Is there a way to make JSLint happy with this regex?

Question

When running my JavaScript through JSLint, I get the following two errors from the same line of code.

Problem at line 398 character 29: Insecure \'.\'.

if (pass         


        

Answer 1

That's a character class; you don't need a separator (eg: the commas). You can clean up the regex by placing the caret (^) and the dash (-) in strategic positions so they don't need to be escaped.

/[!@#$%^&*?_~()-]/

Should work. You can also use the non-word character class:

/\W/

That matches anything that's not a letter (a-zA-Z), number (0-9) or underscore (_).
