var mapData = [];

var userList =[{id:2,name:'Admin', users:[{id:2, name:'Test#1'},{id:3,name:'test#4'}]},{id:2,name:'Manager', users:[{id:2, name:'test#2'}]},{id:2,name:'Head', users:[{id:2, name:'test#3'}]}];
userList.forEach(function(element) {
  console.log(element.name)
  element.users.forEach(function (element) {
       mapData.push(element);
  })
})

mapData.forEach((element) => {
  console.log(element.name);
});

你试过使用一些if/ELSE吗?例如。

admin_users = [];
manager_users = [];

userList.forEach(function (root_element) {
  element.users.forEach(function (element) {
    switch (root_element.name) {
      case 'Admin':
        admin_users.push(element);
        break;
      // Same for other types of users.
    }
  })
})

您的管理员用户将保存在 admin_users 变量,以及 manager_users 变量

您应该考虑将其添加到数组中,而不是将用户追加到数组中。

userList.forEach(function(element) {
  console.log(element.name)
  element.users.forEach(function (element) {
       console.log(element.name);
  })
})

var userList =[{id:2,name:'Admin', users:[{id:2, name:'Test#1'},{id:3,name:'test#4'}]},{id:2,name:'Manager', users:[{id:2, name:'test#2'}]},{id:2,name:'Head', users:[{id:2, name:'test#3'}]}];

userList.forEach(function(element) {
  console.log(element.name)
  element.users.forEach(function (element) {
       console.log(element.name);
  })
})
