items-text-box v1.0.2

ItemsTextBox

This is an Angular component of a textbox which allows users to input an array of text, and is compatible with Angular Reactive Forms. This component is exactly like the Chips component in Angular Material, as such this component is created for demonstration purpose only.

Usage Example

Import the ReactiveFormsModule and ItemsTextBoxModule into your app module

import {ItemTextBoxModule} from 'items-text-box';
import {ReactiveFormsModule} from '@angular/forms';

In the angular template, add the item-text-box tag wherever you need it to be. Example below shows usage with Angular ReactiveForm

<item-text-box formControlName="items" id="itemsTextBox"></item-text-box>

Sample Usage

app.component.ts

import {Component} from '@angular/core';
import {FormBuilder, FormControl, FormGroup} from '@angular/forms';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent{
  formGroup: FormGroup = this.fb.group({items: [['a','b','c']]});

  constructor(private fb: FormBuilder) {
  }

  logFormGroupValues(): void {
    console.log(this.formGroup.value);
  }

  UpdateItemsTextBox(): void {
    (this.formGroup.get('items') as FormControl).setValue(['d', 'e', 'f']);
