Creating a fresh occurrence of a variable type in JavaScript

How can I create a new instance of variable types in JavaScript?

For example:

var UserControl = { Id: '', Location: { Left: 0, Top: 0, Width: 0, Height: 0 }, Contents: '', Name: '' };

I want to store this UserControl in a JavaScript Array like the following:

UserControl.Id = '1';
UserControl.Location.Left = offset.left;
UserControl.Location.Top = offset.top;
UserControl.Location.Width = offset.left + area.width();
UserControl.Location.Height = offset.top + area.height();
UserControlCollection.push(UserControl);

The issue is that UserControl overwrites the previous entry because it does not create a new instance.

Any ideas on how to resolve this?

Answer №1

To create an object using a constructor function, you can follow this pattern:

function UserSettings() {
  this.UserId = '';
  this.Preference = {
    Theme: 'Light', Language: 'English'
  };
  this.Data = '';
}
