Disable F5 and Browser Refresh Using JavaScript

Disable F5 and browser refresh using JavaScript

Update A recent comment claims this doesn't work in the new Chrome ... As shown in jsFiddle, and tested on my personal site, this method still works as of Chrome ver 26.0.1410.64 m

This is REALLY easy in jQuery by the way:

jsFiddle

// slight update to account for browsers not supporting e.which
function disableF5(e) { if ((e.which || e.keyCode) == 116) e.preventDefault(); };
// To disable f5
    /* jQuery < 1.7 */
$(document).bind("keydown", disableF5);
/* OR jQuery >= 1.7 */
$(document).on("keydown", disableF5);

// To re-enable f5
    /* jQuery < 1.7 */
$(document).unbind("keydown", disableF5);
/* OR jQuery >= 1.7 */
$(document).off("keydown", disableF5);

On a side note:
This only disables the f5 button on the keyboard.
To truly disable refresh you must use a server side script to check for page state changes.
Can't say I really know how to do this as I haven't done it yet.

On the software site that I work at, we use my disableF5 function in conjunction with Codeigniter's session data. For instance, there is a lock button which will lock the screen and prompt a password dialog. The function "disableF5" is quick and easy and keeps that button from doing anything. However, to prevent the mouse-click on refresh button, a couple things take place.

1. When lock is clicked, user session data has a variable called "locked" that becomes TRUE
2. When the refresh button is clicked, on the master page load method is a check against session data for "locked", if TRUE, then we simple don't allow the redirect and the page never changes, regardless of requested destination

TIP: Try using a server-set cookie, such as PHP's $_SESSION, or even .Net's Response.Cookies, to maintain "where" your client is in your site. This is the more Vanilla way to do what I do with CI's Session class. The big difference being that CI uses a Table in your DB, whereas these vanilla methods store an editable cookie in the client. The downside though, is a user can clear its cookies.

How do I disable the F5 refresh on the browser?

This will disable F5, but not the actual refresh function:

document.onkeydown = function (e) {
  if (e.keyCode === 116) {
    return false;
  }
};

On Chrome/XP, at least.

Can I disable browser refresh in my webapp?

I have a suggestion. There is an answer box in this page.

(Here below with Your Answer label)

• Type some text in it.
• Then refresh this page

When you refresh there is some warning message displayed, I suggest you to display the similar warning message, instead of disabling the refresh functionality.

Disable refresh browser in only one page using angularjs or javascript

document.onkeydown = function(){
  switch (event.keyCode){
        case 116 : //F5 button
            event.returnValue = false;
            event.keyCode = 0;
            return false;
        case 82 : //R button
            if (event.ctrlKey){ 
                event.returnValue = false;
                event.keyCode = 0;
                return false;
            }
    }
}

This code helps you to prevent f5 and ctrl + R functionality
