1408576 - content=content.replace(/^(.*)$/g,'a'+'$1'+'b'); doesn't replace lines in multiline text

Status: VERIFIED INVALID

(Firefox :: Untriaged, defect)

Description

[Jim Michaels]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20170926190823

Steps to reproduce:

content=content.replace(/^(.*)$/g,'a'+'$1'+'b');


Actual results:

replaced 1st line of text only.


Expected results:

the g modifier to /^(.*)$/ should make it a global replace (should do all lines of text in content). i should make it case insensitive. this js syntax is a holdover from sed.

I didn't file this before Mr. Fujusawa.

Looks like your sample code was missing the "m" flag, which makes regular expressions multiline in JS.

(I was able to find this out fairly quickly by typing "JS regexp multiline g" into a search engine.  As others have requested in other bugs you've filed: please test other browsers and do a bit of web searching to sanity-check your assumptions and check if you might just be missing something, before you assume that the problem you're seeing is a Firefox bug that needs reporting.)
