Removing the new line character from javascript and making the data come in single line

Question

I've the data like

1

2

3

4

after I replace I should get the data as 1234 or 1 2 3 4.

I'm reading the content from one field and storing it one variable. I'm assigning the replaced value to one more variable.

I've tried using

var justiread=comments.read(); var result=justiread.replace(new RegExp( "/\r?\n|\r/", "g" ), "");

even after replacing I'm getting the same as I've entered.

If i want to do the same thing repeatedly say like 7 times. I'm using for loop but the same query is not working. any help pls

 for(h=1;h<=7;h++){ var addjusti=JUSTIFICATION.read(h); var addresult=addjusti.replace(/(\r\n|\n|\r)/gm," "); }

but i'm unable to write it into the field

Anyone please help me out.

str.replace(/(\r|\n)/g,"")

should do the trick.

\r and \n are not always together (depends on EOL style... unix/windows etc).

Don't use new RegExp. Just use the string replace method.

justiread..replace(/(\r\n|\n|\r)/gm,"")

The "g" switch is global replace, "m" means it should happen more than once.

m means something a bit different than that. Kinda totally different, in fact. :P Basically, it means that the string can be multiple lines, and ^ and $ match at the beginning and end of each line. If you don't have a ^ or $ in the pattern, it doesn't much matter.
