There is no way whatsoever to do this, short of malware.

Sorry

There is no way of disabling any of the browser buttons or menus using java script.

As the browser is a software on the client's machine so you cant control a software on a visitors computer from your web application or java script.

If this would be possible then any attacker can easily control your system from web.

If you want that user should not be shown the browser buttons controls then you can open your page in a pop-up window (and while opening the pop-up page set the toolbar property to false from the calling page).

Hi,

http://www.gklein.org/tests/js/disablekey.html

It is not possible to disable the refresh button on the browser but you can prevent the user from hitting the F5 key.

Just copy the code to a javascript file and refer the file by <script type="text/javascript" src="<path>"> </script>

On the Submit button click event after you have updated the values into the database include the following code snippet.

Page.ClientScript.RegisterClientScriptBlock(btnSubmit.GetType(),"DisableKey", "setEventListener(disableKey)",true);

If you really want to filter out whether the user clicked the refresh button on the browser, what you have to do is to preserve a hidden value with some GUID when the page is loaded first time before hitting submit. You can validate with the GUID field after the submission by storing the value into some cache.
function disableKey(event) {
  if (!event) event = window.event;
  if (!event) return;
 
  var keyCode = event.keyCode ? event.keyCode : event.charCode;
 
  //window.status = keyCode;
  //alert(keyCode);
  
  // keyCode for F% on Opera is 57349 ?!
  
  if (keyCode == 116) {
   window.status = "F5 key detected! Attempting to disabling default response.";
   window.setTimeout("window.status='';", 2000);
 
   // Standard DOM (Mozilla):
   if (event.preventDefault) event.preventDefault();
 
   //IE (exclude Opera with !event.preventDefault):
   if (document.all && window.event && !event.preventDefault) {
     event.cancelBubble = true;
     event.returnValue = false;
     event.keyCode = 0;
   }
 
   return false;
  }
}
 
function setEventListener(eventListener) {
  if (document.addEventListener) document.addEventListener('keypress', eventListener, true);
  else if (document.attachEvent) document.attachEvent('onkeydown', eventListener);
  else document.onkeydown = eventListener;
}
 
function unsetEventListener(eventListener) {
  if (document.removeEventListener) document.removeEventListener('keypress', eventListener, true);
  else if (document.detachEvent) document.detachEvent('onkeydown', eventListener);
  else document.onkeydown = null;
}

Open in new window
