How to Convert HTML Elements into a Single String in JavaScript

If you’re working with HTML elements in JavaScript, you might find yourself needing to convert an array of these elements into a single connected string. This is especially common in web development scenarios such as rendering dynamic content or manipulating the DOM in ReactJS.

In this guide, we will explore how to achieve this without losing any of the HTML tags that you have. We will go through the problem, analyze the common pitfalls, and provide a simple, step-by-step solution.

The Problem: Converting HTML to String

Let’s paint the picture. Suppose you have an array of HTML elements, which you have captured via console logs:

This response is not only confusing, but it also does not contain the HTML tags or structure you were expecting. So, how do we convert this array into a proper HTML string while keeping all the tags intact?

The Solution: Using outerHTML

The key to our solution lies in the outerHTML property of HTML elements. This property allows us to get the full HTML representation of each element, including its tags.

Step-by-Step Guide

Here’s a simple solution that involves looping through the array and aggregating each element’s outerHTML.

Initialize a Variable: Start by creating an empty string that will hold all the HTML.
