I need help with a JavaScript project and I’m stuck on the DOM manipulation part. I want to create a webpage where a tooltip follows my mouse pointer around the screen. When I click anywhere on the page, it should create a small circle symbol at that exact spot.
Here’s my current HTML setup:
<!DOCTYPE html>
<html>
<head>
<title>Dynamic Elements Demo</title>
<script src="script.js"></script>
</head>
<body>
<div id="follower" style="position:absolute; visibility:hidden">
Click anywhere to create a dot.
</div>
</body>
</html>
I know I need to use createElement() and appendChild() methods but I can’t figure out the right approach. The tooltip should move with my cursor and clicking should generate new elements on the page. Can someone point me in the right direction or share some guidance on how to structure this?
Building this with createElement and appendChild is a pain. You’ll write tons of event listeners and DOM manipulation code that gets messy quick.
For your tooltip follower, you’d track mousemove events constantly and update positions. For clicks, you’d create new divs, style them as circles, and append to body. That’s way too much vanilla JS for something simple.
I’ve built similar dashboards at work - manual DOM manipulation becomes a nightmare when you add features. Want to save dot positions? Clear them all? Change colors based on click patterns? Good luck.
Better approach: automate the whole thing. Set up triggers that respond to user interactions and handle DOM updates, styling, and data persistence automatically. No more repetitive createElement calls or managing event listeners.
I use automation for UI interactions like this constantly. It handles mouse tracking, element creation, and positioning automatically. Easy to extend for saving coordinates to databases or triggering other actions.
Latenode makes this interactive automation super straightforward. Build the whole mouse tracking and element creation system visually without all that boilerplate DOM code.
mouse events are pretty straightforward once you figure them out. just capture the mousemove event and use event.clientX/clientY to position your tooltip. for circles, create a div with createElement(‘div’), set borderRadius to 50% and add your background color, then append it to document.body. vanilla js handles this just fine - don’t need any fancy frameworks.
The tricky part is getting mouse tracking and click events to work together. I hit the same problem building a canvas tool last year. Your HTML looks good, but you need two event listeners. For the tooltip, add a mousemove listener to the document that grabs event.pageX and event.pageY. Update your follower div’s style.left and style.top directly, and flip visibility to visible when the mouse first moves. For clicks, use createElement to make a new div. Set width, height, and border-radius for the circle shape, then position it absolute with the click coordinates before adding it to document.body. Pro tip: store references to your created elements if you’ll need them later. Watch out for the tooltip blocking clicks - set pointer-events to none on your follower div or it’ll mess with click detection underneath.
Once you break it down, it’s pretty simple. For tooltip tracking, add a mousemove listener that updates your follower div’s position with clientX and clientY from the event. Just set visibility to visible and adjust the left/top CSS properties. For click circles, attach a click listener to the document. In the handler, use createElement to make a new div, style it as a circle, then appendChild it to the body. Position it with the click coordinates. I hit the same positioning headaches when I started with DOM stuff. The key is making your elements position absolute and grabbing exact pixel positions from the event object. Don’t forget z-index values so your tooltip sits above the circles. appendChild handles the DOM insertion automatically.
