IE for Windows uses this attribute to assign the Globally Unique ID (GUID) of an ActiveX control.

908 Part III . Document Objects Reference About this object The OBJECT element is intended to be the primary way to add external content (that is, content that the browser itself does not render) to a page. For example, IE/Windows uses it to load ActiveX controls (whether from the server or locally). The OBJECT element is also destined to replace usage of the APPLET and EMBED elements. As with the APPLET element object, scripts can frequently control the programs and plug-ins that get loaded into the browser through the OBJECT tag. Chapter 44 shows you how to do that for common objects. The property listings here are merely for the properties of the element, most of which mimic the attributes available for the OBJECT element. Even though the properties are exposed, they are very rarely scripted, except perhaps to adjust the size of the space occupied by a media controller. Most properties are read-only after their values are set by attributes in the element s tag. But if your scripts are creating the OBJECT element anew, then scripts can set the property values the first time to initialize the object. In the list of properties that begins this object s coverage, several are marked with an asterisk (*). These properties are defined in the W3C DOM Level 2 specification, and placeholders are included in the NN6 code. But as of this writing, there is no indication that these properties are connected. A large set of event handlers for this element (all but onLoadand onScroll) is related to the application of IE/Windows data binding for PARAM elements nested inside an OBJECT element. These events fire when a variety of actions occur to the data source or recordset associated with the program associated with the element.

903Chapter 32 .Embedded Objects Although you cannot query an applet to find out whether it s loaded (as you can with an image), you can rely on the onLoadevent handler of a window to fire only when all applets in the window are loaded and running (with the occasional version- or platform-specific bug in frames, as described in the window.onLoadevent handler discussion in Chapter 16). IE4+ also features an onLoadevent handler for the APPLET element directly, but applets tend to be the last things to load on a page. Therefore, you won t be able to use an applet embedded in a document to help you create the HTML content of that page as it loads, but an applet can provide content for new documents or for modifiable elements of a page. With the highly dynamic object models of IE4+ and NN6, this can lead to all kinds of possibilities. Java applets have also been used to maintain contact with a server after the page has loaded by way of a servlet running on the server. A servlet allows the applet to query or be refreshed with instantaneously updated information without having to reload the page. Of course, getting a sophisticated applet to run in a wide range of browsers and operating systems is a challenge unto itself. A large set of event handlers for this element (all but onLoadand onScroll) is related to the application of IE/Windows data binding for PARAM elements nested inside an APPLET element.

While IE4+ treats both the applet and the APPLET element as objects, NN3 and NN4 offered access to only one property of the APPLET element object (name). In NN6, however, many more APPLET object properties are also scriptable. The fact that the applet, itself, can expose public instance variables and public methods as properties and methods of the applet object means that the scriptable characteristics of an appletobject are highly dependent upon the way the applet was written. You can learn more about how to compose an applet that exposes its innards to JavaScript in Chapter 44. Perhaps the most important point to remember about accessing applets is that you must have them loaded and running before you can address them as objects.
