Refers to the current object. For example, in a form control object event handler, you can pass the object as a parameter to the function: <input type="text" name="ZIP" onchange="validate(this);>" |
|
Inside a custom object constructor, the keyword refers to the object itself, allowing you to assign values to its properties (even creating the properties at the same time): function CD(label, num, artist) {
this.label = label;
this.num = num;
this.artist = artist;
}

|
Inside a function, the this keyword refers to the function object. However, if the function is assigned as a method of a custom object constructor, this refers to the instance of the object in whose context the function executes. |

<input type="text" name="phone" onchange="validate(this.value);"> |
