preg_replace equivalent in javascript

Question

But the thing is I want to actually match an pattern and then take the content in it and put it in a other var.

Ok.. i think I'm confusing people more than anything..

this is the code that would work in php.

$intBetweenTheTwoCurlyBraket = preg_replace("/^{([0-9]+)}.*/",'$1',"{132} TestString");

Right now what i have is.

 intBetweenTheTwoCurlyBraket = item.value.replace(/^{([0-9]+)}.*/i,"$1");

But it doesnt work. What im I doing Wrong.

Thanks for any help!

For some reason escaping the curly bracket did the job,..

Thanks for all your inputs My question is now resolved

What is the expected output? `"{132} TestString".replace(/^{([0-9]+)}.*/i,"$1")` would be `"132"` — epascarello, Feb 03 '14 at 19:24
your js regex is already identical to the php version (except the `i` modifier, which isn't necessary). If it's not working, your issue is somewhere else, like not pulling the right value to replace (`item.value`) — CrayonViolent, Feb 03 '14 at 19:27

@NicolasRacine: bracket have special meaning in regexes, You must escape them. — Toto, Feb 04 '14 at 08:24

Escape { and } so use this regex in JS:

/^\{([0-9]+)\}.*/
