check checkbox select all / unselect all checked

Hi.
I take so much from this site. that I think I can contribute with this.

Already search for it. Seems like its not yet.
So here my code

//
$(".LINK_OR_BUTTON").click( function(event){
    
      event.preventDefault();
        
      if ( $(":input:checkbox.CLASS:checked", oTable.fnGetNodes()).size() <  oTable.fnSettings().fnRecordsTotal()){
          $(":input:checkbox.CLASS", oTable.fnGetNodes()).attr("checked", "checked");
          $(this).html("[Unselect]").attr("title","[Unselect]");
      } else {
          $(":input:checkbox.CLASS", oTable.fnGetNodes()).removeAttr("checked");
          $(this).html("[Select All]").attr("title","[Select All]");
      }
});
