Answer 1

you can make your own regular expression for javascript validation

    /^            : Start
    (?=.{8,})        : Length
    (?=.*[a-zA-Z])   : Letters
    (?=.*\d)         : Digits
    (?=.*[!#$%&? "]) : Special characters
    $/              : End



        (/^
        (?=.*\d)                //should contain at least one digit
        (?=.*[a-z])             //should contain at least one lower case
        (?=.*[A-Z])             //should contain at least one upper case
        [a-zA-Z0-9]{8,}         //should contain at least 8 from the mentioned characters

        $/)

Example:-   /^(?=.*\d)(?=.*[a-zA-Z])[a-zA-Z0-9]{7,}$/
