Question

I’m trying to prevent information to be copied from a page (for non-technical users of course). I know how to disable selecting text using the mouse. The following jquery code works:

$(function(){
  $.extend($.fn.disableTextSelect = function() {
    return this.each(function(){
      if($.browser.mozilla){//Firefox
        $(this).css('MozUserSelect','none');
      }else if($.browser.msie){//IE
        $(this).bind('selectstart',function(){return false;});
      }else{//Opera, etc.
        $(this).mousedown(function(){return false;});
      });
    });
    $('.noSelect').disableTextSelect();
});

But users can still use Ctrl+A to select the entire page. Any workarounds for this?

Answer 1

this code works for every combination of ctrl+key you want
65 is the ascii code of ‘A’

add 97 if you want to check also for ‘a’

$(function(){   
    $(document).keydown(function(objEvent) {        
        if (objEvent.ctrlKey) {          
            if (objEvent.keyCode == 65) {                         
                objEvent.disableTextSelect();
                return false;
            }            
        }        
    });
});    

Should works, I wrote it directly without testing..
