导出默认类路由扩展组件{

}
header=React.createRef();
setTheme=(主题)=>{
这是我的国家({
主题:主题,,
});
}
render(){
const currentLocation=this.props.location.pathname;
console.log(“位置”,currentLocation);
返回(

此.props.match.path
应该可以做到这一点您将只能访问路由
组件中的此.props.location
(当道具从组件传递到组件时)
您可以使用路由器
外部的window.location.pathname
获取当前路径,但如果您在此处访问路径,则很可能是做错了什么
对于路由器
的子级,您可以通过环绕该位置或从路由
组件向下传递道具来访问该位置
还将允许您从任何位置访问该位置 快速解决方案在函数上创建一个变量:
var currentLocation = window.location.pathname;
然后在ul>li className={(currentLocation=='/'?'active':'')中
它适用于mee,是一个快速解决方案。您可以直接从
文档
变量获取路径
例如:
const path=document.location.pathname
谢谢您的回答,我用您的建议替换了currentLocation const,并得到一个错误:无法读取undefinedSorry的属性“path”,我的命令是在路由器组件内部使用的,我相信谢谢你@riwu-这正是我所追求的。如果你想用一个引用(如密钥或名称)检索确切的路由,请检查如果你的组件在路由器之前,而不能在路由器内部,该怎么办?它不会生成
