I have changed the source to the following. I found that the mouse up
and down events seem missing if I click quickly. However, the same code
works fine in the desktop environment. For example, the following
"mouseup"is not called if I click very quickly in the area of the first
canvas. I think this could be a bug.
<div>
<script>
function mouseup(event) {
console.log("mouse is down!");
}
</script>
<canvas id="canvas1" width="200" height="100"
onmouseup="mouseup(event)" style="border:1px solid #000000;">
Your Browser does not support HTML5 canvas
</canvas>
<canvas id="canvas2" width="200" height="100" style="border:1px
solid #c3c3c3;">
Your browser does not support the HTML5 canvas tag.
</canvas>
<script>
var c = document.getElementById("canvas1");
var ctx = c.getContext("2d");
ctx.fillStyle = "#FF0000";
ctx.fillRect(0,0,200,100);
var c2 = document.getElementById("canvas2");
var ctx2 = c2.getContext("2d");
ctx2.fillStyle = "#FFFF00";
ctx2.fillRect(0,0,200,100);
</script>
</div>
