Question

Capture and override the "F5" kepress in FLASH

Asked by: acekz

Is there any way to capture the "F5" kepress from within a flash object on a page when it has focus??? I can capture the keypress with javascript in the html so the page won't refresh, but when flash has the focus, the javascript doesn't work anymore. I really need to capture the "F5" in flash, or some workaround because everytime the page is refreshed, the LMS gets a finish command which logs the user out.

what if the user refreshes by clicking the refresh button.

 

by: vickerleungPosted on 2007-02-17 at 20:07:25ID: 18557521

acekz,

You can capture keypress in Flash using get key code like this


var key_obj:Object = new Object();

key_obj.onKeyDown = function()
{
    if (Key.getCode() == 116)
      {
            getURL ("javascript:stop_refresh ();");
      }
};

Key.addListener (key_obj);


The logic is to capture the keypress and try to pass it to javascript,
the function that you have already written.

I am not sure if this works but you may try.

However I do agree with what kiranvj said.
And what if the user is not using IE, say Camino which don't use F5 for refresh?
And what if the user have customized the browser hotkeys?

Cheers
Vicker

Thanks for the comments!
The audience is strictly IE. I have opened the window with constraints.
Also, I know this is jacked, but I have to use Flash 5!!! I don't know that alll your code will work in F5 so maybe you have a similar solution for F5, but I will try it...thanks!!!

 

by: acekzPosted on 2007-02-19 at 06:18:38ID: 18562947

I tried the code you wrote (which i had already tried something similar) except I used F5 functions and it doesn't work. It seems that Flash bypasses this particular event and refreshes the screen no matter what. Is there any way to stop this???

 

by: vickerleungPosted on 2007-02-19 at 06:34:15ID: 18563067

acekz,

I don't write Flash 5, so I can't help.
But you may take a look at this Flash 5 key tutorial to get some idea.

hi acekz,

found out a solution to your problem. Its not related to flash, its purely javascript.
Check this

<HTML>
<HEAD>
<SCRIPT>
function closeIt()
  {
    event.returnValue = "Closing or Refreshing will cause Logout of the current user.";
  }
</SCRIPT>
</HEAD>
<BODY onbeforeunload="closeIt()">

Some text

Some flash

</BODY>
</HTML>

It will ask for confirmation when Refreshing or Closing the page. I think this is the best method for you.

hope this helps
kiranvj

Thanks again, but I already have the javascript solution...the only issue I am having is with Flash. When a Flash object has focus on the page, the javascript solution is bypassed for some reason. I just need a Flash solution or some other solution that can intercept the Flash refresh mechanism.

Hi b0lsc0tt,

I recommend PAQ with points refund since this post contains information which will be useful for many people.

Kiranvj,

Thanks for your reply.  Were you referring to anything specific?  I thought maybe your comment (http:#18564132) but I see 2 problems.  First the title and question would not lead someone to look here for what you provide in that comment.  The other issue is the code only works in IE.  It is very browser specific but the code doesn't make that clear.

Let me know if I didn't look at the post with the useful information.  If it was your comment then feel free to reply to my comment above.  I do think it was a good comment and my recommendation isn't meant to take away from that.

>>First the title and question would not lead someone to look here for what you provide in that comment.

Yes thats right. But still I think the javascript method is a workaround for the actual problem.

 

by: b0lsc0ttPosted on 2007-07-16 at 01:28:10ID: 19493715

Kiranvj,

I'm glad you persisted.  I took another look and can see that the value could outweigh the points I mentioned.

   Changed recommendation:  PAQ with points refunded

Thanks for your comment.  I do hope this will help another in the future even though it wasn't a solution for Acekz.
