element换肤所有主题色和基础色均可自主配置
1.element-ui官方提供的动态切换主题方法换肤 但此方法只可修改$–color-primary 这一个主题色及其衍生色
2. 获取element-ui的theme-chalk/index.css文件,找到基础色所对应的颜色值,抽取颜色值进行替换,此种方法无法自动生成衍生色
{ '#67C23A': theme.color_success, '#E6A23C': theme.color_warning, '#F56C6C': theme.color_danger, '#909399': theme.color_info, }
3.自定义css变量,使用下面的方法去修改变量,此种方法仅可修改自定义的样式
document.documentElement.style.setProperty('--theme-color', value)
最终方案
以上三种相结合,实现我们的需求,各种主题色、基础色自主配置
以下是所有代码
Theme.vue
···ht-form-item
是自定义组件 和 el-form-item
差不多
