Name

Window.open( ): open a new browser window or locate a named window — JavaScript 1.0:

Synopsis

window.open(url, name, features, replace)

Arguments

url

An optional string that specifies the URL to be displayed in the new window. If this argument is omitted, or if the empty string is specified, the new window does not display a document.

name

An optional string of alphanumeric and underscore characters that specifies a name for the new window. This name can be used as the value of the target attribute of <a> and <form> HTML tags. If this argument names a window that already exists, the open( ) method does not create a new window, but simply returns a reference to the named window. In this case, the features argument is ignored.

features

A string that specifies which features of a standard browser window are to appear in the new window. The format of this string is specified in the Window Features section. This argument is optional; if it is not specified, the new window has all the standard features.

replace

An optional boolean argument that specifies whether the URL loaded into the window should create a new entry in the window’s browsing history or replace the current entry in the browsing history. If this argument is true, no new history entry is created. Note that this argument is intended for use when changing the contents of an existing named window.

Returns

A reference to a Window object, which may be a newly created or an already existing one, depending on the name argument. ...
