   if(t) return;
   t= setInterval(function(){

    c = i%2 ? o+cls : o;

    if(i==2*times){
     clearInterval(t);
     ele.removeClass(cls);

   };
 $(function(){
  //domready 就闪动
  shake($("#box"),"red",3);

  $("#box1").bind({
   click:function(){
    shake($(this),"red",3);
    return false;
    }
   });
  //通不过mail校验闪动
  $("#mail").blur(
   function(){
     if(!/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/.test($(this).val())) {
