jquery toggle(listenerOdd, listenerEven)

1. example：

<!DOCTYPE HTML>
<html>
   <head></head>
   <body>
       <div id="chan">click me again!!</div>
       <script type="text/javascript" src="jquery.js"></script>
       <script>
           $(function(){
               $("#chan").toggle(function(event){
                   $(event.target).css('color','red');
               },function(event){
                   $(event.target).css('color','blue');
               });
           });
       </script>
   </body>
</html>

2.每当触发click事件就相互切换
