javascript - 单击按钮后使用 jQuery 调整 div 大小

所以我想为网页创建一个可折叠的侧边导航栏。导航栏按预期工作,但如何在单击菜单图标时让带有背景图像的 div 调整大小?折叠导航栏后,我希望背景图像占据 100% 的宽度。我添加了一些 jQuery 来在元素的类之间切换,但 div 没有变化。

The code is also here

$(document).ready(function() {
$('a').on('click', function() {
$(this).parents().siblings().children().removeClass('active');
$(this).addClass('active');
});

$('.menu-icon').on('click', function() {
$('.nav-bar').toggleClass('hide-nav');
$('main').toggleClass('expand-main');
});
});

最佳答案

1.js代码有错字,

    $('.menu-icon').on('click', function() {
$('.nav-bar').toggleClass('hide-nav');
$('.main').toggleClass('expand-main'); /*Add .main to toggleClass*/
});

2.更正后从

中删除转换属性
.expand-main {
/*transform: translateX(-25%); remove this*/
width: 100%;
}
