How to Append a Lap Time to an Empty Div Using jQuery

If you're diving into the world of coding, you might find yourself facing various challenges. One common issue that many new developers encounter is figuring out how to manipulate the DOM (Document Object Model) using JavaScript or jQuery. For instance, when working on a stopwatch project, you might want to append lap times to an empty div. In this guide, we’ll guide you through the solution step by step to help you successfully implement this functionality.

The Problem

You have a working stopwatch, and everything functions perfectly — except for one feature. When you hit the lap button, the lap time is not being added to an empty div as you expected. Normally, you would want to see your lap times displayed somewhere on the screen for tracking purposes. The HTML structure you already have includes a div element where these lap times are supposed to go:

However, your current attempt at appending the lap time isn't working correctly. Here's the function you were trying to use:

In the code above, you're creating a string for myLapDetails, but not converting it into a jQuery DOM element that can be manipulated.

The Solution

Let's break down the solution into clear, manageable steps. We will modify your function to correctly append lap times to the empty div using jQuery. Follow these steps:

Step 1: Create a jQuery Element

Instead of just defining myLapDetails as a string, you need to create a jQuery object from that string. Doing so allows you to manipulate it more effectively. Here's how to adjust your function:

Step 3: Call the Function

To see your changes in action, don't forget to call the addLap function. You could tie it to an event, like a button click, to ensure it runs whenever you press the lap button. For example:
