Angular 2数据问题 [英] Angular 2 data issue

问题描述

I have a component which is properly being called from the .ts file but it's still not returning the data.

And have a service

        import {Component} from 'angular2/core'
        import {AuthorServices} from './author.service'
       @Component 
       ({
    selector: 'author',
    template: `
                <h1>Authors</h1>
                    {{title}}
                    <ul>
                        <li ngFor ="#auth of author">
                            {{auth}}
                        </li>
                    </ul>
    `,
    providers: [AuthorServices]})

    export class AuthorComponent{
             title ="Name of Author";
             authors;
             constructor(authorServices : AuthorServices){
             this.authors = authorServices.getAuthor();
            } }

    export class AuthorServices{
    
    getAuthor(): string[]{
        
        return ['Paul','Eva','Nicholas'];
        }}

It should return array along with its title. But I am not sure where it's getting stuck. Please Help!

I tried changing the tags, checked the directives and also the calls made accross

推荐答案

进行的调用请尝试关注并告诉我如果这不起作用你 -

Please try following and let me know if that doesn't work for you-

<ul>
   <li *ngFor="let auth of authors">
    {{auth}}
   </li>
</ul>

为什么？因为您的数组名称是 authors 而不是 author 。



希望，它有助于：）

Why? Because your array name is authors and not author.

Hope, it helps :)
