Definition and Usage

The open() method opens an output stream to collect the output from any document.write() or document.writeln() methods.

Once all the writes are performed, the document.close() method causes any output written to the output stream to be displayed.

Note: If a document already exists in the target, it will be cleared.

Note: Do not confuse this method with the window.open() method, which opens a new browser window.
