How to check confirm password field in form without reloading page with JavaScript?
To check confirm password field in form without reloading page with JavaScript, we can check the input values.
For instance, we write
<label
>password :
<input name="password" id="password" type="password" />
</label>
<br />
<label
>confirm password:
<input type="password" name="confirm_password" id="confirm_password" />
<span id="message"></span>
</label>
to add the password inputs.
Then we write
const check = () => {
if (
document.getElementById("password").value ===
document.getElementById("confirm_password").value
) {
document.getElementById("message").style.color = "green";
document.getElementById("message").innerHTML = "matching";
} else {
document.getElementById("message").style.color = "red";
document.getElementById("message").innerHTML = "not matching";
}
};
const passwordInput = document.querySelector("#password");
const confirmPasswordInput = document.querySelector("#confirm_password");
passwordInput.onkeyup = check;
passwordInput.confirmPasswordInput = check;
to define the check function.
In it, we select the inputs with getElementById.
Then we get the value from each input with the value property.

Then we select the inputs and set their onkeyup property to the check function to call check as we type into the inputs.
