Question

looking to validate a password, currently i have

var myRegularExpression = /(?=.*?[#?!@$%^&*-]).{8,}/ ;

am i missing something? it can contain anything but the only requirements it must have are at least 1 special character and be greater than 8 characters

Answer 1

use this ^(?=. ?[#?!@$%^& -]).{8,}$

you can see the details here

Answer 2

你可以试试这个。

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

Answer 3

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...';
}
