trouble replacing \n with <br>

[erank99]

When I try to replace the \n from a multi-line textfield it leaves in the line feed and puts in the <br>. I just wan it to replace the \n with the <br>

WhereAt = theText.indexOf("\n");
// Run this do while loop if it is more than -1
do {
theText = theText.replace('\n', '<br>');
WhereAt = theText.indexOf("\n");
} while (WhereAt >-1);

This should replace all \n with <br> in any given string:
(where str is your string)
str = str.replace(/\n/g,'<br>');

Although if you don't want to live in the dark ages of HTML, you might want to consider using XHTML:

(where str is your string)
str = str.replace(/\n/g,'<br />');

For some reason it is not replacing it right. It seems to be leaving in the line feed.

WhereAt = theText.indexOf("\n/g");
// Run this do while loop if it is more than -1
do {
theText = theText.replace('\n/g', '<br>');
WhereAt = theText.indexOf("\n/g");
} while (WhereAt >-1);

When I pull it the value of theText in the text area again it looks like this.

"... the end of the paragraph.
<br>The begining of the new paragraph..."

Any ideas.

You need to replace the CRs (Macintosh), the LFs (Unix), and the CRLFs (Windows)

theText = theText.replace(/(?:\n\r|\n|\r)/g, '<br />');

Note: erank99, don't encapsulate the pattern as a string, that will cause it to not work...leave it just how it's typed. Both boywonder and whammy typed it correctly.
