sUrl: optional. String. Specify the URL address of the HTML document to be loaded. If no value is specified, a new window for about:blank will be displayed.

sName: optional. String. Specifies the name of the open window. This name can be used for the TARGET attribute of a form or a object. This name can also use the following common name: _media:IE6.0 Open sUrl in the media panel on the left side of the browser.

_blank: Open sUrl in a new window.
_parent: Open within the parent frame of the current frame. If the current frame has no parent frame, this parameter value is equivalent to _self.
_search: IE5.0 opens sUrl in the search panel on the left side of the browser.
_self:sUrl ​​opens in the current window, covering the current document.
_top: Opens sUrl in the topmost window outside all frames. If the current window has no frame structure, this parameter value is equivalent to _self.

sFeatures: Optional. String. Specifies the window decoration style. Use the values ​​below. Separate multiple entries with commas. The setting of this parameter will only take effect when a new browser window is created. channelmode={yes|no|1|0} specifies whether to display the window in channel mode. The default value is no.

fullscreen={yes|no|1|0} specifies whether to display the window in full screen mode. The default value is no. Be careful when using full-screen mode, as this mode hides the browser window's title bar and menus. If the function of closing the window is not provided on the page, the user can use the ALT F4 shortcut key to close the window.

left=number sets the abscissa coordinate of the upper left corner of the window relative to the desktop. The unit is pixel (px).

The default value is yes. toolbar={yes|no|1|0} sets whether to display the toolbar of the browser window. The default value is yes.
bReplace: optional. Boolean. false|true. false: The newly opened document overwrites the current document in the history list. true: Newly opened documents are simply added to the end of the history list.

Return value:
oNewWindow: Object (Element). Returns a reference to the new window object.

Instructions:
Open a new window and load the HTML document specified by sUrl. By default, the new window created by this method has default height, width, menu, toolbar, etc. You can change their settings using the sFeatures parameter.

When the sFeatures parameter is specified, decorative styles that do not appear in the parameter value list will be automatically set to no.

IE5 allows controlling the title bar of an open window. The title bar can be closed by opening a window in a trusted program like Microsoft® Visual Basic or HTML Application (HTA). They are trustworthy because they use Microsoft Internet Explorer as the browser interface.

When the function triggered by an event on the object in the document calls the open method, the open method of the window object is used. When the event on the object in the document directly uses the open method, the open method of the document object is used.
