'button-fill' 我没有找到个class标签在哪 请求助 搞不懂
// 若之前已选定了别的category,则移除其选定效果，改成选定新的
if ($(e.target).hasClass('button-fill')) {
$(e.target).removeClass('button-fill');
shopCategoryId = '';
} else {
$(e.target).addClass('button-fill').siblings()
.removeClass('button-fill');
}
尤其这两段是什么妖魔鬼怪啊

同学你好！
老师在这段代码上添加了详细的注释，同学可以看一下（这里其实就是在实现选中类别时样式的变化）
为什么一直都是添加移除button-fill类呢，原因是因为这是我们所引入的前端框架中的，在框架中给button-fill设置了css，这样我们就可以直接引用框架中的样式，不需要自定义了
如果我的回答解决了你的疑惑，请采纳，祝学习愉快~
