Sir when i enter password in Password Box:- 123@Jet1
then i enter Confirm Password :- 123@Jet (showing password matched, although both password are not same) …plese fix it

It works for me when I use a test password of Pa$$w0rd

There are sites that let you test regular expressions against test inputs.

Nothing seems wrong with how the regular expression tests against your password.

Taking a closer look at the code I see the problem:

  if (password1.match(password2)) {

password2 is not a regular expression, but the above code expects it to be one.
The match method is the wrong one to use there.

You should instead just do a comparison check of both passwords strings.

Thanks for reply… if
if (password1.match(password2)) {
is a wrong method then which method i will use (i am a begineer)…Sir can you modify my code if possible

6

Do you know how to use the === comparison?

7

Do you know how to use the === comparison?
yes i know but nothing work for me…i dont know why …
i already used below code one by one but i get result Zero
“!==”
“===”
if (document.getElementById(“spanpassword”).value !==document.getElementById(“spanconfirmpassword”).value){

8

You already have both of the passwords available as the variables named password1 and password2.

You don’t need to use getElementById techniques at all to get this working.

Sir when i dont get desired output then i used different methods
problem is in Confirm Password…it giving me headache

i used
if (password1 !== password2){
document.getElementById(“spanconfirmpassword”).innerHTML=“”;
}
else{
document.getElementById(“spanconfirmpassword”).innerHTML=“Password not matched”;
}

The first body part of that if statement is clearing the message. That I expect is happening because the passwords match, but in the condition part you are checking that they don’t match.

Just use === in the condition to compare the passwords and that should start working.

Thankyou sir for give me right suggestion it is working “===”
