$(".theatre-item").mouseover(function(){
$(this).addClass('aa');
$(this).siblings().addClass('aa'); //this的兄弟节点添加类aa
$(this).next().removeClass('aa') //this的下一个节点去除类aa
});
$(".theatre-item").mouseout(function(){
$(this).removeClass('aa');
});
});
如果你用的是jquery-ui-accordion的话，可以用这种方法$( ".selector" ).accordion({ active: -1 });你可以试试。
