第一步——布局前端页面
第二步——实现搜索框的隐藏与显现
$('input').focus(function(){
$(this).css('box-shadow','0 0 5px #ff6500 inset');
})
$('input').blur(function(){
$(this).css('box-shadow','');
})//选中搜索框时出现边框颜色的变化
$('.box').hover(
function(){
$(this).stop().animate({'top':'2px'},500);
},function(){
$(this).stop().animate({'top':'-65px'},500);
}//第三步——实现导航条的变色
$(this).css('background','#ff6500');第四步——实现导航条下提示条的跟随
$('.one>.tiao').stop().animate({left:100*$x+'px'},250);第五步——实现导航条的下拉菜单
$('.other ul').hide();
$('.other').hover(function(){
$('.other ul').slideDown(100);
$('.one>.tiao').hide();
},function(){
$('.other ul').slideUp(100);
$('.one>.tiao').show();
})
