How do I apply line break in javascript

I have a javascript object property that is retrieved from database.

It has something like

This is line one
This is line two
This is line three
This is the line four

My problem is when I want to show them in my html page, there is no break line and they are all cramp together like:

this is line one this is line two this is line three this is the line four

Is there anyway I can show the line break with Javascript only?

Thanks.

Odds are your DB has the data stored with a line-break character.

Because there are three different line break characters used out in the wild, I tend to choose a process that will work on all three.

var line="MSDOS line end\r\nUnix line end\nOld Mac line end\r";
var converted = line.replace(/\r\n|\r|\n/g, "<br>");

Line breaks are just treated as spaces in HTML.

You can display the string in a <pre> tag, then the line breaks are used as line breaks.

You can replace the line breaks with <br> tags:

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

var string = "this is line one this is line two this is line three this is the line four";

var stringNewLine = string.replace('this', '<br/>this');

This is an extreme edge case and will only work with this example.

Replace new lines (\n) with <br> tags:

replace(/\n/g, '<br>');

See example on JSFiddle.

If you're adding this to the HTML Document, <br /> should work. But in only-JS solutions, you should use \r\n for CRLF.
