JavaScript » Objects » Frame
A Frame object is created by using the HTML <FRAME> tag in a Window that contains the <FRAMESET> tag. A frame is an independent window within a parent window (in other words, you can display multiple frames, or windows, on a single screen). It has its own URL and is treated, with a few exceptions, as a Window object by JavaScript (this includes having all the same methods and properties of a Window object). For more information on Frame objects, go to the Window object page.
Properties
- constructor
Syntax: Object.constructor
This specifies a function to create an object's property and is inherited by all objects from their prototype.
- prototype
Syntax: Object.prototype.name = value
This allows the addition of properties and methods to any object.
Methods
- eval
Syntax: Object.eval(string)
The eval method is deprecated as a method of Object, but is still used as a high level function. It evaluates a string of JavaScript in the context of an object.
- toSource
Syntax: Object.toSource()
The toSource method returns a literal representing the source code of an object. This can then be used to create a new object.
- toString
Syntax: Object.toString()
The toString method returns a string representing a specified object.
- unwatch
Syntax: Object.unwatch(property)
This method removes a watchpoint set for an object and property name with the watch method.
- valueOf
Syntax: Object.valueOf()
This method returns a primitive value for a specified object.
- watch
Syntax: Object.watch(property, handlerfunction)
This method adds a watchpoint to a property of the object.
