jquery shortcuts not working on IE -

-

hi using jquery.hotkeys.js plug in key board shortcut. other shortcuts working fine f1 not working expected in ie. on 'f1' keypress binds shortcut being called more 1 time , opens window well.

the code this:

 $(document).bind('keydown', 'f1', function (evt) {         evt.preventdefault();         evt.stoppropagation();         alert('some message');          window.event.keycode = 0;         return false; });

please give me idea this.

thanks

munish

in internet explorer, f1 key cannot cancelled keydown handler. can attach onhelp event instead:

window.onhelp = function () {     return false; }

the firing twice issue possibly bug in plugin code, if it's occurring in internet explorer can work around using onhelp event exclusively:

if ("onhelp" in window) // ie     window.onhelp = function() {         alert("some message");         return false;     } else // others     $(document).bind('keydown', 'f1', function(evt) {         alert('some message');         return false;     });
