js替换css主题变量并切换iconfont文件

news 2025/8/7 23:28:52

iconfont不止有单色、双色的图标，还有很多【多色】的图标，于是不能【去色】，只能手动替换primary

新建一个iconfont，替换过主题色的，然后与旧的iconfont配合切换使用

主要如下：

reqiure之前必须【清除缓存】，否则无法生效，require加载机制如上图所示

const onChangeYellow = (index) => {if (appPrimary.value === "yellow") {// 重新设置主题色document.getElementsByClassName("skin-variant--semi-dark")[0].style.setProperty("--v-primary-base", "#EDE20B");document.getElementsByClassName("v-main")[0].style.setProperty("--v-primary-base", "#323232");vm.$vuetify.theme.themes.dark.primary = "#323232";// document.getElementsByTagName('html')[0].className = appPrimary.valuedocument.documentElement.className = appPrimary.value;// 清除缓存delete require.cache[require.resolve("@/assets/yellow-iconfont/iconfont")];delete require.cache[require.resolve("@/assets/yellow-iconfont/iconfont.css")];// 引入新的iconfont文件require("@/assets/yellow-iconfont/iconfont");require("@/assets/yellow-iconfont/iconfont.css");} else {document.getElementsByClassName("skin-variant--semi-dark")[0].style.removeProperty("--v-primary-base");document.getElementsByClassName("v-main")[0].style.removeProperty("--v-primary-base");// document.getElementsByTagName('html')[0].className = ''document.documentElement.className = "";// document.getElementsByClassName('yellow-iconfont')[0].remove()delete require.cache[require.resolve("@/assets/iconfont/iconfont")];delete require.cache[require.resolve("@/assets/iconfont/iconfont.css")];require("@/assets/iconfont/iconfont");require("@/assets/iconfont/iconfont.css");}
};
