
@import "@/styles/theme-variable.scss";
@include background-color($background-color-theme1); //援用背景色彩设置
@include font-color($font-color-white); //援用字体设置
例如在layout页面布局里相干文件里(局部展现),这里是根底scss技能不再做过多的解说
<style lang="scss" scoped>
@import "~@/styles/theme-mixin.scss";
@import "@/styles/theme-variable.scss";
.window-wrapper {
position: absolute;
min-width: 1280px;
min-height: 80%;
z-index: 9;
.window-header {
height: 40px;
line-height: 40px;
@include background-color($background-color-theme1);
transition: all .5s;
display: flex;
.window-title {
flex: 1;
padding-left: 10px;
user-select: none;
color: #fff;
@include font-color($font-color-white);
transition: all .5s;
三、主题色彩设置
在目录 src/views/config/coloer/index.vue
中更换主题时的操作代码
<template>
<div class="colour-wrapper">
<preview></preview>
<div class="set-wrapper">
<div class="title">主题色</div>
<div class="colour-list">
<div v-for="index of 16" :key="index" :class="'theme-color-'+index" @click="changeTheme(index)"></div>
</div>
</div>
</div>
</template>
<script>
import preview from '@/components/preview.vue'
import { localKey } from '@/settings'
export default {
components: {
preview
},
data() {
return {
}
},
methods:{
changeTheme(index) {
let theme = "theme" + index
window.document.documentElement.setAttribute('data-theme', theme)
}
}
}
</script>
通过再抉择主题的时候,我在这里主题色16个能够抉择,列表是用v-for
列表渲染进去的,每个色彩绑定一个一个点击事件,通过DOM操作在设置自定义属性[data-theme],会在html里增加自定义属性data-theme,这样就是实现了皮肤切换
然而这样有什么毛病呢?
当你刷新浏览器的时候,你会发现这个设置就不失效了,
所以接下来思考存储到浏览器缓存里去
四、localStorage本地存储主题设置
总所周知,vue无奈监听localstorage的变动的,这里通过注册全局办法,而后通过事件派发的形式实现localstorage的响应式
依据咱们我的项目中的主题相干的属性,目前有主题和背景图相干的设置存储在一个对象里
咱们在 src/utils/storage.js
里针对原生localStorage 的api都封装一层,生成本人的专用主题设置模块存储派发模块
export const dispatchSetLocalStore = (key, type, value) => {
let settings = _getLocalStore(key,'JSONStr') || {
theme: 11,
taskbarMode: 'bottom',
bgSrc: ''
}
switch(type) {
case 'bgSrc':
settings.bgSrc = value
break
case 'theme':
settings.theme = value
break
case 'taskbarMode':
settings.taskbarMode = value
break
}
settings = JSON.stringify(settings)
// 创立一个StorageEvent事件
let newStorageEvent = document.createEvent('StorageEvent');
const storage = {
setItem: function (k, val) {
localStorage.setItem(k, val)
// 初始化创立的事件
newStorageEvent.initStorageEvent('setItem', false, false, k, null, val, null, null)
// 派发对象
window.dispatchEvent(newStorageEvent)
}
}
return storage.setItem(key, settings)
}
而后在src/main.js
对vue增加一个原型属性
import { dispatchSetLocalStore } from './utils/storage'
Vue.prototype.setLocalStore = dispatchSetLocalStore
此时此刻咱们就能够在vue文件里监听到变动了
<template>
<div id="app" :style="{ background: 'url('+bgSrc+')'}" :data-theme="theme">
<router-view />
</div>
</template>
<script>
import { _getLocalStore } from '@/utils/storage'
import { localKey } from '@/settings'
export default {
name: 'App',
data() {
return {
bgSrc: _getLocalStore(localKey, 'JSONStr') && _getLocalStore(localKey, 'JSONStr').bgSrc ? _getLocalStore(localKey, 'JSONStr').bgSrc : require('@/assets/bg_01.jpg'),
theme: _getLocalStore(localKey, 'JSONStr') && _getLocalStore(localKey, 'JSONStr').theme ? _getLocalStore(localKey, 'JSONStr').theme : 'theme1'
}
},
created(){
window.addEventListener('setItem', () => {
let local = _getLocalStore(localKey, 'JSONStr')
this.bgSrc = local && local.bgSrc ? local.bgSrc : this.bgSrc
this.theme = local && local.theme ? local.theme : this.theme
})
},
}
</script>
在目录 src/views/config/coloer/index.vue
中更换主题时的操作代码
此时就不是 window.document.documentElement.setAttribute('data-theme', theme)
而是this.setLocalStore(localKey, 'theme', theme)
五、总结
换肤的形式次要是对波及到色彩的 CSS 值替换成关键词,依据用户抉择的主题色生成一系列对应的色彩值,用户选的主题设和背景图片通通通过键值对存储在localstorage,而后通过全局事件派发,响应式获取localstorage,通过自定义属性的属性值,对应把关键词再换回刚刚生成的相应的色彩值,切换背景图片,而后别离对其加一些切换动画,显得换肤和切换背景图片天然~
