JavaScript string with new line - but not using \n
The reason it is not working is because javascript strings must be terminated before the next newline character (not a \n obviously). The reason \n exists is to allow developers an easy way to put the newline character (ASCII: 10) into their strings.
When you have a string which looks like this:
//Note lack of terminating double quote
var foo = "Bob
Your code will have a syntax error at that point and cease to run.
If you wish to have a string which spans multiple lines, you may insert a backslash character '\' just before you terminate the line, like so:
//Perfectly valid code
var foo = "Bob \
is \
cool.";
However that string will not contain \n characters in the positions where the string was broken into separate lines. The only way to insert a newline into a string is to insert a character with a value of 10, the easiest way of which is the \n escape character.
var foo = "Bob\nis\ncool.";
UPDATE: I just came across a wonderful syntax design in JavaScript-ES6 called Template literals. What you want to do can be literally be done using ` (backtick or grave accent character).
var foo = `Bob
is
cool`;
In which case, foo === "Bob\nis\ncool" is true.
Why the designers decided that ` ... ` can be left unterminated, but the " ... " and ' ... ' are illegal to have newline characters in them is beyond me.
Just be sure that the targeting browser supports ES6-specified Javascript implementation.
P.S. This syntax also supports a pretty cool feature that is present in PHP, .NET, and some other scripting languages; namely "Tagged template literals" with which you can build a parameterized string like this:
var a = 'Hello', b = 'World';
console.log(`The computer says ${ a.toUpperCase() }, ${b}!`);
// results in "The computer says HELLO, World!"
Check for \n or \r or \r\n.
There are several representations of newlines, see http://en.wikipedia.org/wiki/Newline#Representations
I think they using \n anyway even couse it not visible, or maybe they using \r. So just replace \n or \r with <br/>
I don't think you understand how \n works. The resulting string still just contains a byte with value 10. This is represented in javascript source code with \n.
The code snippet you posted doesn't actually work, but if it did, the newline would be equivalent to \n, unless it's a windows-style newline, in which case it would be \r\n. (but even that the replace would still work).
