this statement

 

The this statement refers to the current object.

Syntax

this.property

Example

The this keyword is typically used in object constructors to refer to the current object. In the following example, this refers to the newly created Car object, and assigns values to three properties:

function Car(color, make, model)
{
this.color = color;
this.make = make;
this.model = model;
}
//For client versions of JavaScript, this refers to the window object
//if used outside of the context of any other object.
