write custom validation

import {abstractcontrol} '@angular/forms'; export class passwordvalidation {  static matchpassword(ac: abstractcontrol) {    let password = ac.get('password').value; // value in input tag    let confirmpassword = ac.get('confirmpassword').value; // value in input tag     if(password != confirmpassword) {         console.log('false');         ac.get('confirmpassword').seterrors( {matchpassword: true} )     } else {         console.log('true');         return null     } }  } 

in componet add custom validator this

import { passwordvalidation } './password-validation'; this.form = fb.group({   password: ['', validators.required],   confirmpassword: ['', validators.required] }, {   validator: passwordvalidation.matchpassword // validation method })
