Creating Multiple DIVs with Unique IDs in JavaScript

Creating dynamic web pages often requires generating elements on the fly. One common task is creating multiple <div> elements and assigning them unique IDs. In this post, we'll tackle how to achieve this using JavaScript, specifically when pulling data from a CSV format.

The Problem

If you are working on a project that involves displaying statistics—like state death tolls—you may need to create distinct <div> elements for each state with information like the number of deaths and death rates. However, some may run into issues when trying to programmatically create these elements and ensuring each has a unique identifier.

In the example provided, an attempt to loop through data to create multiple <div>s ran into problems. A redundant loop was created, and inner HTML was not set properly for each state. Let’s fix this and simplify the process.

The Solution

Let’s break down the process of creating multiple <div> elements dynamically and assigning them unique IDs into several clear steps.

Step 1: Fetching Data

The first step is to fetch the data you’ll work with. In our demo, we’ll simulate fetching data from a CSV. The format for the rows contains states, deaths, and death rates, separated by commas.

Step 2: Splitting the Data

Next, we split the data into an array of rows. The result will give us individual state data that we can format into our <div> elements.

Summary

By following these steps, we effectively solved the issue of creating multiple <div> elements with unique IDs based on state names. This process not only organizes the data nicely but also ensures that our DOM manipulation with JavaScript remains efficient and straightforward.
