css源码
一、输入框的focus和blur
/*搜索框的效果*/
$(function(){
$("#input-search").focus(function(){
var defaultValue=$(this).attr("defaultValue");
if(this.value==defaultValue){
this.value="";
}
}).blur(function(){
if(this.value==""){
this.value=$(this).attr("defaultValue");
}
}).keyup(function(e){
){
alert("回车提交表单");
}
});
})
输入框的focus与blur
二、网页换肤功能（需要结合jquery的cookie插件，来记录用户的选择）
/*换肤的效果,不知道为什么，cookie的效果没有出来*/
function switchSkin(myskin){
$("#skin-css").attr("href","styles/skin/"+myskin+".css");
$("."+myskin).addClass("selected").siblings().removeClass("selected");$
//为了用户下次打开以及刷新的时候，依旧显示上次的皮肤，需要使用cookie来记录当前的选择
$.cookie(});
}
$(function(){
var my_skin=$.cookie("myCssSkin");
alert(my_skin);
if(my_skin){
switchSkin(my_skin);
}
$(".skin li").click(function(){
my_skin=$(this).attr("class");
switchSkin(my_skin);
});
});
jquery实现网页换肤效果
三、广告栏轮播效果（目前实现的是fadeIn和fadeOut的效果，之后研究下如何实现从左到右的滑动效果）
/*大幅广告栏轮播的效果*/
function showImg(index){
$(".carousel-control a").eq(index).addClass("cuttent").siblings().removeClass("cuttent");
$(".carousel-inner div").eq(index).stop(true,true).fadeIn()
.siblings().stop(true,true).fadeOut();
}
$(function(){
//添加广告自动执行效果
//进入广告区域时候，停止动画，否则开始动画;初始化的时候开始动画
;
var adTimer=null;
$(".carousel").mouseenter(function(){
clearInterval(adTimer);
}).mouseleave(function(){
adTimer=setInterval(function(){
showImg(index);
var length=$(".carousel-control a").length;
index++;
){
index=;
}
},);
}).trigger("mouseleave");
//用户手动触发效果
$(".carousel-control a").mouseover(function(){
var index=$(".carousel-control a").index(this);
showImg(index);
}).eq().mouseover();
});
四、gallery的左右滚动效果
/*实现品牌活动的左右滑动效果*/
/*在布局的时候需要注意，ul外围的div的宽度设置正好合适，并且overflow：hidden，内部ul的宽度设置大一些*/
function show_page(index){
$ul_show=$(".brand-gallery");
var li_width=$ul_show.find("li").outerWidth(true);
;
$ul_show.stop(true,false).animate({left:-pageWidth*index},"slow");
}
$(function(){
$(".brand-title li>a").click(function(){
var index=$(".brand-title li>a").index(this);
show_page(index);
//禁止超链接的默认行为
return false;
});
});
gallery左右滚动效果
五、新闻上下滚动的效果
基本思路：通过设置滚动ul的margin-Top来实现，将margin-Top设置为负值，令其上移，当上移动画结束的时候，将margin-top恢复为原来的值，同时将以上去的第一个元素移动到ul的最后一个。
在布局上需要注意：将滚动ul上方的元素设置为relative或者absolute布局，使得当ul设置margin-top为负值的时候，消失在原上方元素的下面。
<div class="main-content">
<aside>
<div class="dongtai">
<h4 class="dongtai-title">
最新动态
</h4>
<ul class="dongtai-content">
<li><a href="#">瑞丽都疯狂推荐的秋装</a></li>

$obj.find("li:first").appendTo($obj);

var scrollTimer;
scrollTimer=setInterval(function(){
scrollNews($ul_news);
},);
});

六、树状目录折叠效果的实现
基本思路：使用next()选择器，以及slideUp和slideDown动画
<div class="global_module procatalog">
<h4 class="dongtai-title" >
产品分类
<span> </span>
</h4>
<ul class="m-treeview">
<li class="m-expanded">
<span>衬衫</span>
<ul>
<li><span>短袖衬衫</span></li>
<li><span>长袖衬衫</span></li>
</ul>
</li>
<li class="m-expanded">
<span>卫衣</span>
<ul>
<li ><span>开襟卫衣</span></li>
<li ><span>套头卫衣</span></li>
</ul>
</li>
<li class="m-expanded">
<span>裤子</span>
<ul>
<li><span>休闲裤</span></li>
<li><span>免烫卡其裤</span></li>
<li><span>牛仔裤</span></li>
<li><span>短裤</span></li>
</ul>
</li>
</ul>
</div>
下方内容折叠html代码
ul.m-treeview{
padding:7px 10px 3px 10px;
border-bottom:7px solid #eee;
}
ul.m-treeview li span{
display:block;
height:22px;
line-height:22px;
cursor:pointer;
}
li.m-expanded{
padding-left:16px;
background:url(../img/treeview-expanded.gif) no-repeat 0 3px;
}
li.m-expanded.collapsed{
background:url(../img/treeview-collapsed.gif) no-repeat 0 3px;
}
.m-expanded ul>li{
padding-left:20px;
background:url(../img/treeview-item.gif) no-repeat 0 3px;
}
内容折叠的css代码
/*树状目录的展开和折叠*/
$(function(){
$(".dongtai-title").toggle(
function(){
$(this).next("ul").slideUp();
$(this).find("span").addClass("up");
},function(){
$(this).next("ul").slideDown();
$(this).find("span").removeClass("up");
}
);
});
$(function(){
$("li.m-expanded>span").toggle(
function(){
$(this).next("ul").slideUp();
$(this).parent("li.m-expanded").addClass("collapsed");
},function(){
$(this).next("ul").slideDown();
$(this).parent("li.m-expanded").removeClass("collapsed");
}
);
});
树状目录折叠的js实现
六、上下滑动广告栏效果
基本思路：
1.在css布局中，将包围ul的外围div的高度固定，并设置overflow:hidden，position:relative;将其包裹的ul，ul中的li设置为绝对布局。
2.上下滑动的过程就是更改ul的top值的过程（注意不是更改li的top值）。
<div class="ads-wrapper">
<ul class="ads">
<li class="ads1"><a href="#"><img src="img/ads/1.gif"/></a></li>
<li class="ads2"><a href="#"><img src="img/ads/2.gif"/></a></li>
<li class="ads3"><a href="#"><img src="img/ads/3.gif"/></a></li>
<li class="ads4"><a href="#"><img src="img/ads/4.gif"/></a></li>
<li class="ads5"><a href="#"><img src="img/ads/5.gif"/></a></li>
</ul>
<ul class="ads-index">
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
</div>
广告栏html代码
/*广告栏的布局*/
.ads-wrapper{
position:relative;
height:150px;
width:590px;
overflow:hidden;
}
ul.ads{
position:relative;
}
.ads .ads1{
position:absolute;
top:0;
left:0;
}
.ads .ads2{
position:absolute;
top:150px;
left:0;
}
.ads .ads3{
position:absolute;
top:300px;
left:0;
}
.ads .ads4{
position:absolute;
top:450px;
left:0;
}
.ads .ads5{
position:absolute;
top:600px;
left:0;
}
ul.ads-index{
position:absolute;
right:15px;
bottom:5px;
}
.ads-index li{
width:17px;
height:17px;
text-align:center;
float:left;
border:1px solid orange;
color:orange;
margin-left:10px;
background-color:#fff;
}
.ads-index li.current{
height:20px;
background-color:orange;
color:#fff;
font-weight:bold;
}
广告栏css样式代码
/*大屏幕广告栏的上下滚动效果实现*/
function scrollAds($ul_ads,index){
var height=$ul_ads.find("li:first").height();
var position=height*index+"px";
//注意是给ul增加动画，而不是给其中的li增加
$ul_ads.stop(true,false).animate({top:"-"+position},1000);
$(".ads-index>li").eq(index).addClass("current").siblings().removeClass("current");
}
$(function(){
var adsTimer;
var index=0;
$("ul.ads").hover(function(){
clearInterval(adsTimer);
},function(){
adsTimer=setInterval(function(){
scrollAds($("ul.ads"),index);
if(index==4){
index=0;
}else{
index++;
}
},3000);
}).trigger("mouseleave");
$(".ads-index>li").mouseover(function(){
index=$(".ads-index>li").index($(this));
scrollAds($("ul.ads"),index);
$(this).addClass("current").siblings().removeClass("current");
}).eq(0).mouseover();
});
广告栏上下滚动效果实现
六、左右滑动效果
基本思路：
1.在css布局中，将包围ul的外围div的宽度固定，并设置overflow:hidden，position:relative;
2.将其包裹的ul设置为绝对布局。
3.左右滑动的过程就是更改ul的left值的过程。
4，对于向左向右按钮的控制，有些类似于数据库的分类查询，设置page_count,page_size,current_page这几个属性，这几个元素的值通过调用width()等获得外围元素的宽度，以及内部li的宽度来获得。
