我想将几个接口合并为一个接口Member::
interface Person {
name?: {
firstName?: string;
lastName?: string;
};
age: number;
birthdate?: Date;
}
interface User {
username: string;
email: string;
}
interface Player {
room: number;
group?: number;
}

我的问题是:如何创建一个新接口:Member通过组合上述接口,所以我最终得到以下接口:
interface Member {
firstName: string;
lastName: string;
age: number;
birthdate?: Date;
username: string;
email: string;
room: number;
group?: number;
}

请注意,结构发生了一些变化。例如,内部字段:Person["name"]现在直接包含在新界面的根级别上。此外,这些字段现在是强制性的(以前是可选的)。
谢谢!
我在一段时间后打开一个新的标签窗口时遇到问题.我做了两个不同的实验.在第一个实验中我使用了该setTimeout(...)功能,在第二个实验中我使用了自定义sleep(...)功能.
实验1:
在这个实验中这两种浏览器:Chrome和Firefox行为以同样的方式.设置大于或等于2000毫秒的数字时,新选项卡窗口将被阻止.如果使用1000毫秒或更少,则选项卡窗口将正确打开.请假设这些数字是近似的(我的实际实验).

我有两个组件:ParentComponent和ChildComponent。
有ChildComponent一个元素,当它更改其文本时,该事件将通过事件和侦听器input[type="text"]传播到。ParentComponentchangeonChange
下面的代码是一个更大问题的简化,这就是为什么您会看到其中突出显示的一些要求。
我的问题是我需要触发change函数内的事件:handleClick。我做了一些实验,但没有运气。
