JavaScript: The Definitive Guide, 5th Edition

Name

HTMLDocument.open( ): begin a new document, erasing the current one — DOM Level 0

Synopsis

void open( );

Description

This method erases the current HTML document and begins a new one, which may be written to with the write( ) and writeln( ) methods. After calling open( ) to begin a new document and write( ) to specify document content, you must always remember to call close( ) to end the document and force its content to be displayed.

This method should not be called by a script or event handler that is part of the document being overwritten, because the script or handler will itself be overwritten.

Example

var w = window.open("");          // Open a new window
var d = w.document;               // Get its HTMLDocument object
d.open( );                            // Open the document for writing
d.write("<h1>Hello world</h1>");  // Output some HTML to the document
d.close( );                           // End the document and display it
