The language is javascript.
Strings that would pass:
JavaScript1*
Pu54 325
()9c
Strings that would not pass:
654fff
%^(dFE
I tried the following:
var matches = password.match(/\d+/g);
if(matches != null)
{
//password contains a number
//check to see if string contains a letter
if(password.match(/[a-z]/i))
{
//string contains a letter and a number
}
}

Reset to default 5You can use Regex:
I took it from here: Regex for Password
var checkPassword = function(password){
return !!password.match(/^(?=.*[A-Za-z])(?=.*\d)(?=.*[$@$!%* #+=\(\)\^?&])[A-Za-z\d$@$!%* #+=\(\)\^?&]{3,}$/);
};
I use this Regex:
Minimum 3 characters at least 1 Alphabet, 1 Number and 1 Special Character:
"^(?=.*[A-Za-z])(?=.*\d)(?=.*[$@$!%* #=+\(\)\^?&])[A-Za-z\d$@$!%* #=+\(\)\^?&]{3,}$"
This regex will enforce these rules:
At least one English letter, (?=.*?[A-Za-z])
At least one digit, (?=.*\d)
At least one special character, (?=.[$@$!% #+=()\^?&]) Add more if you like...
Minimum length of 3 characters (?=.[$@$!% #?&])[A-Za-z\d$@$!%* #+=()\^?&]{3,} include spaces
If you want to add more special characters, you can add it to the Regex like I have added '(' (you need to add it in two places).
And for those of you who ask yourself what are those two exclamation points, here is the answer: What is the !! (not not) operator in JavaScript?
