I have an application that makes use of the return key and works fine
in Safari and Firefox. I use the following:
var sendkeyspecial = 0;
var initpage = function () {
MochiKit.Signal.connect(document, "onkeypress", this, "keypress");
MochiKit.Signal.connect(document, "onkeydown", this, "keydown");
MochiKit.Signal.connect(document, "onkeyup", this, "keyup");
};
var isspecialkey = function(e) {
if(e == 13 || e == 8)
return 1;
}
this.keypress = function(e) {
if(e.modifier()['meta'])
return;
var code = e.key().code;
if(code == 0)
code = sendkeyspecial;
if(isspecialkey(code) == 1) {
if(code == 13) { //return
e.stop();
return;
}
if(code == 8) { //backspace
e.stop();
return;
}
}
e.stop();
}
this.keydown = function(e) {
sendkeyspecial = e.key().code;
}
this.keyup = function(e) {
sendkeyspecial = 0;
}
MochiKit.DOM.addLoadEvent(initpage);
This catches all keypresses that don't involve the meta(command) key. I
would probably add special handling for the control key if I was doing
serious development, but this is more of a toy script on my Mac for
now. The sendkeyspecial thing is used to get key repeating to work
properly for special keys in some browsers.
