F5 does not return false in IE

GoogleCodeExporter commented 8 years ago

Hitting F5 in IE does not return false.

Does not work in IE:

$(document).bind("keydown","F5",function(){
    /* do something */
    return false;
});

Does work in IE:

$(document).bind("keydown","F5",function(){
    /* do something */
    if (navigator.appVersion.indexOf('MSIE') != -1) {
        event.keyCode = 0; event.returnValue = false; }
    return false;
});

Why is this not default or how can I do this better?

I've tested the following in IE 7 and didn't get the behaviour you describe. 
e.g. the
page was reloaded after my code was executed.

<html>
    <head>
        <script src="http://jshotkeys.googlepages.com/jquery-1.2.6.js"></script>
        <script
src="http://js-hotkeys.googlecode.com/files/jquery.hotkeys-0.7.8.js"></script>
    </head>
    <body>
    <script>
    $(document).bind("keydown","F5",
        function(event){
            alert("F5");
            event.keyCode = 0; 
            event.returnValue = false;
            return false;
        });

    </script>

That is exactly my point, it shouldn't because you put return false in your 
function.

This will work in IE but not in FF:

<html>
    <head>
        <script src="http://jshotkeys.googlepages.com/jquery-1.2.6.js"></script>
        <script
src="http://js-hotkeys.googlecode.com/files/jquery.hotkeys-0.7.8.js"></script>
    </head>
    <body>
    <script>
    $(document).bind("keydown","F5",
        function(){
            alert("F5");
            event.keyCode = 0; 
            event.returnValue = false;
            return false;
        });
    </script>
</body>
</html>

This will work in FF but not in IE:

<html>
    <head>
        <script src="http://jshotkeys.googlepages.com/jquery-1.2.6.js"></script>
        <script
src="http://js-hotkeys.googlecode.com/files/jquery.hotkeys-0.7.8.js"></script>
    </head>
    <body>
    <script>
    $(document).bind("keydown","F5",
        function(){
            alert("F5");
            return false;
        });
    </script>
</body>
</html>

This will work in both:

<html>
    <head>
        <script src="http://jshotkeys.googlepages.com/jquery-1.2.6.js"></script>
        <script
src="http://js-hotkeys.googlecode.com/files/jquery.hotkeys-0.7.8.js"></script>
    </head>
    <body>
    <script>
    $(document).bind("keydown","F5",
        function(){
            alert("F5");
            if (navigator.appVersion.indexOf('MSIE') != -1) {
                event.keyCode = 0; 
                event.returnValue = false;
            }
            return false;
        });
    </script>
</body>
</html>

But what is the easiest way doing this? And shouldn't be part of the hotkeys 
script
to disable the key after catching? And browser independent?

jQuery itself should do all these for you

From: http://docs.jquery.com/Events/bind

To cancel a default action and prevent it from bubbling up, return false:
$("form").bind("submit", function() { return false; })

To cancel only the default action by using the preventDefault method.
$("form").bind("submit", function(event){
  event.preventDefault();
});

Let me know if it suites you.
Thanks for using hotkeys plugin

Thanks, i haven't seen this page. But, after seeing it, the problem stays 
exactly the
same:

<html>
    <head>
        <script src="http://jshotkeys.googlepages.com/jquery-1.2.6.js"></script>
        <script
src="http://js-hotkeys.googlecode.com/files/jquery.hotkeys-0.7.8.js"></script>
    </head>
    <body>
    <script>
    $(document).bind("keydown","F5",
        function(event){
            alert("F5");
            event.preventDefault();
        });
    </script>
</body>
</html>

This works only for FF and not for IE. (IE7)

Neither of the codes works in IE as you described - That is totally omiting the
Refresh action. In my case, IE showed the alert, and then, reloaded the page.

This is similar to what I described at 
http://code.google.com/p/js-hotkeys/wiki/about

"Firefox is the most liberal one in the manner of letting you capture all 
short-cuts
even those that are built-in in the browser such as Ctrl-t for new tab, or 
Ctrl-a for
selecting all text. You can always bubble them up to the browser by returning 
true in
your handler.

Others, (IE) either let you handle built-in short-cuts, but will add their
functionality after your code has executed. Or (Opera/Safari) will not pass 
those
events to the DOM at all. "
