How do I disable the F5 refresh on the browser?

Question

Preferably using JavaScript but would like to hear other ways too

Answer 1

Actually, you can.. This little routine fixed it all for me..

I needed the other shortcuts, but not F5.

Private Sub WebBrowser1_PreviewKeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles WebBrowser1.PreviewKeyDown
    If e.KeyCode = Keys.F5 Then WebBrowser1.WebBrowserShortcutsEnabled = False Else WebBrowser1.WebBrowserShortcutsEnabled = True
End Sub

Quick and dirty, but it works. Now, I can still use the Ctrl-B, I and U for editing, but I don't have to worry about refresh killing it!!

Enjoy!

Answer 2

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.

Answer 3

1. Write a series of browser extensions which remove refresh functionality.
2. Require in your Terms of Use that your users install (and use) your extension.
3. Prosecute for non-compliance.
4. Profit! (?)

Answer 4

You can't disable refresh.
