如何在React中的画布中添加工具提示

Question

我正在尝试在反应js中的画布内添加工具提示。

const canvas = document.getElementById(`myCanvas`);
const ctx = canvas.getContext('2d');

const backgroundImage = new Image();
backgroundImage.src = image.jpg;
backgroundImage.onload = function () {
  ctx.drawImage(backgroundImage, 0, 0);
  if (marker_details.length > 0) {
    marker_details.forEach((marker) => {
      const markerImage = new Image();
      markerImage.title = marker.notes;
      const markerSize = 17;
      markerImage.src = markerImage.jpg;
      ctx.drawImage(markerImage, marker.coordinate_x, marker.coordinate_y, markerSize, markerSize);
    });
  }
};

Image.title无效。如何解决这个问题？
