I need JS that will remove any HTML tags, and then replace newlines with </p><p> and line breaks with <br/>. The string value is coming from a textarea and I understand Linux, Mac and Windows all format newlines differently so I need to take that into account. Thanks!

  • So you want the replace to be different depending on the line endings? Also, \n and \r\n can both be called newlines or line breaks. I think a use case might be beneficial here. – cmptrgeekken Commented Mar 5, 2010 at 21:31

\n and \r\n are equivalent. Linux uses the former, Windows uses the latter.

What you want to do is replace all cases of \n\n and \r\n\r\n with <p></p> and case of simply \n or \r\n with <br />

result = "<p>" + text + "</p>";
result = result.replace(/\r\n\r\n/g, "</p><p>").replace(/\n\n/g, "</p><p>");
result = result.replace(/\r\n/g, "<br />").replace(/\n/g, "<br />");

This assumes there is no html in your text.

I think 

value.replace(/\\n\\n/g, "</p><p>");
value.replace(/\\n/g, "<br/>");

will do the trick.
