JavaScript Object Methods
Object Methods in JavaScript can be accessed by using functions. Functions in JavaScript are stored as property values. The objects can also be called without using brackets ().
- In a method, ‘this’ refers to the owner object.
- Additional information can also be added along with the object method.
Syntax:
objectName.methodName()
Properties: A function may be divided into different property values, which are then combined and returned together.
For Ex: The student function contains the properties:
- name
- class
- section
Return Value: It returns methods/functions stored as object properties.
Example 1: This example uses function definition as the property value.
Javascript
// Object creation let student = { name: "Martin" , class: "12th" , section: "A" , studentDetails: function () { return this .name + " " + this .class + " " + this .section + " " ; } }; // Display object data console.log(student.studentDetails()); |
Output
Martin 12th A
Example 2: This example uses storing property values and accessing without bracket ().
Javascript
// Object creation let student = { name: "Martin" , class: "12th" , section: "A" , studentDetails: function () { return this .name + " " + this .class + " " + this .section + " " ; } }; // Display object data console.log(student.studentDetails); |
Output
[Function: studentDetails]
Example 3: Using function definition as property value and accessing with additional details.
Javascript
// Object creation let student = { name: "Martin" , class: "12th" , section: "A" , studentDetails: function () { return this .name + " " + this .class + " " + this .section + " " ; } }; // Display object data console.log( "STUDENT " + student.studentDetails()); |
Output
STUDENT Martin 12th A
