A password is required A password needs to have at least 4 characterss Register Section 24.3: Simple Password Change Form with Multi Control Validation The below examples use the new form API introduced in RC3. pw-change.template.html Current Password New Password New password can't be the same as current password. Confirm new password The confirmation does not match. Submit pw-change.component.ts import {Component} from '@angular/core' import {REACTIVE_FORM_DIRECTIVES, FormBuilder, AbstractControl, FormGroup, Validators} from '@angular/forms' import {PWChangeValidators} from './pw-validators' @Component({ moduleId: module.id selector: 'pw-change-form', templateUrl: `./pw-change.template.html`, directives: [REACTIVE_FORM_DIRECTIVES] }) export class PWChangeFormComponent { pwChangeForm: FormGroup; // Properties that store paths to FormControls makes our template less verbose current: AbstractControl; newPW: AbstractControl; confirm: AbstractControl; constructor(private fb: FormBuilder) { } ngOnInit() { this.pwChangeForm = this.fb.group({ GoalKicker.com – Angular 2 Notes for Professionals 105
} } current: ['', Validators.required], newPW: ['', Validators.required], confirm: ['', Validators.required] }, { // Here we create validators to be used for the group as a whole validator: Validators.compose([ PWChangeValidators.newIsNotOld, PWChangeValidators.newMatchesConfirm ]) ); this.current = this.pwChangeForm.controls['current']; this.newPW = this.pwChangeForm.controls['newPW']; this.confirm = this.pwChangeForm.controls['confirm']; pw-validators.ts import {FormControl, FormGroup} from '@angular/forms' export class PWChangeValidators { static OldPasswordMustBeCorrect(control: FormControl) { var invalid = false; if (control.value != PWChangeValidators.oldPW) return { oldPasswordMustBeCorrect: true } return null; } // Our cross control validators are below // NOTE: They take in type FormGroup rather than FormControl static newIsNotOld(group: FormGroup){ var newPW = group.controls['newPW']; if(group.controls['current'].value == newPW.value) newPW.setErrors({ newIsNotOld: true }); return null; } } static newMatchesConfirm(group: FormGroup){ var confirm = group.controls['confirm']; if(group.controls['newPW'].value !== confirm.value) confirm.setErrors({ newMatchesConfirm: true }); return null; } A gist including some bootstrap classes can be found here.
