mouse event bug
Hi!I wrote this code, to demonstrate the mouse event bug:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function mclick(e) {
document.body.innerHTML += '<p>mousedown: ' + e.which + '</p>';
}
function mup(e) {
document.body.innerHTML += '<p>mouseup: ' + e.which + '</p>';
}
</script>
</head>
<body onmousedown="mclick(event);" onmouseup="mup(event);" oncontextmenu="return false;">
<p>buttons:</p>
</body>
</html>
Do the followings:
1: click with the left mousebutton, and hold it down
2: click with the right mousebutton, and hold it down
3: release the left button
4: release the right button
result in Opera:
buttons: mousedown: 1
result in FireFox, Chrome, Safari:
buttons: mousedown: 1 mousedown: 3 mouseup: 1 mouseup: 3
+2 bug:
I wrote oncontextmenu="return false;" into the body, but in Opera the menu will appear.
Mouseup dont works with the middle button
