[英]Light/Dark Theme Toggle
我正在尝试创建一个 HTML 页面，在单击按钮时，主题从深色变为浅色。
我的问题是菜单图标。 如果更改为深色主题，然后打开和关闭菜单，则显示的浅色和深色主题菜单图标或弹出菜单内部不会显示任何内容，甚至是关闭菜单的菜单图标。
我在这里做错了吗？

从一个主题切换到另一个使用不同的样式标签
示例代码：
(function( ColorThem ) { let themes = document.querySelectorAll('style.theme') , current = 0 ; themes.forEach((st, i)=>st.disabled=(i!==current)) ; ColorThem.switch = function( ) { current = ++current % themes.length themes.forEach((st, i)=>st.disabled=(i!==current)) } }(window.ColorThem=window.ColorThem || {})); document.querySelector('#bt-theme-switch').onclick = ColorThem.switch; /* document.querySelector('#theme-Light').disabled = true; document.querySelector('#theme-Dark').disabled = false; */
<style class='theme' id='theme-Dark' > body { background-color: darkslategrey;} p { color: yellow;} </style> <style class='theme' id='theme-Light' > body { background-color:floralwhite;} p { color: black;} </style> <p> some things </p> <button id="bt-theme-switch"> switch theme </button>
对于图标，您可以使用空的 div 并使用具有宽度、高度和背景（图像和位置）属性的 css 来设置它们的样式（这样做而不是通过 html 放置图像）。 然后在 jquery 中，正如您在其余部分所做的那样，使用单击功能添加/删除具有其他背景样式的类。
我不知道，但这段代码是从@Mister Jojo 重构的，区别不大，我碰巧发现很难理解他的。
const switchButton = document.getElementById('button-switch') const themeStyles = document.querySelectorAll('style.theme') switchButton.addEventListener('click', toggleTheme) themeStyles[0].disabled = true function toggleTheme() { themeStyles.forEach(x => { x.disabled = !x.disabled }) }
<style class='theme --dark'> body { background: black; color: white; } </style> <style class='theme --light'> body { background: white; color: black; } </style> <p> paragraph </p> <button id="button-switch"> switch theme </button>
