使用Angular将对象数组从一个页面传递到另一个页面可以通过以下步骤实现:
DataSharingService
的服务。import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class DataSharingService {
private dataArray: any[] = [];
constructor() { }
setData(data: any[]) {
this.dataArray = data;
}
getData() {
return this.dataArray;
}
}
DataSharingService
,并调用setData()
方法将对象数组存储到共享服务中。import { Component } from '@angular/core';
import { DataSharingService } from '路径/DataSharingService';
@Component({
selector: 'app-sender',
template: `
<button (click)="sendData()">发送数据</button>
`
})
export class SenderComponent {
dataArray: any[] = [
{ name: '对象1', value: 1 },
{ name: '对象2', value: 2 },
{ name: '对象3', value: 3 }
];
constructor(private dataSharingService: DataSharingService) { }
sendData() {
this.dataSharingService.setData(this.dataArray);
}
}
DataSharingService
,并调用getData()
方法从共享服务中获取对象数组。import { Component } from '@angular/core';
import { DataSharingService } from '路径/DataSharingService';
@Component({
selector: 'app-receiver',
template: `
<ul>
<li *ngFor="let item of receivedData">{{ item.name }} - {{ item.value }}</li>
</ul>
`
})
export class ReceiverComponent {
receivedData: any[];
constructor(private dataSharingService: DataSharingService) { }
ngOnInit() {
this.receivedData = this.dataSharingService.getData();
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { SenderComponent } from '路径/SenderComponent';
import { ReceiverComponent } from '路径/ReceiverComponent';
@NgModule({
imports: [BrowserModule],
declarations: [SenderComponent, ReceiverComponent],
bootstrap: [SenderComponent, ReceiverComponent]
})
export class AppModule { }
通过以上步骤,你可以在Angular应用中使用共享服务来实现对象数组的传递。注意,以上示例中的路径需要根据你的项目结构进行相应的调整。
