仿百度联盟对联广告实现代码_广告代码

源码如下：

<style type="text/css">
*{margin:0;padding:0;}
body{height:2000px;}
.floatAd{width:124px;height:299px; text-align:center; position:fixed;margin-left:0;top:109px; _position:absolute; background:url(http://files.jb51.net/demoimg/2014/bg_slide2_120_270.png) no-repeat;}
.floatAd a{display:block;}
.floatAd img{border:none;}
.floatAd .closeAd{width:50px; height:20px; display:block; cursor:pointer;margin:9px 0 0 auto;}
.flAd{left:0;}
.frAd{right:0;}
</style>
<div class="floatAd flAd">
<a href="#" target="_blank"><img src="/static/imghwm/default1.png"  data-src="#"  class="lazy"    style="max-width:90%"  style="max-width:90%" alt="第1张图"></a>
<span class="closeAd"></span>
</div>
<div class="floatAd frAd">
<a href="#" target="_blank"><img src="/static/imghwm/default1.png"  data-src="#"  class="lazy"    style="max-width:90%"  style="max-width:90%" alt="第2张图"></a>
<span class="closeAd"></span>
</div>
<script type="text/javascript">
$(".closeAd").click(function(){
 $(this).parent(".floatAd").hide();
})
/*for ie6*/
function scrollAd(obj) {
	var obj = "." + obj;
	var adTop = $(".floatAd").offset().top;
	//alert(adTop);
	$(window).scroll(function () {
		$(".floatAd").css({
			top : $(window).scrollTop() + adTop
		})
	})
}
$(function () {
	//针对ie6，模拟position:fixed效果
	if ($.browser.msie && parseInt($.browser.version) == 6) {
		scrollAd("floatAd");
	}
})
</script>

我们还可以改下代码，实现“单边展示飘浮广告，多个广告轮播展示”的效果，更改后的源代码：

<style type="text/css">
*{margin:0;padding:0;}
body{height:2000px;}
.floatAd{width:124px;height:299px; text-align:center; position:fixed;margin-left:0;top:109px;right:0; _position:absolute; background:url(http://files.jb51.net/demoimg/2014/bg_slide2_120_270.png) no-repeat;}
.floatAd a{display:block;}
.floatAd img{border:none;}
.floatAd .closeAd{width:50px; height:20px; display:block; cursor:pointer;margin:9px 0 0 auto;}
</style>
<div class="floatAd">
<a href="#" target="_blank"><img src="/static/imghwm/default1.png"  data-src="#"  class="lazy"    style="max-width:90%"  style="max-width:90%" alt="第3张图"></a>
<a href="#" target="_blank" style="display:none;"><img src="/static/imghwm/default1.png"  data-src="#"  class="lazy"    style="max-width:90%"  style="max-width:90%" alt="第4张图"></a>
<span class="closeAd"></span>
</div>
<script type="text/javascript">
$(".closeAd").click(function(){
 $(".floatAd").hide();
})
/*隔时切换飘浮广告*/
function changePic(obj,times){
	var num=0,
		obj =$("." + obj+" >a"),
		times=times*1000,
		len=obj.length;
	//alert(len);
	setInterval(function(){
		num++;
		num=num>len-1&#63;0:num;//console.log(num);
		$(obj).eq(num).show().siblings("a").hide();
		},times)
	}
/*for ie6*/
function scrollAd(obj) {
	var obj = "." + obj;
	var adTop = $(".floatAd").offset().top;
	//alert(adTop);
	$(window).scroll(function () {
		$(".floatAd").css({
			top : $(window).scrollTop() + adTop
		})
	})
}
$(function () {
	//针对ie6，模拟position:fixed效果
	if ($.browser.msie && parseInt($.browser.version) == 6) {
		scrollAd("floatAd");
	}
	//执行定时切换图片广告
	changePic("floatAd",2);//每隔2秒切换一次广告图片展示，间隔时间可控
})
</script>
