Validators

match

Installation

npm install @kovalenko/validators

Supported API

Match

Validates whether input value matches specified value

Selector: [ngcMatch]

Usage

First, import the ValidatorsModule to your module:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ValidatorsModule } from '@kovalenko/validators';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppComponent } from './app';

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

platformBrowserDynamic().bootstrapModule(AppModule);

In this example, errors will be shown when pass1 and pass2 do not match

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

@Component({
  selector: 'app',
  template: `
    <input type="password" name="pass1" [(ngModel)]="pass1">
    <input type="password" name="pass2" [(ngModel)]="pass2" [ngcMatch]="pass1" #pass2Model="ngModel">
    <div *ngIf="pass2Model.hasError('ngcMatch')">Passwords mismatch</div>
  `,
})
export class AppComponent {
  pass1: string;
  pass2: string;
}
