Question

hi i want to know how to create objects in both javascript and jquery.

something like this.

Person = new Person();
Person.name = "John Doe";
Person.age = "16";

It is possible? Any help will do. Thank you

update #follow-up

If i’m able to create an object using javascript can i pass the object i recently created to a ajax request in jquery?

Answer 1

jQuery is made using (or is) JavaScript, you can do this to work in both:

function Person(){
  this.name = '';
  this.age = 0;
}

Person = new Person();
Person.name = "John Doe";
Person.age = "16";

console.log(Person.name); // John Doe
console.log(Person.age);  // 16

You can pass arguments to constructor function as well:

function Person(name, age){
  this.name = name;
  this.age = age;
}

And add methods inside constructor or prototype too (I prefer latter):

function Person(name, age){
  this.name = name;
  this.age = age;

  this.getName = function(){
     console.log(this.name);
  };

  this.getAge = function(){
     console.log(this.age);
  };

}

Or better using prototype:

Person.prototype.getName = function(){
   console.log(this.name);
};

Person.prototype.getAge = function(){
   console.log(this.age);
};

Now you can create as many instances as you want:

var person1 = new Person();
var person2 = new Person();
person1.name = "John Doe";
person1.age = "16";    
person2.name = "Michael John";
person2.age = "25";    
person1.getName();
person1.getAge();
person2.getName();
person2.getAge();

Result:

John Doe
16
Michael John
25

Good Practices:

• Always capitalize the first letter of constructor function (as in Person) so that people could know that it has to be instantiated with new keyword.

• Generally/mostly it is good idea to add methods via prototype property (as shown above).
