javascript open() methodsyntax
Function:Open a new document and erase the contents of the current document.
Syntax: document.open(mimetype,replace)
##Parameters: mimetype Optional. Specifies the type of document being written. The default value is "text/html". replace Optional. When this parameter is set, it causes new documents to inherit history entries from the parent document.
##Description:This method will erase the content of the current HTML document and start a new document. The new document is written with the write() method or writeln() method.
Note:After calling the open() method to open a new document and using the write() method to set the document content, you must remember to use the close method to close the document and force its content display. A script or event handler that is part of an overwritten document cannot call this method because the script or event handler itself will also be overwritten.
