JavaScript access object method

Use the following syntax to create an object method:

MethodName: function () {Line of Code}

Access the object method with the following syntax:

ObjectName.methodName ()

You would usually describe fullName () as a method of a person object and fullName as a property.

The fullName property is executed as a function after it is called by ().

This example accesses the fullName () method of the person object:

Example

Name = person.fullName ()

If you do not use () when you access the fullName property, the function definition is returned:

Example

Name = person.fullName

Use the built-in method

This example uses the toUpperCase () method of the String object to convert the text to uppercase:

Var message = "Hello world!"

Var x = message.toUpperCase ()

The value of x, after the above code is executed, will be:

HELLO WORLD!

Add a new method

Adding a method to an object is done inside the constructor function:

Example

Function person (firstName, lastName, age, eyeColor) {

This.firstName = firstName

This.lastName = lastName

This.age = age

This.eyeColor = eyeColor

This.changeName = function (name) {

This.lastName = name

}

}

The value of the changeName () function name is assigned to the lastName attribute of person.

Now you can try:

MyMother.changeName ("Jobs")

Make it clear which person you are referring to by "replacing" this,JavaScript with myMother.
