Promise rejection not caught: ; Zone: angular ; Task:

While using meteor and trying to set up a (click) attribute, I encountered the following error message.

https://i.sstatic.net/Qzk9T.png

This is my code:

import { Component, NgZone, AfterContentInit } from 'angular2/core';
import { NgIf, NgFor } from 'angular2/common';
import { Accounts } from 'meteor/accounts-base';
import { RouterLink, RouteConfig, Router, ROUTER_DIRECTIVES } from 'angular2/router';
import { CapitalizePipe } from '../../../../lib/pipes/capitalize.ts';
import { Groups } from '../../../../collections/groups.ts';
import { MeteorComponent } from 'angular2-meteor/meteor_component';
import { Meteor } from 'meteor/meteor';

@Component({
  selector: 'manage-players',
  templateUrl: '/client/components/loggedIn/players/manage-players.html',
  directives: [ RouterLink, NgIf, NgFor ],
  pipes: [CapitalizePipe]
})

export class ManagePlayers extends MeteorComponent {
  importPlayers: Object;
  groups: Mongo.Cursor;
  pendingImport_placementGroups: Array;
  pendingImport_players: Array;

  constructor( zone:NgZone ){
    super();
    var that = this;
    this.subscribe('groups', () => {
      this.groups = Groups.find();
    },true);
  }

  createImportGroups() {
    console.log('Do something!');
  }

This is the HTML triggering the event:

<a href="#!" class="create-import-groups btn-flat" (click)="createImportGroups()" >Create Groups</a>

Every time I click the link above, those errors show up. Apologies if there are any issues with how I presented my question or if I missed any important details – I'm still learning how to use Stack Overflow effectively.

Answer №1

After some investigation, I have come across the solution to my own inquiry, despite my limited understanding of Angular2 and javascript.

The issue at hand was caused by using an anchor tag with a click event, which clashed with Angular's handling of anchor tags and the (click) attribute.

Before:

<a href="#!" class="create-import-groups btn-flat" (click)="createImportGroups()" >Create Groups</a>

Changed to:

<button class="create-import-groups btn-flat" (click)="createImportGroups()" >Create Groups</button>

I am eager to delve deeper into this subject if more information is available.
