书写并添加js代码。 <script src="jquery/jquery-2.2.4.min.js"></script> <script> $(document).ready(function(){ $('.divA1').eq($(this).index()).animate({top:'0'},5) }) $('li').mouseenter(function(){ $(this).css('background-color','rgb(24,68,142)') $('.divA').eq($(this).index()).animate({top:'0'},300) $('.divA').eq($(this).index()).animate({top:'100%'},150) $('.divA1').eq($(this).index()).animate({top:'100%'},150) $(this).find('.divA2').animate({top:'100%'},300) }) $('li').mouseleave(function(){ $('.divA1').eq($(this).index()).animate({top:'0'},150) $('.divA').eq($(this).index()).animate({top:'-100%'},10) $(this).find('.divA2').animate({top:'0'},150) $(this).css('background','rgb(40,100,187)') }) </script>
