在没有接口类的本地脚本Angular中绑定数据JSON,可以通过以下步骤实现:
下面是一个示例代码:
{
"users": [
{
"name": "John",
"age": 25,
"email": "john@example.com"
},
{
"name": "Jane",
"age": 30,
"email": "jane@example.com"
}
]
}
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable({
providedIn: 'root'
})
export class DataService {
private dataUrl = 'assets/data.json';
constructor(private http: HttpClient) { }
getData(): Observable<any> {
return this.http.get<any>(this.dataUrl);
}
}
import { Component, OnInit } from '@angular/core';
import { DataService } from './data.service';
@Component({
selector: 'app-root',
template: `
<h1>Users</h1>
<ul>
<li *ngFor="let user of users">{{ user.name }} ({{ user.age }})</li>
</ul>
`,
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
users: any[];
constructor(private dataService: DataService) { }
ngOnInit() {
this.dataService.getData().subscribe(data => {
this.users = data.users;
});
}
}
这样,当应用启动时,会通过服务获取JSON数据,并将其绑定到模板中的HTML元素上,实现了在没有接口类的本地脚本Angular中绑定数据JSON的功能。
