使用子组件按钮单击关闭 Kendo Angular 对话框

Question

我有一个表单组件，使用 kendo 对话框服务将其嵌入到对话框中。我可以调用我的服务并在保存单击时保存表单数据。我试图弄清楚如何在单击保存后关闭对话框。我想将所有逻辑保留在对话框组件中，只从父组件中打开对话框。验证和保存调用将在对话框组件中进行。我可以只使用模板并将保存/关闭函数放置在父组件中，但我想将其隔离到对话框服务使用的子组件。

客户端组件.ts

    import { AddClientComponent } from './add-client.component';
import { Component, OnInit } from '@angular/core';
import { ClientService } from '../services/client.service';
import { DialogService, DialogCloseResult, DialogRef } from '@progress/kendo-angular-dialog';

@Component({
    selector: 'clients',
    templateUrl: 'ClientComponent.html',
    styleUrls: ['../app.component.css'],
    moduleId: module.id
})
export class ClientsComponent implements OnInit {
    public clients: any[];
    private title = 'Clients';

    constructor(private clientService: ClientService, private dialogService: DialogService) {

    }

    ngOnInit() {
        this.clients = this.clientService.getClients();
    }

    public showAddClient() {
        const dialog: DialogRef  = this.dialogService.open({
            title: "Add User",

            // show component
            content: AddClientComponent
        });

        dialog.result.subscribe((result) => {
            if (result instanceof DialogCloseResult) {
                console.log("close");
            } else {
                console.log("action", result);
                this.clients = this.clientService.getClients();
            }
        });
    }
}

clientComponent.html

<h1>{{title}}</h1>

<br/>

<button (click)="showAddClient(dialogActions)" class="k-button">Add Client</button>

<kendo-grid [data]="clients">
    <kendo-grid-column field="Id" title="Id">
    </kendo-grid-column>
    <kendo-grid-column field="FirstName" title="FirstName">
    </kendo-grid-column>
    <kendo-grid-column field="LastName" title="LastName">
    </kendo-grid-column>
    <kendo-grid-column field="DateOfBirth" title="DateOfBirth">
    </kendo-grid-column>
    <kendo-grid-column field="Location" title="Location">
    </kendo-grid-column>
</kendo-grid>

<div kendoDialogContainer></div>

添加-client.component.ts

import { Component, Input } from '@angular/core';
import { ClientService } from '../services/client.service';
import { Client } from '../entities/Client';

@Component({
  selector: 'add-client',
  templateUrl: 'AddClient.html',
  moduleId: module.id
})
export class AddClientComponent {

    constructor(private clientService: ClientService) {

    }

    public firstName: string;
    public lastName: string;
    public dateOfBirth: Date;
    public address: string;

    public Save() {

        var client = new Client(0, this.firstName, this.lastName, this.dateOfBirth, this.address)
        this.clientService.addClient(client);
    }
}

添加客户端.html

<form class="k-form">
    <label class="k-form-field">
        <span>First Name</span>
        <input class="k-textbox" placeholder="Your Name" [(ngModel)]="firstName" name="firstName" />
    </label>
    <label class="k-form-field">
        <span>Last Name</span>
        <input class="k-textbox" placeholder="Your Last Name" [(ngModel)]="lastName" name="lastName" />
    </label>
    <label class="k-form-field">
        <span>Date of Birth</span>
        <kendo-datepicker name="birthDate"
                          [(ngModel)]="birthDate"></kendo-datepicker>
    </label>
    <label class="k-form-field">
        <span>Location</span>
        <input class="k-textbox" placeholder="Perrysburg" [(ngModel)]="location" name="location" />
    </label>

    <button class="k-button pull-right" (click)="Save()" primary="true" style="background-color:deepskyblue">Save</button>
</form>

现在有一种更好、更简单的方法可以做到这一点。你可以查看文档

https://www.telerik.com/kendo-angular-ui/components/dialogs/dialog/service/

基本上，您所要做的就是在子组件中提供 DialogRef 类型的构造函数参数。

add-client.component.ts 看起来像这样：

import { Component, Input } from '@angular/core';
import { ClientService } from '../services/client.service';
import { Client } from '../entities/Client';
import { DialogRef } from '@progress/kendo-angular-dialog';

@Component({
    selector: 'add-client',
    templateUrl: 'AddClient.html',
    moduleId: module.id
}) 

export class AddClientComponent {

    constructor(private clientService: ClientService,
    public dialog : DialogRef) {

    }

    public firstName: string;
    public lastName: string;
    public dateOfBirth: Date;
    public address: string;

    public Save() {

        var client = new Client(0, this.firstName, this.lastName, this.dateOfBirth, this.address)
        this.clientService.addClient(client);
        this.dialog.close();
    }
}
