What's the cleanest way to write a multiline string in JavaScript?

How does one go onto a new line in writing jQuery code not the actual output of the code, for example:

$('#foo').append('<div id="bla"> '+\n+'
                  </div>');

Something like that.

$('#foo').append('<div id="bla"> \
                 </div>');

The slash (\) escapes the newline, allowing the string to span multiple lines
