Beginner's Guide to Appending Text with JavaScript: Using an Array in a For Loop
As a beginner in JavaScript, you might find yourself facing various challenges while trying to manipulate the DOM, especially when it comes to appending text elements dynamically. One common task is to append titles from an array to <h2> tags using a loop. In this guide, we will walk through how you can achieve this in a simple and effective way. Let's dive in!
Understanding the Task
You want to take an array of titles and add them as <h2> elements to specific parts of your HTML document. This is a great exercise for learning how to use loops and document querying in JavaScript. Here’s a scenario to consider:
Imagine having an array containing several titles, and you want to add each title to different <h2> elements in your webpage for better content organization.
Example Titles
Title 1
Title 2
Title 3
Title 4
After reading this post, you’ll know how to append each of these titles into the correct HTML structure on your page.
Setting Up Your HTML Structure
Before jumping into the JavaScript code, let's set up our HTML structure. Here's a simple example:

In this structure, we've created several <div> elements with the class .ic-table-h2 where the titles will be appended.
The JavaScript Solution
Now, let's write the JavaScript code that will perform the appending task using a for loop. We will use jQuery for convenience, but we’ll also provide a pure JavaScript solution later.
jQuery Solution
Here's how to append the titles using jQuery:

Explanation of the Code
$(document).ready(): This ensures that the code runs only after the DOM is fully loaded.
Array Declaration: An array called titles holds the strings we want to convert into <h2> tags.
For Loop: We loop through the array using a standard for loop, and at each index, we:
Create a new string addText that contains the current title wrapped in <h2> tags.
Append the new string into the corresponding .ic-table-h2 div using the .eq() method to target the correct element by its index.
Pure JavaScript Solution
If you prefer a pure JavaScript solution without using jQuery, here is how it can be achieved:

Key Differences
In this pure JavaScript version:
We use document.addEventListener("DOMContentLoaded") to ensure the code runs after the DOM is loaded.
We select the elements with document.querySelectorAll and access them directly through the Node List.
Instead of jQuery’s append method, we’re using innerHTML to dynamically add the titles.
Conclusion
Appending text from an array to your HTML dynamically can greatly enhance how you manage your web content display. Whether you choose to use jQuery for its streamlined syntax or stick with pure JavaScript for learning purposes is entirely up to you!
Now that you know the different approaches to append titles, you can experiment with more complex tasks and truly leverage the power of JavaScript.
Happy coding!
