ToggleTheme.js
src/components/toolbar/js/ToggleTheme.js
import {computed, ref} from 'vue'
// ***************
// * 是否为暗色主题 *
// ***************
const isDark = ref(false)
// **********
// * 主题图标 *
// **********
const lightIcon = 'icon-sunbaitian-taiyang'
const darkIcon = 'icon-yueliangxingxing'
export const themeIcon = computed(() => isDark.value ? lightIcon : darkIcon)
// **********
// * 主题类名 *
// **********
const lightClass = 'light'
const darkClass = 'dark'
export const themeClass = computed(() => isDark.value ? darkClass : lightClass)
// **********
// * 切换主题 *
// **********
export const toggleTheme = () => {
const htmlClassList = document.documentElement.classList
if (isDark.value) {
isDark.value = !isDark.value
htmlClassList.remove(darkClass)
htmlClassList.add(lightClass)
return
}
isDark.value = !isDark.value
htmlClassList.remove(lightClass)
htmlClassList.add(darkClass)
}
Toolbar 组件

// ************
// * 工具栏状态 *
// ************
const toolbarActive = ref(false)
// *****************
// * 切换主题处理函数 *
// *****************
function toggleThemeHandler() {
toggleTheme()
toolbarActive.value = false
}
