Javascript ctrl-click.

I'm writing a minesweeper clone in javascript and since most browsers won't let you capture right clicks I need some other way to flag a tile.

One way I am considering is control click. I found this code on the web and it seems to work for Internet Explorer

Code:

...
	if (parseInt(navigator.appVersion) > 3) {
		document.onmousedown = mouseDown;
 		if (navigator.appName == "Netscape") 
  			document.captureEvents(Event.MOUSEDOWN);
	}
...

/* this only works for IE at the moment */
function mouseDown(e) {
	if (parseInt(navigator.appVersion)>3) {
		if (navigator.appName == "Netscape") {
			var mString = (e.modifiers+32).toString(2).substring(3,6);
			shiftPressed = (mString.charAt(0)=="1");
			ctrlPressed = (mString.charAt(1)=="1");
			altPressed = (mString.charAt(2)=="1");
  		} else {
   			shiftPressed= event.shiftKey;
   			altPressed = event.altKey;
   			ctrlPressed = event.ctrlKey;
  		}
 	}

 	return true;
}

but as you can see from my implementation at
http://users.cs.cf.ac.uk/B.A.Collins
it just doesn't work in any browser other than IE.

Are there any other ways of capturing a control-click that aren't about 30 years old? Also I probably should've posted this in tech.

Works fine in Opera 8.5

So it does. How do you stop that save image dialog coming up though?

That is very cool!

The Mozilla implementation of the event object also supports the ctrlKey property so:

Code:

function mouseDown(e) 
{
	if (parseInt(navigator.appVersion) > 3)
	{
		var evt = (navigator.appName == "Netscape" ? e : window.event);

		shiftPressed = evt.shiftKey;
		altPressed   = evt.altKey;
		ctrlPressed  = evt.ctrlKey;
 	}

 	return true;
}
