我已经接近这个汉堡包菜单了,但它仍然无法正常工作。任何帮助都会很棒。 (我敢肯定这很明显,但树木和所有这些都是森林。)对于新手来说,我的 js 似乎没有运行/触发/不管正确的词是什么。也许我链接错了?

最佳答案

更好的选择是将脚本移动到 body 标记的末尾。

如果不能,则需要包装这段代码:

$('.menu-btn').click(function(){
$('.responsive-menu').toggleClass('expand')
})

有了$(document).ready

像这样:

$(document).ready(function() {
$('.menu-btn').click(function() {
$('.responsive-menu').toggleClass('expand')
})
});
