You can prefer this way. works most time:
<user-input #input type="password" ></user-input>
<button (click)="changeInput(input)">Change input</button>
ts file
changeInput(input: any): any {
input.type = input.type === 'password' ? 'text' : 'password';
}

I was wondering if anyone can help explain why i am unable to change form input type dynamically?
For e.g.
<user-input type="{{ isActive ? 'password' : 'text' }}"></user-input>
doesn't work.
But this works,
<user-input type="password" *ngIf="isActive"></user-input> <user-input type="text" *ngIf="!isActive"></user-input>
user-input.ts
import { Component, Input } from '@angular/core'; @Component({ selector: 'user-input', templateUrl: './user-input.html' }) export class UserInput { @Input() public isActive: boolean; constructor() { } }
user-input.html
<input type="{{ isActive ? 'password' : 'text' }}" class="form-control" [(ngModel)]="value" />
user-input-password.ts import { Directive, HostListener } from '@angular/core'; @Directive({ selector: 'input[type=password][formControlName],input[type=password][formControl],input[type=password][ngModel]' }) export class PasswordValueAccessor { public pattern: RegExp; private regexMap = /^(?=.*[0-9])(?=.*[!@#$%^&*])[a-zA-Z0-9!@#$%^&*]{6,16}$/; @HostListener('keypress', ['$event']) public onKeyPress (e: any) { this.pattern = this.regexMap; const inputChar = e.key; if (this.pattern.test(inputChar)) { // success } else { e.preventDefault(); } } }
The issue i have is that when i set the type dynamically, the user-input-password directive doesn't get triggered. If i set the type to password directly then it does get trigged.
Is there another way to dynamically change input type?

Ramesh Rajendran about 6 yearsI hope he want to change the type at default load.

ymrs about 6 years@Anas Bin Nazeer, unfortunately i don't have a button on the page to do this. I want to be able to change the type on load.
