This is a scriptlet I found in the web. I guess these would be pretty useful in the Ajax context.

Hi, I have a little problem and came across your website as I was trying to look for answers. I’m not a programmer, so I don’t know how to read codes, but find this code of yours I think is close to what I was looking for. Basically what I need is to disable hotkeys of firefox.
Alt F for File
Alt E for Edit
Alt V for View
Alt S for History
Alt B for Bookmarks
Alt Y for Yahoo
Alt T for Tools
Alt H for Help
Ctrl W
I don’t mean to impose, but I have searched all over and have asked people and still couldn’t find the solution to this problem. I was wondering if you might be able to help me in this. Your feedback is very much appreciated and I look forward to hearing from you
Many thanks
Amy from the Philippines
he’lo
check out this script for disable keys
works for safari, mozilla & ofcourse in IE ……
just add key_code in if() u want to disable
function disableKeys(e)
{
// get key code
var key_code = (window.event) ? event.keyCode : e.which;
var ctrl_key = (window.event) ? event.ctrlKey : e.ctrlKey;
// case : if key is enter or escape or F5 or ctrl+n or ctrl+r then avoid it
if ( key_code==13 || key_code==27 || key_code==116 || ctrl_key && (key_code == 78 || key_code == 82) )
{
// case :if it is IE event
if (window.event)
{
window.event.returnValue = null;
event.keyCode=0;
}
// case: if it is firefox event
else
e.preventDefault();
}
}
I am using a pdf control on my page and I want to disable the toolbar of that control, does any one has the solution?
If yes so please post as soon as possible.
And I just want to disable all the browser functions like Refresh button, back and forward buttons etc.
Looking for prompt response.
Thanks and Regards.
Those buttons belong to user. U can’t disable it.
If in IE u can use:
window.history.forward();
is it support to other browser? i.e. NN, Safari, Opera, Chrome.
Sori about my English.
