Question

我是PrimeNG的新手，但我发现你可以用它创造美好的东西。我试图从PrimeNg建立一个咆哮但我不断收到这个错误“无法绑定到'值'，因为它不是'p-growl'的已知属性”。我使用了PrimeNG的“消息”，这个工作正常，所以我不知道我做错了什么，因为另一个确实有效。

我的组件ts

import {Component, OnInit} from '@angular/core';
import {IMailModel} from '../models/mail.model';
import {MailService} from '../Services/mail.service';
import {Message} from 'primeng/primeng';


@Component({
    selector: 'coordinator-invitations',
    moduleId: module.id,
    templateUrl: 'coordinatorInvitations.component.html',
    styleUrls: ['../../assets/css/in/content.css'],
})

export class CoordinatorInvitationsComponent implements OnInit {
    listReceivers: IMailModel[];
    listSenders: IMailModel[];
    pageTitle: string = 'Uitnodigingen versturen';
    errorMessage: string;
    msgs: Message[] = [];
    msgsGrowl: Message[] = [];
    subject: string = "";
    text: string="";
    success: boolean;


    constructor(private _mailService: MailService) {

    }

    ngOnInit(): void {
        this._mailService.getMailAddresses()
            .subscribe(listSenders => this.listSenders = listSenders,
                error => this.errorMessage = <any>error);
        this.listReceivers = [];
    }

    onclick(): void {
      this.msgs=[];
      this.success=true;
      if(this.listReceivers.length===0) {
        this.msgs.push({severity:'error', summary:'Error', detail:'Er zijn geen ontvangers geselecteerd.'});
        this.success=false;
      }
      if(this.subject.length===0)
      {
        this.msgs.push({severity:'error', summary:'Error', detail:'Er is geen onderwerp opgegeven.'});
        this.success=false;
      }
      if(this.text.length===0)
      {
        this.msgs.push({severity:'error', summary:'Error', detail:'Er is geen inhoud ingegeven.'});
        this.success=false;
      }

      if(this.success===true)
      {
        this.msgsGrowl.push({severity:'success', summary:'Succes', detail:'De uitnodigingen zijn succesvol verstuurd.'});
      }
    }
}

我的组件HTML

    <span>{{pageTitle}}</span>

TL; DR：我的PrimeNG消息模块有效，但我的PrimeNG Growl模块不起作用

Answer 1

从app.module.ts中的primeng导入GrowlModule。

my_loss = tf.losses.log_loss(labels, predictions)
my_running_loss, update_op = tf.metrics.mean(my_loss)

然后将GrowlModule添加到app.module.ts的导入部分。

import { GrowlModule } from 'primeng/primeng';

注意： - 当您导入primeng / primeng时，它会在项目中带来primeng的所有api，这可能会增加您的项目的大小。

Answer 2

您需要在组件中导入GrowlModule

import {GrowlModule,Message} from 'primeng/primeng';

Answer 3

服务器重启修复了这个问题，但重启后我发现当你在同一页面上使用Message and Growl组件时它会开始窃听。

PrimeNG Growl无法绑定到'value'，因为它不是'p-growl'的已知属性
