I need to validate my password such that it must contain small alphabets, capital alphabets, digits and special characters. My code looks like this:
if (password.length < 8 || !/([a-zA-Z])/.test(password) || !/([0-9])/.test(password) || !/([!,%,&,@,#,$,^,*,?,_,~])/.test(password)){
console.log('Error: password is too weak');
}
As you can see I have put up many tests in the if condition. Can I make it a single regex to achieve my purpose?
You could try this:
var regex = new RegExp("^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#\$%\^&\*])(?=.{8,})");
if (!regex.test(password)) {
console.log('Error: password is too weak');
}
(?=.*[a-z]) checks if password contains at least 1 lowercase character
(?=.*[A-Z]) checks if password contains at least 1 uppercase character
(?=.*[0-9]) checks if password contains at least 1 numeric character
(?=.*[!@#\$%\^&\*]) checks if password contains at least 1 special character.
(?=.{8,}) checks if password contains at least 8 characters or more.
