vue 根据网站路由判断页面主题色
需求:
不同品牌对应不同版本配色
做法:
根据域名带的参数判断进入哪个品牌,对应哪个版本
在main.js中
import Vue from 'vue' import App from './App' import router from './router' import axios from 'axios' import MintUI from 'mint-ui' import { Indicator } from 'mint-ui' import { getUrls } from '@/util/utils' import 'mint-ui/lib/style.css' import './css/index.css' Vue.use(MintUI) //添加请求拦截器 loading axios.interceptors.request.use(function (config) { Indicator.open({ text: '加载中...', spinnerType: 'fading-circle' }) return config }),function (error) { Indicator.close() return Promise.reject(error) } axios.interceptors.response.use(function (config) { Indicator.close() return config }),function (error) { return Promise.reject(error) } Vue.prototype.$http = axios Vue.prototype.getUrls = getUrls router.beforeEach((to,from,next) => { if (sessionStorage.getItem('basecolor')) { document.documentElement.style.setProperty("--color", sessionStorage.getItem('basecolor')) next() } }) Vue.config.productionTip = false /* eslint-disable no-new */ new Vue({ el: '#app', router, components: { App }, template: '<App/>' })
在util.js中
export function getUrls() { let colorValue let url = window.location.href let urlArr = url.split('?') let appU = urlArr[0].split('/') let styles = getComputedStyle(document.documentElement) if (appU[appU.length-1] === 'login') { colorValue = styles.getPropertyValue('--OLAY') sessionStorage.setItem('basecolor', colorValue) this.$router.push('/login') } else if (appU[appU.length-1] === 'resetPassword') { colorValue = styles.getPropertyValue('--pampers') sessionStorage.setItem('basecolor', colorValue) this.$router.push('/login') } }
在App.vue
<template> <div id="app"> <router-view/> </div> </template> <script> export default { name: 'App', created() { this.getUrls() } } </script> <style> :root { --OLAY: rgb(237,202,138); --pampers: rgb(5,183,185); --color: #fff; } #app{ height: 100%; } </style>
