在javascript onclick中添加样式到标记

Question

我有这个工作的JavaScript，我想再一个功能。我想这样，如果我点击例如“公平交易”，文字颜色应该改变，如果我现在按下例如“Toxicfree”它应该淡化那种风格并淡入新风格。

这是为了确保用户知道他们选择了什么标题并正在阅读。

感谢所有帮助！

var $imgs = $(".section-link");

向选定的div添加一个类，然后为该类赋予特殊颜色。

在css中使用Base = declarative_base() class Lablable(Base): __tablename__ = 'lablables' label_id = db.Column(db.Integer, db.ForeignKey('labels.id'), primary_key=True) lablable_id = db.Column(db.Integer) lablable_type = db.Column(db.String(100)) labels = db.relationship("Label") class Label(db.Model): __tablename__ = "labels" id = db.Column(db.Integer, primary_key=True, autoincrement=True, nullable=False) caption = db.Column(db.String(200)) class Country(db.Model): __tablename__ = "countries" lablable_id = db.Column(db.Integer(), db.ForeignKey('lablables.id')) lables = association_proxy('lablables', 'label', creator=lambda x: Lablable(x=label)) 为淡入式淡出样式设置动画：

transition

-webkit-transition: all .5s ease-in-out; -moz-transition: all .5s ease-in-out; -ms-transition: all .5s ease-in-out; -o-transition: all .5s ease-in-out; transition: all .5s ease-in-out; 意味着半秒钟。您可以根据需要增加或减少数量

.5s

var $imgs = $(".section-link");


var data = [{
    title: "Fair Trade",
    text: "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
