jQuery实现鼠标的移入移出

.classre-Box td.apply-class-hover .ye-tit {
  background: #de763a !important;
}

.classre-Box td.apply-class-hover .classbutton {
  border: 3px solid #de763a;
  color: #de763a;
}

   // 报名班型鼠标移入移出事件
   $('.classre-Box td').hover(
     function () {
       // 鼠标移入时添加apply-class-hoverr类
       $(this).addClass('apply-class-hover')
     },
     function () {
       // 鼠标移入时移出apply-class-hoverr类
       $(this).removeClass('apply-class-hover')
     }
   )
