Syntax
document.writeln(line);
Parameters
lineis string containing a line of text.
Example
document.writeln("<p>enter password:</p>");
Notes
document.writeln is the same as document.write but adds a newline.
Note: document.writeln (like document.write) does not work in XHTML documents (you'll get a "Operation is not supported" (
NS_ERROR_DOM_NOT_SUPPORTED_ERR) error on the error console). This is the case if opening a local file with a .xhtml file extension or for any document served with an application/xhtml+xml MIME type. More information is available in the W3C XHTML FAQ.Specifications
