Then we use a property called validity from validation API to get the error of each input field.
The validity property gets a validity State object with the information of which validations failed and which didn’t.
Also, the ‘@’ must not be the first character of the email address, and the last dot must at least be one character after the ‘@’ sign.
Through Java Script, we can validate name, password, email, date, mobile number etc fields.
In this example, we are going to validate the name and password.
Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button.
If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information.
Now we will see how we can validate our entered form data before submitting it to the web server.
