I am trying to replace all multiplines with single line in a string in javascript but none is working . Below is my code :
var str=inputList.replace(/\n/gm,"\n");
input eg
abc,def <3 newlines>
xyz <1 newline>
opp
Expected output:
abc,def <1 newline>
xyz
opp
Actual output:
abc,def<3 newlines>
xyz<1 newline>
opp
Any help is appreciated.
(Edit : simplified version thanks to stribizhev)
If you are trying to replace two or more \\n
with one, try this :
var str = inputList.replace(/\n{2,}/gm,"\n");
{2,} means 2 or more
You are replacing \\n
with \\n
in your code.
Instead do:
var str = inputList.replace(/\n/gm, "");
You are matching just one and replacing it with one. I believe if you just add the +
after the \\n
to match one or more. If you do not want to match just one use {2,}
to match two or more.
var str=inputList.replace(/\n+/g,"\n");
^
or
var str=inputList.replace(/\n{2,}/g,"\n");
