Re: [qooxdoo-devel] Catching backspace keypress in Qx 0.5.x?

Hi again,

I found I can disable IE's backspace behaviour like this:

            document.>            function blockBackspace() {
                if (window.event && window.event.keyCode == 8) {
                    var t = event.srcElement.tagName;
                    t = t.toLowerCase();
                    if (t == "input") {
                        t = event.srcElement.getAttribute("type");
                        t = t.toLowerCase();
                    }

                    if (t == "text" || t == "password" || t == "textarea") {
                        // allow backspace
                    }
                    else {
                        // block backspace
                        window.event.cancelBubble = true;
                        window.event.returnValue = false;
                        return false;
                    }
                }
            }

But I wonder if I can do the same thing with Qooxdoo 0.5.x?

Hi Sebastian,

With your code (below) pressing the alpha-num keys causes alerts like "caught keystroke: 104". Pressing backspace causes no alert but it does make the browser do a history.back(), which is what I want to disable.

I also notice that pressing F1 to F12, shift, ctrl, alt, insert, delete, home, end, page up/down causes no alert.

Please try the following:

d.addEventListener(QxConst.EVENT_TYPE_KEYPRESS, function(e) {
alert("caught keystroke: " + e.getKeyCode());
});

What is the alert message if you press backspace in IE?
