Angular2：如何将选定的项目从HTML datalist元素传递回组件？

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.@H_197_7@

<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：@H_197_7@

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));
    }
