JavaScript Document own method: writeln()
[this page | pdf | back links]
The writeln() method (when applied to the
document object of the JavaScript
DOM) writes
HTML (which can include JavaScript code) to the document, writing a newline
character after each expression.
It is mostly used for
testing, as if it is used after an HTML document is fully loaded it will delete
the existing HTML. Alternatively, it may be used to write to a bespoke output
stream opened by the document.open()
method.
It is essentially the
same as document.write() except
that it adds a new line character after each statement.
It
has the following syntax with the following parameters. It does not return
any value.
document.writeln(expr1, expr2, expr3, …)
