how to check confirm password field in form without reloading page

Question

I have a project in which I have to add a registration form and I want to to validate that the password and confirm fields are equal without clicking the register button.

Answer 1

You can check confirm password by only simple javascript

html

and in javascript

   function register() {

    var password= document.getElementById('password').value ;
    var confirm= document.getElementById('confirmpassword').value;

    if (confirm!=password){
      var field = document.getElementById("checkconfirm")
      field.innerHTML = "not match";
    }
  }

Also you can use onkeyup instead of onkeypress.
