Navigator 2.0, Internet Explorer 3.0
target is a read/write string property of the Link object. It specifies the name of the frame or window in which the URL referred to by the Link object should be displayed. The initial value of this property is specified by the TARGET attribute of the <A> tag that creates the Link object. If this attribute is unset, then the default is for the window containing the Link to be used, so that following a hypertext link overwrites the document that contains the link.
Four special target names are supported. The target named "_blank" specifies that a new, empty browser window should be created and used to display the new URL. The target "_self" is the default; it specifies that the new URL should be displayed in the same frame or window as the link. The target "_parent" specifies that the results should be displayed in the parent frame of the frame that contains the link. Finally, the "_top" target specifies that the new URL should be displayed in the topmost frame--i.e., that all frames should be removed, and the new URL should occupy the entire browser window.
