캔버스 요소에 이벤트 핸들러를 연결하고 모양에 대한 클릭을 감지하는 방법은 무엇입니까?

canvas.addEventListener('click', function() { /* Event handler code */ }, false);

var canvas = document.getElementById('myCanvas');

// Get canvas offset and context
var canvasLeft = canvas.offsetLeft + canvas.clientLeft;
var canvasTop = canvas.offsetTop + canvas.clientTop;
var context = canvas.getContext('2d');

// Array to store element data
var elements = [];

// Add 'click' event listener to canvas
canvas.addEventListener('click', function(event) {
  // Calculate click coordinates relative to canvas
  var x = event.pageX - canvasLeft;
  var y = event.pageY - canvasTop;

  // Check for collision detection against elements
  elements.forEach(function(element) {
    if (y > element.top && y < element.top + element.height
      && x > element.left && x < element.left + element.width) {
      alert('Clicked an element');
      // TODO: Additional actions (e.g., remove element, update canvas)
    }
  });

}, false);
