Javascript Regular expression error in get string between two strings

Question

I have string look like this :

"fdsgsgf.signature=xxxxx(bv)"

And i want to get xxxxx

With : var testRE = html.match(".signature=(.*)/\(");

And when i run it i get exception that it's not valid regex.

Any idea why?

non regex solution.. html.split("=")[1].split("(")[0].. can make better though. — Mr_Green

Use a regular expression literal instead of a string literal. — Bergi

Some issues with your code:

You're missing starting slash / of your regex
Instead of .* you should better use [^(]+
dot needs to be escaped

Modified code:

html.match(/\.signature=([^(]+)/);

Won't this match the slash since it's a string literal? (Didn't downvote btw)

The / isn't missing. If you use a string then you don't have the slashes.

@JamesMontagne: I am talking from regex perspective since OP tagged question with regex

You need to double escape the backslash: ".signature=(.*)/\\(". This is a valid regex, but it will match the / char though. If you don't need it, simply remove it ;)
