I want to capture the Ctrl – R or F5 shortcut on the browser

  • 0

I want to capture the Ctrl–R or F5 shortcut on the browser to prevent it from performing a browser refresh, but instead perform a custom refresh.

I was able to capture Ctrl–R on Safari and FF using:

document.onkeypress = function(e){
      if ((e.ctrlKey || e.metaKey) && e.keyCode == 114) // Ctrl-R
    e.preventDefault();
}

But that doesn’t work on IE. Is there any way to do this on IE?

Update: For people who are asking why I am doing this in the first place: I just wanted to do a custom app refresh, but wanted to avoid having a “refresh” button because I kinda discourage using the refresh (We have a full page flex app). We ended up switching to F8 because F5 was just too hard to get working on all browsers.

    Open JavaScript

    http://www.openjs.com/scripts/events/keyboard_shortcuts/

    For certain keys (F1, F4), you have to open a new browser window without the address bar.

    Example

    Open a new window, without adornments:

    window.open( 'webpage.html', 'TLA', 
'toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=800,height=665' );

    JavaScript to use the library:

    var FALSE_FUNCTION = new Function( "return false" );

/**
 * Called to disable F1, F3, and F5.
 */
function disableShortcuts() {
  // Disable online help (the F1 key).
  //
  document.onhelp = FALSE_FUNCTION;
  window.onhelp = FALSE_FUNCTION;

  // Disable the F1, F3 and F5 keys. Without this, browsers that have these
  // function keys assigned to a specific behaviour (i.e., opening a search
  // tab, or refreshing the page) will continue to execute that behaviour.
  //
  document.onkeydown = function disableKeys() {
    // Disable F1, F3 and F5 (112, 114 and 116, respectively).
    //
    if( typeof event != 'undefined' ) {
      if( (event.keyCode == 112) ||
          (event.keyCode == 114) ||
          (event.keyCode == 116) ) {
        event.keyCode = 0;
        return false;
      }
    }
  };

  // For good measure, assign F1, F3, and F5 to functions that do nothing.
  //
  shortcut.add( "f1", FALSE_FUNCTION );
  shortcut.add( "f3", FALSE_FUNCTION );
  shortcut.add( "f5", FALSE_FUNCTION );
}

    Inside webpage.html:

    <body onload="disableShortcuts();">
