DevGuru HTML Tag: applet


			TAG: applet deprecated 4.0
			<applet> ... </applet> Available in versions: 3.2 Browser compatibility: Explorer 4, 5 Netscape 6 The <applet> tag is officially deprecated effective with HTML 4.0. Instead, you are now to use the object tag. However, this tag remains in wide use on the Internet and is recognized by all major browsers. The applet tag is used to download and execute a Java applet. The applet is treated like an image and is rendered into the flow of the text without a line break. You can define the size of the region (the applet window) in which the applet will appear. By using the attributes for applet, style sheets code, and other HTML tags, you can create a presentation and appearance for the applet in the text flow to suit your needs. Java applets can be very slow to load and may not display in many browsers. Many Java applets require that document-specific parameters be provided to control the execution. You can use the param tag, inserted between the opening and closing applet tags, to define these parameters. The closing tag is mandatory. Core Attributes class id style title Attributes align The align attribute is used to position the applet window with respect to any surrounding text, images, or other applets. alt The alt attribute provides a text message that will be displayed (in place of the applet) on browsers that cannot display an applet. archive The archive attribute is a comma-separated list of URLs of Java classes that must be pre-loaded into the local user cache before the applet can be displayed. code The code attribute is mandatory and specifies the relative URL of the Java class (a .class type file) that must be executed to display the applet. Specifically, the URL is relative to the applet base URL (otherwise the applet will not load). codebase The codebase attribute is used to specify the URL of the directory where the Java class is stored. If the directory is different from where the HTML code is stored, you must use this attribute. height The height attribute is used to set the vertical extent of the applet in pixels. hspace The hspace attribute is used to add additional blank space in pixels to each side of the applet. mayscript The mayscript attribute is only recognized by Netscape. It permits the applet to access JavaScript code. name The name attribute is used to assign a unique string of characters as the name of the applet. object The object attribute is not supported by most browsers. It is the name of a resource where a serialized version of the applet is stored. Do not confuse this attribute with the object tag. vspace The vspace attribute is used to add additional blank space in pixels both above and below the applet. width The width attribute is used to set the horizontal extent of the applet in pixels. This example displays a Java applet clock. Code: <applet codebase="clock/classes" code="JavaClock.class" width="150" height="150"> </applet> Output:
