我有一个简单的组件,其中包括一个dreate下拉框.这个列表中填充了Web API调用的结果.出于显示目的,我只使用该项目的两个字段.但是,一旦选择了一个元素,我需要对所有其他字段进行处理.如何将整个元素传递回组件？
真的很感激任何帮助.
<h1>Get Locations</h1>
<div>
<div>
<input list="browsers" name="browser" #term (keyup)="search(term.value)">
<datalist id="browsers">
<option *ngFor="let item of items | async" >
{{item.code + " " + item.description}}
</option>
</datalist>
</div>
<input type="submit" value="Click" (click)="onSelect(item)" />
</div>
组件代码如下：
import { Component,OnInit } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { Subject } from 'rxjs/Subject';
import { LocationService } from './location.service';
import {Location} from './location.component';
import './rxjs-operators';
@Component({
selector: 'lesson-08',templateUrl: './views/lesson08.html',providers: [LocationService]
})
export class Lesson08 implements OnInit{
constructor(private locationService: LocationService) { }
aLoc: Location;
ngOnInit() {
this.aLoc = new Location();
}
errorMessage: string;
locations: Location[];
mode = 'Observable';
displayValue: string;
private searchTermStream = new Subject<string>();
search(term: string) {
this.searchTermStream.next(term);
}
onSelect(item: Location) {
// do stuff with this location
}
items: Observable<Location[]> = this.searchTermStream
.debounceTime(300)
.distinctUntilChanged()
.switchMap((term: string) => this.locationService.search(term));
}
