worked good but changed it to {9,} because a password greater than 8 characters means at least 9 – bestbballplayer Dec 04 '16 at 06:19

You can try this one.

/(.{7,}(?=[#?!@$%^&*-])|(?=[#?!@$%^&*-]).{7,})/

This function can be used. Pass in a the password string to test it. If it is longer than 8 characters i will get tested by the RegEx test to see if there is a special character. If there is a special character it returns true if there is none them the "Password is either....." text is returned.

function passWrdTest(str){
    var myReg = /\[|\#|\?|\!|\@|\$|\%|\^|\&|\*|\-|\]/g;
    return str.length > 8 ? myReg.test(str) : 'Password is either not long enough or does not have a special character...';
}
