Sometimes, we want to define a JavaScript regular expression that validates a password that has special characters.
In this article, we’ll look at how to define a JavaScript regular expression that validates a password that has special characters.
How to define a JavaScript regular expression that validates a password that has special characters?
To define a JavaScript regular expression that validates a password that has special characters, we can use the (?=.*[0-9])
and (?=.*[!@#$%^&*])
patterns.
For instance, we write
const regularExpression =
/^(?=.*[0-9])(?=.*[!@#$%^&*])[a-zA-Z0-9!@#$%^&*]{6,16}$/;
to define the regularExpression
regex that has both groups.
(?=.*[0-9])
checks that the string has digits.
And (?=.*[!@#$%^&*])
checks that a string has at least 1 special character.
Conclusion
To define a JavaScript regular expression that validates a password that has special characters, we can use the (?=.*[0-9])
and (?=.*[!@#$%^&*])
patterns.
