使用子组件按钮单击关闭 Kendo Angular Dialog

Question

我有一个表单组件，我使用 kendo 对话服务将其嵌入到对话中。我可以调用我的服务并在保存点击时保存我的表单数据。我试图弄清楚如何在点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，然后从父组件打开对话框。验证和保存调用将发生在对话框组件中。我可以只使用模板并将保存/关闭功能放在父组件中，但我想将其隔离到对话服务使用的子组件中。

ClientComponent.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

import { Component, Input } from '@angular/core';

    }

    public firstName: string;

    public Save() {

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

        <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。您可以查看文档

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

基本上你要做的就是在子组件中提供一个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();
    }
}

您可以在此处查看我对关于防止对话框在按下操作按钮后关闭的类似问题的回答

how to add callbacks to kendo dialog actions

然后您可以在关闭对话框之前直接调用对话框实例上的函数，这样您就可以将所有逻辑保留在对话框组件中。
