DaisyUI指南

主题切换

参考主题控制器。以下甄选了几个好看的主题。

/** @type {import('tailwindcss').Config} */
export default {
  content: ["./src/**/*.{html,js,vue}"],
  theme: {
    extend: {},
  },
  plugins: [require("daisyui")],
  daisyui: {
    themes: [
      "light",
      "dark",
      "halloween",
      "garden",
      "forest",
      "lofi",
      "pastel",
      "fantasy",
      "wireframe",
      "dracula",
      "cmyk",
      "autumn",
    ], // false: only light + dark | true: all themes | array: specific themes like this ["light", "dark", "cupcake"]
    darkTheme: "dark", // name of one of the included themes for dark mode
    base: true, // applies background color and foreground color for root element by default
    styled: true, // include daisyUI colors and design decisions for all components
    utils: true, // adds responsive and modifier utility classes
    prefix: "", // prefix for daisyUI classnames (components, modifiers and responsive class names. Not colors)
    logs: true, // Shows info about daisyUI version and used config in the console when building your CSS
    themeRoot: ":root", // The element that receives theme color CSS variables
  },
}

我的主题切换器

其中 tabindex=“0” 代表元素能否通过进行聚焦（用点的或者Tab键），此处第一个tabindex="0"不能省略，因为下面的ul的dropdown-content的底层css样式写的就是：上面那个Theme div聚焦了，下面这个列表才显示。至于第二个ul的聚焦，没啥用，可以删掉，因为input能直接聚焦。

通过 :checked=“index == themeIndex”来初始化主题选择器的radio的选项默认选中。

<template>
    <div class="dropdown">
        <div tabindex="0" role="button" class="btn m-1">
            Theme
            <svg width="12px" height="12px" class="h-2 w-2 fill-current opacity-60 inline-block"
                xmlns="http://www.w3.org/2000/svg" viewBox="0 0 2048 2048">
                <path d="M1799 349l242 241-1017 1017L7 590l242-241 775 775 775-775z"></path>
            </svg>
        </div>
        <ul tabindex="0" class="dropdown-content z-[1] p-2 shadow-2xl bg-base-300 rounded-box w-52">
            <li v-for="(theme, index) in themeList" @click="changeTheme(index, theme)">
                <input type="radio" name="theme-dropdown"
                    class="theme-controller btn btn-sm btn-block btn-ghost justify-start" :aria-label="theme"
                    :value="theme" :checked="index == themeIndex" />
            </li>
        </ul>
    </div>
</template>

<script setup>
import { ref, onMounted } from 'vue';
import { useThemeStore } from '@/stores/themeStore';

const { changeThemeTo, getCurrentThemeIndex } = useThemeStore();

const themeIndex = ref(0);
const themeList = ref([
    "light",
    "dark",
    "halloween",
    "garden",
    "forest",
    "lofi",
    "pastel",
    "fantasy",
    "wireframe",
    "black",
    "luxury",
    "dracula",
    "cmyk",
    "autumn",
])

function changeTheme(index, themeName) {
    themeIndex.value = index;
    changeThemeTo(index, themeName);
}

onMounted(() => {
    themeIndex.value = getCurrentThemeIndex();
})

</script>

<style scoped></style>

以下是pinia持久化的内容。

//themeStore.js
import { ref } from 'vue'
import { defineStore } from 'pinia'

export const useThemeStore = defineStore('theme', () => {
    const theme = ref('light');
    const themeIndex = ref(0);

    function initialTheme() {
        let html = document.getElementsByTagName('html')[0];
        html.setAttribute('data-theme', theme.value);
    }

    function changeThemeTo(index, themeName) {
        themeIndex.value = index;
        theme.value = themeName;
    }

    function getCurrentThemeIndex() {
        return themeIndex.value;
    }

    return { theme, themeIndex, initialTheme, changeThemeTo, getCurrentThemeIndex }
}, {
    persist: true
})

即便在控制器中初始化了默认radio的默认选中，但是在App.vue的onMounted函数中调用初始化主题仍然是必要的。因为主题控制器大多在导航栏中，而有的登陆界面中没有导航栏，意味着主题控制器未生效，此时需要根据本地数据主动初始化主题。

封装好的PopingAlert
