34 Java applets


A Java applet is a small program written in the Java program language.

Browsers can allocate part of their window space to display the Java applet.

Both the older < applet > and newer < object > tags are supported by browsers
for embedding Java applets.

JavaScript programs can communicate with the Java applets using any
methods or properties that the applet makes public . You can also access
the applet through the applets array that is a built - in object of the HTML
document.

< applet name = "myApplet" code = "theapplet.class" codebase = "folder" >
< param name = "parm1" value = "value1" >
< param name = "parm2" value = "value2" >
< param name = "parm3" value = "value3" >
</ applet >

The < applet > tag attributes are :
- name  name that JavaScript can use to communicate with the applet
- code  applet filename
- codebase folder where applet file is located (not needed if in same folder as HTML file

The < param > tags are simply name / value pairs that are passed to the Java
applet.  Use as many (or none) as required by the specific Java applet.

If a Java applet named 'MyApplet' had a public method called 'myFunction' ,
it can be accessed with this code :

document.MyApplet.myFunction()
