Demo

Usage

Installation

npm install angular-cc-library --save

Formating Directive

On the input fields, add the specific directive to format inputs. All fields must be type='tel' in order to support spacing and additional characters

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { CreditCardDirectivesModule } from 'angular-cc-library';

import { AppComponent } from './app.component';

@NgModule({
    imports: [BrowserModule, FormsModule, CreditCardDirectivesModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule {
}

Credit Card Formater

add ccNumber directive:

<input id="cc-number" type="tel" autocomplete="cc-number" ccNumber>

this will also apply a class name based off the card .visa, .amex, etc. See the array of card types in credit-card.ts for all available types

Expiration Date Formater Will support format of MM/YY or MM/YYYY

add ccExp directive:

<input id="cc-exp-date" type="tel" autocomplete="cc-exp" ccExp>

CVC Formater

add ccCvc directive:

<input id="cc-cvc" type="tel" autocomplete="off" ccCvc>

Validation

Current only Model Validation is supported. To implement, import the validator library and apply the specific validator on each form control

import { CreditCardValidator } from 'angular-cc-library';

@Component({
  selector: 'app',
  template: `
    <form #demoForm="ngForm" (ngSubmit)="onSubmit(demoForm)" novalidate>
        <input id="cc-number" formControlName="creditCard" type="tel" autocomplete="cc-number" ccNumber>
        <input id="cc-exp-date" formControlName="expirationDate" type="tel" autocomplete="cc-exp" ccExp>
        <input id="cc-cvc" formControlName="cvc" type="tel" autocomplete="off" ccCvc>
    </form>
  `
})
export class AppComponent implements OnInit {
  form: FormGroup;
  submitted: boolean = false;

  constructor(private _fb: FormBuilder) {}

  ngOnInit() {
    this.form = this._fb.group({
      creditCard: ['', [<any>CreditCardValidator.validateCCNumber]],
      expirationDate: ['', [<any>CreditCardValidator.validateExpDate]],
      cvc: ['', [<any>Validators.required, <any>Validators.minLength(3), <any>Validators.maxLength(4)]] 
    });
  }

  onSubmit(form) {
    this.submitted = true;
    console.log(form);
  }
}
