Developing an object that displays animated effects when modifying its properties, such as visibility, and more

Exploring the realm of animations in JavaScript and AngularJS has led me to the idea of creating a unique JavaScript object. Imagine having the ability to define an object where setting an attribute like

obj.visible = true

Would automatically make the object visible, along with other interactive functionalities. Are there any methods to define an object in such a way that it reacts to changes in its attributes? While I am aware of various animation functions that accomplish this, I am curious if it's possible to integrate these functions directly into a JavaScript object.

Answer №1

Implementing a function to trigger when a specific "property" changes can be achieved through utilizing Classes along with getters and setters. Here's an example:

class AnimatedObject {  
  set visible(visibility) {
    // perform actions based on visibility
    console.log("visibility updated to", visibility);
  }
}

let obj = new AnimatedObject();

obj.visible = true;

obj.visible = "foo"

Answer №2

let myObject = { /* insert your object content here */ }

// Check if the 'visible' property in the object is set to 'true' or not
// and adjust the visibility of an element accordingly

if (myObject.visible == 'true') {
    someElement.style.opacity = '1'
} else {
    someElement.style.opacity= '0'
}

In the code snippet above, someElement represents an HTML element tied to your object properties.


Take a look at the Fiddle below for a demonstration of modifying and toggling visibility based on an object property value.

let myObject = { a: '1', b: '3', c: '5', d: '7', visible: 'true' }
let someElement = document.getElementById('specificDiv');
let button = document.querySelector('button');

someElement.textContent = myObject.a + myObject.b + myObject.c + myObject.d;

function confirmVisibility(){
    if (myObject.visible == 'true') {
        someElement.style.opacity = '1'
    } else {
        someElement.style.opacity= '0'
    }
}

function adjustVisibility(){
if (myObject.visible == 'true') {
  myObject.visible = 'false'
  } else {
  myObject.visible = 'true'
  }
  
  confirmVisibility()
}

button.addEventListener('click', adjustVisibility);
#specificDiv {padding: 5px; background-color: green;}
<button>
Click Me
</button>
<div id="specificDiv"></div>
