Document.writeln()

Writes a string of text followed by a newline character to a document.

Syntax

document.writeln(line);

Parameters

  • line is 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.
