【问题描述】:
我用我自己的深色主题制作了一个深色模式按钮。主题由本地存储保存。此外,当我单击按钮时,它的图标会发生变化(月亮到太阳)。但是,如果我重新加载页面,该站点仍处于黑暗模式,但按钮图标又是月亮。所以这里有一个链接,如果你不明白我在说什么,它会告诉你问题。 (https://postimg.cc/yg6Q3vq0) 还有我的代码:
//This is the darkmode script.
function darkmode() {
const wasDarkmode = localStorage.getItem('darkmode') === 'true';
localStorage.setItem('darkmode', !wasDarkmode);
const element = document.body;
element.classList.toggle('dark-mode', !wasDarkmode);
}
function onload() {
document.body.classList.toggle('dark-mode', localStorage.getItem('darkmode') === 'true');
}
//End
//And this is the code which change the button's icon
$('button').on('click', fav);
function fav(e) {
$(this).find('.fa').toggleClass('fa-moon-o fa-sun-o');
}
//So I would like to combine the 2 codes. I mean to add the icon code to Local Storage.
.card {
color: yellow;
background-color: blue;
}
.dark-mode .car {
color: blue;
background-color: yellow;
}
