提问by TYL
I want to write a web-application on Webstorm with Angular2. I am very new on do this. I am trying the tutorial on the angular website Angular.IO.
我想用 Angular2 在 Webstorm 上编写一个 Web 应用程序。我对此很陌生。我正在尝试Angular网站Angular.IO上的教程。
When I try to make a list of Person clickable, it is not working.
当我尝试制作可点击的人员列表时，它不起作用。
export class PersonComponent {
persons = MYPERSONS;
selectedPersons = Person;
onSelect(person: Person): void {
this.selectedPerson = person; // here is the error on "this.selectedPerson"
}
}
const MYPERSONS: Person[] = [
{id:0, firstName: 'First', lastName: 'Firstly', creationData: 1},
{id:1, firstName: 'Second', lastName: 'Test', creationData:10},
{id:2, firstName: 'Third', lastName: 'Candidate', creationData:5}
];
export class Person {
id: number;
firstName: string;
lastName: string;
creationData: any;
}
I get the following error:
我收到以下错误：
Type 'Person' is not assignable to type 'typeof Person'. Property 'prototype' is missing in type 'Person'.
类型 'Person' 不能分配给类型 'typeof Person'。类型“人”中缺少属性“原型”。
What does it mean? I can't find this error on the internet. It is probably anything what I'm not seeing on the code because of my few experience
这是什么意思？我在互联网上找不到这个错误。由于我的经验很少，这可能是我在代码中没有看到的任何内容

When you write like this:
当你这样写时：
selectedPersons = Person;
you're assigning a default value of a class Person referenceto the variable selectedPersons. What you're probably intending to do is to specify that selectedPersonsclass property will hold a Personclass instance. You can do it like this:
您正在为变量分配类 Person引用的默认值selectedPersons。您可能打算做的是指定selectedPersons类属性将保存 Person类实例。你可以这样做：
selectedPersons:Person;
