Need a fresh set of eyes on a Javasript edit

[JCCDEVEL]

Hello All, I'm getting frustrated with the syntax of a jscript edit I'm using on a VBScript page. Here is what I have:

var re = /[$\\@\\\#%\^\&\*\(\)\[\]\+\_\{\}\`\~\=\|]/;
if (!re.test(document.login.NewUserPassword.value))
{
AlertMessage += "Invalid entry! You must also use nonalphanumeric characters!";
focusfield =document.login.NewUserPassword;
}

and when I run it I get "error: undefined is "null" or not an object"

Basically, it is a password reset page and one of the rules is that the new p-word has to have non-alphanumerics in it. I know it is something minor, but I have stared at it so long

Thanks in advance for your ideas!

this is just a shot in the dark but maybe add quotes:

var re = "/[$\\@\\\#%\^\&\*\(\)\[\]\+\_\{\}\`\~\=\|]/";
 

and what is test? can u post its source?

good luck

Thanks for your speedy reply! It is syntax I borrowed from a site that has lots of javascript examples. The specific one I borrowed from looked like this:

var re = /[$\\@\\\#%\^\&\*\(\)\[\]\+\_\{\}\`\~\=\|]/
if (!re.test(str)) return false;

I thought that "test" was a function. I'm open to doing it another way, just thought that this looked pretty straightforward!

The funny things is I had this thing somewhat working on Friday, and now it doesn't work!

hi ...

yes ... test() is a build in js-method that may be used the following way:

// regEx that requires all chars as numeric
var re = /^\d+$/; 
 
// this returns true
re.test('111');
 
// this returns false
re.test('111a');
 

kind regards ...

... i tested your regEx ... it seems to be ok ... may be your value is not referenced correctly? is document.login.NewUserPassword defined in your page?

kind regards ...

Thank you so much for your help. This what I ended up using:

if (!((document.login.NewUserPassword.value.search(/[a-z]+/) > -1) && (document.login.NewUserPassword.value.search(/[A-Z]+/) > -1) && (document.login.NewUserPassword.value.search(/[0-9]+/) > -1) && (document.login.NewUserPassword.value.search(/[^a-zA-Z0-9_]+/) > -1)))


and it is working well

Thanks for sharing your knowledge!
