Create a TypeScript view component that encapsulates an HTMLElement for seamless integration with TweenMax

Looking to develop my own basic view component class that encompasses an HTMLElement or JQuery element, I want to be able to do something similar to this:

var newComponent:CustomComponent = new CustomComponent($('#someDiv'));

TweenMax.to(newComponent, .5, {css:{left:10,...}});

Currently, I have to return the div within my component in order for it to function with TweenMax. However, I aim for my component to be treated just like a jquery or htmlelement so that the code snippet above would function properly.

I've thought about implementing the htmlElement interface, but I can't seem to locate the exact interface containing all the necessary function declarations that I would require.

Appreciate any guidance on this matter. Thanks!

Answer №1

To ensure jQuery does not leak outside of the component and remains seamless for consumers, a slight modification in approach can be implemented.

class CustomComponent {
    public element: HTMLElement; 
    constructor(selector: string){
        this.element = $(selector).get(0); 
    }
}

var customComponent = new CustomComponent('#myid');

TweenMax.to(customComponent.element, .5, {css:{left:10}});

Instead of

this.element = $(selector).get(0);

, consider changing it to

this.element = document.querySelector(selector);

without affecting any existing code that interacts with the component class.

If HTMLElement were structured as a class (as opposed to just an interface), extending it would allow for passing a specialized class to avoid referencing component.element. However, TypeScript defines HTMLElement as an interface-backed declaration which restricts this possibility.

To expand the definition of HTMLElement without introducing a new class:

interface HTMLElement {
    myAdditionalMethod() : string;
}

HTMLElement.prototype.myAdditionalMethod = function () {
    return 'Example';
}

To utilize a class named Element, you can implement the following approach:

class Element{
    element:JQuery; 
    constructor(element:JQuery){
        this.element = element; 
    }
}

TweenMax.to(newElement.element, 1, {css:{opacity:0.8,...}});
