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! :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;
}
