How to detect line break with this RegExp

Question

I'm using the RegExp from this SO to shorten string without cutting words. Unfortunately this dont work when there are line breaks in the tested string. Is there a way to shorten string without cutting words and also after at the first line break.

"this is a longish string of \n\n test".replace(/^(.{11}[^\s]*).*/, "$1"); 
//Expected output: "this is a longish"
//Actual output: "this is a longish test"

Can you update your question and give an example of a line break and what you would like the output to be? — Jay, Sep 17 '12 at 20:05

Have you tried inserting another '.replace()' before the one you've got?

Example:

var longString = "this is a longish<br> string of test";
longString = longString.replace(/\n/g, "").replace(/^(.{11}[^\s]*).*/, "$1");

Perhaps something to that effect will help? You may need to play with the formatting a little, as I'm not sure how you want the string to actually end up looking, or how the <br> tags in your page are formatted, etc.

Good luck!

He has updated his question to use `\n`, but the idea is the same. +1 – Jay Sep 17 '12 at 20:18
@quotemyname could you update your answer with this: `replace(/\n/g, "")` – Andreas Köberle Sep 18 '12 at 07:23
Updated. Sorry for the delay, didn't have time to check this until now. – quotemyname Sep 18 '12 at 18:43
@Stev: The multiline modifier (`/m`) does not make `.` match newlines, it makes the `^` and `$` anchors match at line boundaries. You're thinking of the singleline a.k.a. DOTALL modifier (usually `/s`), but doesn't support that mode. – Alan Moore Sep 18 '12 at 19:49
@Alan Moore You're right !! Sorry about posting this ... just deleted it – Stphane Sep 18 '12 at 20:07
