Question

Hi we are facing the problem with escape key in our web application. If user press the escape key the web application gets stop loading.
I tried using all these with(onkeydown and onkeyup)

document.attachEvent("onkeydown", win_onkeydown_handler);
window.attachEvent("onkeydown", win_onkeydown_handler);
window.document.attachEvent("onkeydown", win_onkeydown_handler);

I cant able detect the escape(KeyCode=27) in my web application .. but i am able to detect refresh,f5 and all other keys

Note: i face this problem in IE

This helps me to prevent escape in iframe

function disableEscapeAndRefresh(){
try{
    if(window.frames && window.frames[0]){
        window.frames[0].focus();
        for (var i_tem = 0; i_tem < window.frames.length; i_tem++){
            if(document.all && document.body.filters)
                window.frames[i_tem].document.onkeydown = new Function("var e=window.frames["+i_tem+"].event; if(e.keyCode==116){e.keyCode=0;alert('Refresh Not Allowed');return false;}if(e.keyCode==27){e.keyCode=0;alert('Escape Not Allowed');return false;};");
        }
    }
}catch(e){

}
}

call this method in iframe onload
