In my JS code,

JavaScript

var s1 = 'the 1st line';
var s2 = 'the 2nd line';
var s = s1 + '\n' + s2;

The result is: the 1st linethe 2nd line.
Why the '\n' does not work? Thanks.

What do you mean by "not working"? Where are you trying to display the result string?

See the discussion below - the app is for an outlook email. Thanks.

Because this is the web you would use

HTML

< br />

instead of \n.

Please re-post your answer since a part of it looks to be filtered out. Thanks.

I can see it. It's the br tag in html.

Ryan: Thanks for your response. Actually, it is for an email's body rather than a web page. In .Net I can use System.Environment.NewLine. But I don't know how in JS. Any additional hint? Thanks.

In email, element would work perfectly. Most of the email clients would use the email body as HTML and then render it using an HTML engine.

Gmail does that. So, there won't be a trouble. Also, the new line character is old school, C, C++, Java and C# (maybe a few more) and are used in streams of string. Not in rendering.

Can you use that character in HTML? In XAML? No! Because markups don't understand the basic strings, they have their own syntax.

Tested w/ like that: var s = '1st line 2nd line'. When loaded into Outlook, it shows 1st line 2nd line.
Mt email body is pure text format. Thanks.

Outlook usually has a link to display html format. This is an issue with every email client and nothing you can do about it except just provide a link in the email that takes them to a webpage that you can control.

Ryan: Thanks for your explanation. Since the email body in my project will be small, I will use 1 single line.

Afzaal Ahmad Zeeshan 4-Mar-16 14:00pm

That is exactly the explanation of the difference of string and HTML.

ZurdoDev 4-Mar-16 12:56pm

Is the email body in html format?

If the result goes to a text file, use \n for new line.
If the result goes to a HTML file, use   for new line.
