alert('tabs can not more than 6!');

function addEventHandler(event,ui){
var li = $(ui.tab).parent();
$('<img src="close.gif"/>') //关闭按钮
.appendTo(li)
.hover(function(){
var img = $(this);
img.attr('src','close_hover2.png');

var li = $(ui.tab).parent();
var index = $('#tabs li').index(li.get(0));
$("#tabs").tabs("remove",index);
tabCounter--;
