Is it possible to use JavaScript to click on a particular point or element within a canvas?

Is there a way to trigger a click at a specific point on a canvas without direct access to the code that generates it? I've attempted using coordinates, but haven't had any success. Any alternative suggestions would be appreciated.

UPDATE: To provide more context, the canvas contains multiple elements that are not directly selectable but require clicking. Manually determining their coordinates and attempting to simulate a click does not register as an actual mouse click (the target button is not activated).

I've experimented with x-y coordinates, but they do not generate the desired click simulation. Additionally, I enlisted chatbot help to create a script that could listen for clicks and replicate them, but it did not yield the intended results.

Answer №1

If you're struggling with the mouse event, don't worry - it's a common challenge.

For a solution, consider this approach:


var canvas = document.getElementById('your-canvas-id');

// Adjust the values to fit your specific needs
var x = 150;
var y = 250;

var clickEvent = new MouseEvent('click', {
  clientX: x,
  clientY: y,
});

canvas.dispatchEvent(clickEvent);

If this doesn't resolve the issue, double-check your coordinates or ensure that your canvas ID is correctly specified.
