我正在开发一个reactjs应用程序 - 标题菜单是一个antd菜单，页脚链接是NavLinks ..我的问题源于正确设置菜单 - 我试图提供路由级别的CURRENT页面 - 并将其提供给页眉/页脚组件。
应用程序不稳定 - 我刷新主页上的页面是活动的 - 如果我刷新页面上的条款它不选择主页链接 - 但页脚中的链接未设置为选择 - - 并且组件之间的通信不存在 - 如果我点击它就选择帐户 - 然后转到页脚链接等。
这是应该或可以由redux商店处理的东西 - 如果是这样，如何实现这个？正常？
对此有何建议？
const mapStateToProps = (state) => {
return {
current_page: state.current
}
}
const { bool, string, func } = React.PropTypes
Header.propTypes = {
current_page: string
}
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Header))
代码目前看起来像这样。 http://jsfiddle.net/0ht35rpb/105/
