我有一个问题，当鼠标覆盖在页面上的一个元素上时，我希望切换两个div(每个div都在自己的一列中)，这时只有div(.text_2)在.item-2悬停时有反应，但我也需要text.2.2有反应并出现(这个div放在下一列)。
在这一点上，只有div(.text_2)在.item-2被悬停时有反应，但我也需要text.2.2有反应，并出现(这个div被放在下一列)。
我尝试了一些不同的方法来使之工作，例如这个
$('.item-2').hover(function() {
$('.text_2').toggleClass('hide_default');
}, function(){
$('.button-rounded').toggleClass('hide_default') {
$('.text_2.2').toggleClass('hide_default');
});
});
这是我目前的代码
$(".item-1").hover(function(){
$('#text_1').toggleClass('hide_default');
}, function(){
$('#text_1').toggleClass('hide_default');
});
$(".item-2").hover(function(){
$('.text_2').toggleClass('hide_default');
}, function(){
$('.text_2').toggleClass('hide_default');

</html>你已经从HTML中得到了结构。上一个答案 我提供的使用 data-target 来实现逻辑的通用化并保持DRY。
因此，你只需要修改选择器中的 data-target 以配合双方的 #text_2 和 #text_2.2 元素。请注意 . 中的选择符需要进行转义处理，以免被解释为类选择符。
$(".item").hover(function() {
$(this.dataset.target.replace('.', '\\.')).toggleClass('hide_default');

</div>一个更好的方法是删除 . 在 id 属性，因为它避免了与类选择器的混淆。那么JS可以变得更加简单。
