<applet>: The Embed Java Applet element - HTML: HyperText Markup Language 编辑
Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The <applet>
element was removed in Gecko 56 and Chrome 47.
Removal is being considered in WebKit and Edge.
The obsolete HTML Applet Element (<applet>
) embeds a Java applet into the document; this element has been deprecated in favor of <object>
.
Use of Java applets on the Web is deprecated; most browsers no longer support use of plug-ins, including the Java plug-in.

- This attribute refers to an archived or compressed version of the applet and its associated class files, which might help reduce download time.
code
- This attribute specifies the URL of the applet's class file to be loaded and executed. Applet filenames are identified by a .class filename extension. The URL specified by code might be relative to the
codebase
attribute. codebase
- This attribute gives the absolute or relative URL of the directory where applets' .class files referenced by the code attribute are stored.
datafld
- This attribute, supported by Internet Explorer 4 and higher, specifies the column name from the data source object that supplies the bound data. This attribute might be used to specify the various
<param>
elements passed to the Java applet. datasrc

elements associated with the applet. height
- This attribute specifies the height, in pixels, that the applet needs.
hspace
- This attribute specifies additional horizontal space, in pixels, to be reserved on either side of the applet.

object
- This attribute specifies the URL of a serialized representation of an applet.
