To validate a password that contains special characters using a regular expression in JavaScript, you can use the following code:
function validatePassword(password) {
var pattern = /^(?=.*[!@#$%^&*])(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{8,}$/;
return pattern.test(password);
}
This regular expression pattern checks for the following criteria:
(?=.*[!@#$%^&*])
(?=.*[a-z])
(?=.*[A-Z])
(?=.*\d)
.{8,}
To use this function, simply pass your password string as an argument:
console.log(validatePassword("My$tr0ngP@$$w0rd")); // true
console.log(validatePassword("mypassword")); // false
