关于Link属性 reactjs

Question

我在Link里面添加class没反应，我看它封装的组件activeClassName是string，不知为啥就是起不到作用

<Link to={{pathname:"/printPage"}} activeClassName="dddfff" target="_blank">打印</Link>

...propTypes: {    to: oneOfType([string, object, func]),    query: object,    hash: string,    state: object,    activeStyle: object,    activeClassName: string,    onlyActiveOnIndex: bool.isRequired,    onClick: func,    target: string
  },

Answer 1

<div&nbsp;className={styles.test}> &nbsp;&nbsp;&nbsp;<Link&nbsp;to='/'>打印</Link></div>css.test&nbsp;{&nbsp;&nbsp;a&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;color:&nbsp;black; &nbsp;&nbsp;}&nbsp;&nbsp;a:active&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;color:&nbsp;red; &nbsp;&nbsp;} }
