how to inject line feeds into dynamically created html (javascript)

I'm creating HTML from javascript c开发者_Go百科ode.

What character(s)/escape codes should I add to the long html to cut the html into smaller lines (in the html source level, not in the rendered html result)?

You can use \n for unix/linux or \n\r for Windows.

Example:

var someString = 'Hello ' + 'Wordl\n';
someString += 'Hello ' + 'Wordl Again\n';
