Predefined Classes and Objects

The following are predefined classes and objects in Javascript.

Anchor anchors Applet applets Area Array Body Button Checkbox Date document Error EvalError FileUpload Form forms frame frames Function

Hidden History history Image images Link links location Math MimeType mimetypes navigator Number Object Option options Password Plugin plugins

Radio RangeError ReferenceError RegExp Reset screen Script Select String Style StyleSheet Submit SyntaxError Text Textarea TypeError URIError window

All objects in Javascript inherit common Properties and Methods from the Object class. Those properties and methods are common to all objects.

The above list shows the correct capitalization of the classes (with a capital) and objects (without a capital). You should use the capitalization as shown when referencing these classes and objects. All variations of the words should be avoided though regardless of capitalization as some browsers ignore capitalization.
