Window Object

Creating, a window

To create a window use the following syntax:

Window_object_name=]open(“url","Window name"[,"attribute"])

The URL parameter specifies what content appears in the new window. If you specify a value, the browser attempts to locate and display the specified document:

newWindow= window.open(“http://www.java-samples.com", "Home Page","")

Alternatively, you can display a blank page by specifying an empty string ("") as the URL parameter. Use this technique if you want to create an HTML page dynamically using JavaScript:

newWindow = window.open(“", “DynamicPage", “")

newWindow.document.write(“<Hl>Document created using JavaScript.</Hl>") newWindow.document.close ()

Specifying Window Attributes

The windowAttributes parameter is important as you display windows because it

Lets you customize the look of the window you are opening. The window Attributes parameter is optional; not including it gives you a window identical to the current one with respect to attributes.

Attribute	Description
width	Width of window in pixels
height	Height of window in pixels
toolbar	Show/hide browser toolbar
Menubar	Show/hide browser menu bar
Scrollbars	Show/hide browser horizontal and vertical scrollbars
resizable	Allow/disallow resizing of browser window
Status	Show/hide browser status bar
Location	Show/hide URL location box
Directories	Show/hide secondary toolbar (Netscape)
Copyhistory	Copy current window's Go history for new window

The width and height attributes specify the dimensions of the window in pixels.

The remaining attributes are set by using Boolean values: True values are either 1, yes, or the attribute alone; false values are either 0, no, or more simply, leaving it out altogether. For example, if you want to display the new window with only a toolbar and menu bar, you use the following line:

newWindow = window.open("”,"my Window”, "toolbar=l, menubar=l”)

The following syntaxes are also valid:

newWindow = window. open ("", "myWindow” , "toolbar=yes , menubar=yes”)

newWindow = window. open (" “, "myWindow “ , "toolbar, menubar”)

As you can see, you can simply leave out those attributes that are not specified. They are assumed to have false values.
