How can I concat variables with that string?

Darn, it killed my script tag. Trying again using square brackets instead of angle brackets:

[script type="appresources/string" id="example]
Hello
I’m a
Really
Multiline
String
[/script]

Here's another idea: if you have a large, multi-line string, just put it inside a script tag.

And then you can get it from javascript like this (example is in jQuery):

var string = $('#example').html();

This has the added benefit of locating all your long strings (templates, etc.) in a better place -- the markup! Roy

Incorrect.

This is using a Firefox only E4X pattern.
Do not teach people this fairly useless technique.

var string = “Hello\n\
I’m a\n\
Really\n\
Multiline\n\
String”;

Try the above.

This will work regardless of browser.
(The “trick” here is the end \ is escaping the new line. Genius).
