vue项目中实现换肤（包括颜色、样式、图片）

使用vue-cli 搭建的项目，页面中很多模块都用组件实现的，当初每个组件的样式都写在了自己的style里面，本来想每个组件提取两个css文件，根据localstorage中存储的值来判断切换不同的css；

if(localStorage.getItem("colorstatus")=='neon'||localStorage.getItem("colorstatus")==null){
localStorage.setItem("colorstatus",'dark');
}else{
localStorage.setItem("colorstatus",'neon');
}

然后通过判断

colorstatus 来  require('../assets/css/neon-a.css')或 require('../assets/css/dark-a.css')

切换可以，但是第二次点击切换皮肤按钮，两个css已经都加载上了，所以必须在require加载之前将上次加载的css删除，无奈我只知道require 引入，不会删除，为了实现效果，只能把页面中所有组件的class名称写两套，一套深色皮肤，一套浅色皮肤；即nav-neon,和nav-dark 根据当前颜色来切换class，当然是比较复杂，如果有更好方法，希望推荐；

当然其中也用到了组件传值，将目前的colorstatus 传给其他组件，而且我们要有初始的皮肤，所以也要考虑页面刚加载的情况

初始化：

data () {
return {

bcolor:localStorage.getItem("colorstatus"),

}

}，

created(){
this.unloadInfo()
},

unloadInfo(){
this.$emit('load-info',this.lists[0].manager);
this.name = this.lists[0].manager;
this.$emit('color-info',localStorage.getItem("colorstatus"));
if(localStorage.getItem("colorstatus")=='neon'||localStorage.getItem("colorstatus")==null){   如果localstorage 为neon 或null(第一次使用）
this.message = require('../../assets/message.jpg');
this.config = require('../../assets/config.jpg');
this.GM = require('../../assets/images/GM.png');
this.personal = require('../../assets/images/personal-insurance.png');图片切换
this.bank = require('../../assets/images/bank-insurance.png');
this.operation = require('../../assets/images/operation.png');
}else{
this.message = require('../../assets/newimage/message2.png');
this.config = require('../../assets/newimage/config2.png');
this.GM = require('../../assets/newimage/GM2.png');
this.personal = require('../../assets/newimage/personal-insurance2.png');
this.bank = require('../../assets/newimage/bank-insurance2.png');
this.operation = require('../../assets/newimage/operation2.png');
}


},

判断皮肤变化进行切换

mounted(){
  this.$watch('bcolor', function(newVal, oldVal){
this.bcolor = newVal;
if(newVal=='neon'||newVal==null){
this.message = require('../../assets/message.jpg');
this.config = require('../../assets/config.jpg');
this.GM = require('../../assets/images/GM.png');
this.personal = require('../../assets/images/personal-insurance.png');
this.bank = require('../../assets/images/bank-insurance.png');
this.operation = require('../../assets/images/operation.png');
}else{
this.message = require('../../assets/newimage/message2.png');
this.config = require('../../assets/newimage/config2.png');
this.GM = require('../../assets/newimage/GM2.png');
this.personal = require('../../assets/newimage/personal-insurance2.png');
this.bank = require('../../assets/newimage/bank-insurance2.png');
this.operation = require('../../assets/newimage/operation2.png');
}
});
    },

样式颜色切换（更换class）

个险

当然也可以复制一份html.写两套样式，通过v-if 控制切换html，从而达到div切换，样式切换效果；

类似这个，有些笨拙和麻烦，有更好方法，还望指教；
