有两个组成部分。在组件之一上是输入组。通过单击该按钮可以打开一个带有位置列表的模态窗口。
<div class="form-group form-black">
<label class="control-label">Position<label style="color:red;">*</label></label>
<div class="input-group">
<input type="text" class="form-control" id="positions_id" #positions_id='ngModel' name="positions_id" [(ngModel)]="user.positions_id" required>
<span type="submit" class="input-group-addon btn btn-info" (click)="onOpenModule();">Change position</span>
</div>
</div>
第二个组件是模态窗口本身。因此,当我打开该模式窗口并选择位置,然后单击“应用”按钮时,该帖子应输入到输入中。这是如何实现“应用”按钮的功能?
html:
<div class="col-md-12">
<table class="table table-hover">
<thead>
<tr >
<th ><b>Position</b></th>
</tr>
</thead>
<tbody>
<tr class="{{selectedPosition == position ? 'active' : ''}}" *ngFor="let position of positions" (click)="updateSelectedPosition(position?.position_id)">
<td>{{position.name}} </td>
</tr>
</tbody>
</table>
</div>
<div class="col-md-12">
<button type="submit" [disabled]="!selectedPositon?.name" class="btn btn-info pull-right">Apply</button>
</div>
ts:
import { Component, OnInit } from '@angular/core';
import { DialogRef, ModalComponent } from 'angular2-modal';
import { BSModalContext } from 'angular2-modal/plugins/bootstrap';
import { PositionService} from '../../../../services/position/position.service';
import { Position } from '../../../../models/position.model';
import { AuthService } from '../../../../services/auth/auth.service';
import { Observable } from 'rxjs/Rx';
@Component({
selector: 'app-position-modal',
templateUrl: './position-modal.component.html',
styleUrls: ['./position-modal.component.scss'],
})
export class PositionModalComponent implements ModalComponent<any> {
positions: Array<Position>;
selectedPosition = null;
constructor(
public dialog: DialogRef<any>,
public authService: AuthService,
private servPosition: PositionService
) {
this.positions = new Array<Position>();
}
ngOnInit() {
this.loadPositions();
}
private loadPositions() {
this.servPosition.getPositions().subscribe(positions => this.positions = positions);
}
updateSelectedPosition(PositionId) {
this.selectedPosition = this.positions.find(el => {
return el.position_id === PositionId
})
}
}

将这种勇气软糖用于此类物品, 您可以使用输入表单组和模式组件之间的公共服务来执行此操作,但这是一个阻力。
按照我的理解,请查看上面的链接,它将为您完成这项工作。

您可以使用Subject(来自“ rxjs”)将数据从一个组件发送到另一个。 例如。您在其中创建声明的someService-
someSubject: Subject<any> = new Subject<any>();
然后,您描述(单击)女巫中“应用”按钮的方法:
this.someService.someSubject.next("<here is the data which you want to send to another component (selectedPosition)>")
在ngOnInit()秒(不是模式组件)的最后,您订阅了此Subject并使用所需的数据进行处理:
this.someService.someSubject.subscribe(position => {
if (position) {
// here you code with sending from modal window data
}
}));
或者,如果要在Init组件上获得初始状态,则可以使用BehaviorSubject代替Subject。
