Using JavaScript, enclose an object within an HTML element prior to adding it

I'm currently utilizing a popup lightbox plugin that automatically generates next/prev buttons, but it doesn't enclose them within a container. I am looking to surround these buttons with a containing element, and although I have identified where they are generated in the plugin, I am struggling with how to wrap them as they are created as an object.

The default code for button generation appears as follows:

mfp.container.append(arrowLeft.add(arrowRight));

Prior to adding them to the container, my objective is to encapsulate them within a div with the class mfp-nav. My attempt at achieving this was by using the following code snippet, however, it has not been successful due to the nature of the buttons being objects.

mfp.container.append('<div class="mfp-nav">' + arrowLeft.add(arrowRight) + '</div>');

When rendered on the front-end, the output looks like this:

<div class="mfp-nav">[object Object]</div>

Is there a simple way to wrap this object within a container without having to iterate over the object?

Answer №1

arrowLeft and arrowRight are not strings in HTML format, but rather DOM elements. Thus, simply combining them with other HTML code is not possible. Instead, you need to create the actual DOM elements.

let newDiv = document.createElement('div');
newDiv.classList.add('mfp-nav');
newDiv.append(arrowLeft.add(arrowRight));
mfp.container.append(newDiv);

Answer №2

To achieve this, you can utilize the DOM API:

const newDivElement = document.createElement('div');
newDivElement.className = 'custom-navigation';
newDivElement.appendChild(
  leftArrow.add(rightArrow)
);

mainPopup.container.append(newDivElement)
