Opens a new window and loads the document specified by a given URL.
What's New for Microsoft Internet Explorer 6
As of Internet Explorer 6, the _media value of the sName parameter specifies that this method loads a URL into the HTML content area of the Media Bar.
Syntax
Parameters
Return Value
Returns a reference to the new window object. Use this reference to access properties and methods on the new window.
Remarks
By default, the open method creates a window that has a default width and height and the standard menu, toolbar, and other features of Internet Explorer. You can alter this set of features by using the sFeatures parameter. This parameter is a string consisting of one or more feature settings.
When the sFeatures parameter is specified, the features that are not defined in the parameter are disabled. Therefore, when using the sFeatures parameter, it is necessary to enable all the features that are to be included in the new window. If the sFeatures parameter is not specified, the window features maintain their default values. In addition to enabling a feature by setting it to a specific value, simply listing the feature name also enables that feature for the new window.
Internet Explorer 5 allows further control over windows through the implementation of title in the sFeatures parameter of the open method. Turn off the title bar by opening the window from a trusted application, such as Microsoft Visual Basic or an HTML Application (HTA). These applications are considered trusted, because each uses Internet Explorer interfaces instead of the browser.
When a function fired by an event on any object calls the open method, the window.open method is implied.
When an event on any object calls the open method, the document.open method is implied.
Example
This example uses the open method to create a new window that contains Sample.htm. The new window is 200 pixels by 400 pixels and has a status bar, but it does not have a toolbar, menu bar, or address field.
Standards Information
There is no public standard that applies to this method.
