- 2007/08/26 Example Of Creating Objects
an example of creating Object in javascript,
taken from http://www.wdvl.com/Authoring/JavaScript/Tutorial/Objects.html
direct instance of an Object
Despite the awkward sound name, a "direct instance of an Object" simply means creating a new single Object, such as myPetDog:
Assigning a method to your new Object is also simple. Assume that you already have coded a function named woof(), which causes a barking sound to play:
myPetDog.woof=woof;
prototype of an Object
Sometimes, you'll want to create a "template" or prototype of an Object. This does not create an actual instance of the Object, but defines the structure of the Object. In the future, then, you can quickly stamp out a particular instance of the Object. Suppose that instead of myPetDog, you created a prototype Object named petDog. This Object could then be a template for a particular pet dog Object. First, create a function which defines the petDog structure:
function petDog(name, breed, year)
{
this.name = name;
this.breed = breed;
this.year = year;
}
{
this.name = name;
this.breed = breed;
this.year = year;
}
Now that the petDog prototype has been set, you can quickly create single instances of a new Object based on the petDog structure:
