Syntax

oNewWindow = window.open( [sURL] [, sName] [, sFeatures] [, bReplace])

Parameters

sURL	Optional. String that specifies the URL of the document to display. If no URL is specified, a new window with about:blank is displayed.
sName	Optional. String that specifies the name of the window. This name is used as the value for the TARGET attribute on a form or an a element. _blank The sURL is loaded into a new, unnamed window. _media   The sURL is loaded into the HTML content area of the Media Bar. Available in Internet Explorer 6 or later. _parent The sURL is loaded into the current frame's parent. If the frame has no parent, this value acts as the value _self. _search Available in Internet Explorer 5 and later. The sURL is opened in the browser's search pane. _self The current document is replaced with the specified sURL . _top sURL replaces any framesets that may be loaded. If there are no framesets defined, this value acts as the value _self.
sFeatures	Optional. This String parameter is a list of items separated by commas. Each item consists of an option and a value, separated by an equals sign (for example, "fullscreen=yes, toolbar=yes"). The following features are supported. channelmode = { yes | no | 1 | 0 } Specifies whether to display the window in theater mode and show the channel band. The default is no. directories = { yes | no | 1 | 0 } Specifies whether to add directory buttons. The default is yes. fullscreen = { yes | no | 1 | 0 } Specifies whether to display the browser in full-screen mode. The default is no. Use full-screen mode carefully. Because this mode hides the browser's title bar and menus, you should always provide a button or other visual clue to help the user close the window. ALT+F4 closes the new window. A window in full-screen mode must also be in theater mode (channelmode). height = number Specifies the height of the window, in pixels. The minimum value is 100. left = number Specifies the left position, in pixels. This value is relative to the upper-left corner of the screen. The value must be greater than or equal to 0. location = { yes | no | 1 | 0 } Specifies whether to display the input field for entering URLs directly into the browser. The default is yes. menubar = { yes | no | 1 | 0 } Specifies whether to display the menu bar. The default is yes. resizable = { yes | no | 1 | 0 } Specifies whether to display resize handles at the corners of the window. The default is yes. scrollbars = { yes | no | 1 | 0 } Specifies whether to display horizontal and vertical scroll bars. The default is yes. status = { yes | no | 1 | 0 } Specifies whether to add a status bar at the bottom of the window. The default is yes. titlebar = { yes | no | 1 | 0 } Specifies whether to display a title bar for the window. This parameter is ignored unless the calling application is an HTML Application or a trusted dialog box. The default is yes. toolbar = { yes | no | 1 | 0 } Specifies whether to display the browser toolbar, making buttons such as Back, Forward, and Stop available. The default is yes. top = number Specifies the top position, in pixels. This value is relative to the upper-left corner of the screen. The value must be greater than or equal to 0. width = number Sets the width of the window, in pixels. The minimum value is 100.
bReplace	Optional. When the sURL is loaded into the same window, this Boolean parameter specifies whether the sURL creates a new entry or replaces the current entry in the window's history list. true sURL replaces the current document in the history list false sURL creates a new entry in the history list.

Return Value
