[removed] Invalid quantifier in regex

Question

The regex is constructed on the fly, but I\'ve output it to firebug:

(.{1,38})(+|$\\n?)

the error is

invalid quantifier +|$         


        

Answer 1

The problem is the +, which is a quantifier you need to escape.

Use this instead:

/(.{1,38})(\+|$\n?)/

or inside a string:

"(.{1,38})(\\+|$\\n?)"

If you want to match the literal $ followed by a newline, you need to escape the $ with \ (or \\ inside a string - see my last comment below this for an explanation).

Here's some information on quantifiers.
