Properties & Methods

The properties and methods of an Applet object are the same as

the public fields and methods of the Java applet it represents.

JavaScript code can query and set the Java fields and invoke the

Java methods of the applet.

Arguments

Description

The Arguments object is defined only within a function body, and

within every function body, the local variable

the Arguments object for that function. The Arguments object is

an array whose elements are the values that were passed as argu-

is the second argument, and so on. All values passed as argu-

ments become array elements of the Arguments object, whether or

not those arguments are given names in the function declaration.
