递归遍历对象获取value值

let menu = {
        name: '一级菜单',
        data: {
            name: '二级菜单',
            data: {
                name: '三级菜单',
                data: {
                    name: '四级菜单'
                }
            }
        }
};
function f(s){
  for(var i in s){
   if(typeof s[i]=="object"){
      f(s[i])
   }else{
　　　console.log(s[i]);
　　}
  }
}
f(menu);
