导读:我正在尝试使属性fullName显示第一个和最后一个名称.如何让get属性工作? 见这Plunk. import { Component } from '@angular/core';export class Person { id: number; firstName: string; lastName: string; get fullName(): string { return this.firstName
我正在尝试使属性fullName显示第一个和最后一个名称.如何让get属性工作?
见这Plunk. import { Component } from '@angular/core'; export class Person { id: number; firstName: string; lastName: string; get fullName(): string { return this.firstName + ' ' + this.lastName; } } @Component({ selector: 'my-app',template:` <h1>{{title}}</h1> <p>My first name is {{person.firstName}}</p> <p>My last name is {{person.lastName}}</p> <h2>My full name is {{person.fullName}}!</h2>` }) export class AppComponent { title = 'Get property issue'; person: Person = { id: 1,firstName: 'This',lastName: 'That' }; } 编辑 请参阅我更新的plunk 解决方法Working PLUNKER
试试这个 import { Component } from '@angular/core'; export class Person { constructor(public id: number,public firstName: string,public lastName: string){} get fullName(): string { return this.firstName + ' ' + this.lastName; } } @Component({ selector: 'my-app',template:` <h1>{{title}}</h1> <p>My first name is {{person.firstName}}</p> <p>My last name is {{person.lastName}}</p> <h2>My full name is {{person.fullName}}!</h2> ` }) export class AppComponent { title = 'Get property issue'; person: Person = new Person( 1,'This','That'); } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
