主要原理是利用webpack插件webpack-theme-color-replacer提取相关颜色css然后根据配置动态生成替换的css
具体实现步骤如下:
1.添加webpack插件,新建文件webpack/themeplugin.js
const themecolorreplacer = require('webpack-theme-color-replacer') const forelementui = require('webpack-theme-color-replacer/forelementui') const config = require('../src/config/appconfig') module.exports = new themecolorreplacer({ filename: 'css/theme-colors.[contenthash:8].css', matchcolors: [ ...forelementui.getelementuiseries(config.themecolor), //element-ui主色系列 // '#0cdd3a', //自定义颜色 ], changeselector: forelementui.changeselector, isjsugly: process.env.node_env !== 'development', // injectcss: false, // resolvecss(resultcss) { // optional. resolve result css code as you wish. // return resultcss + youcsscode // } })
matchcolors数组中可配置多个自定义要替换的主题色
2.在vue.config.js中添加这个插件
const themeplugin=require('./webpack/themeplugin'); module.exports = { configurewebpack: { plugins: [ themeplugin ] } }
3.新建文件themecolorclient.js
import client from 'webpack-theme-color-replacer/client' import forelementui from 'webpack-theme-color-replacer/forelementui' import appconfig from '@/config/appconfig' export let curcolor = appconfig.themecolor // 动态切换主题色 export function changethemecolor(newcolor) { var options = { newcolors: [...forelementui.getelementuiseries(newcolor)], } return client.changer.changecolor(options, promise) .then(() => { curcolor = newcolor localstorage.setitem('theme_color', curcolor) }); } export function initthemecolor() { const savedcolor = localstorage.getitem('theme_color') if (savedcolor) { curcolor = savedcolor changethemecolor(savedcolor) } }
4.在需要的时候调用 initthemecolor初始化颜色 changethemecolor改变主题颜色
import { initthemecolor,changethemecolor } from './utils/themecolorclient' initthemecolor() changethemecolor('#f56c6c')//传入颜色格式应该为十六进制颜色值,'red'类似颜色暂不支持
