一、实现效果
二、代码展示
<!-- 导航条点击箭头左右滚动 -->
<script type="text/javascript">
$(function() {
var oPic = $('.picScroll').find('ul');
var oImg = oPic.find('li');
var oLen = oImg.length + 1;
var oLi = oImg.width();
var prev = $(".prev");
var next = $(".next");
oPic.width(oLen * 162); //计算总长度
var iNow = 0;
var iTimer = null;
prev.click(function() {
if (iNow > 0) {
iNow--;
}
ClickScroll();
})
next.click(function() {
if (iNow < oLen - 8) {
iNow++
}
ClickScroll();
})
function ClickScroll() {
oPic.animate({
left: -iNow * 162
})
}
})
</script><div class="nav inner"> <a class="prev"> <i class="iconfont"></i> </a> <div class="picScroll"> <ul> <li><a href="#">公司要闻</a></li> <li><a href="#">党建工作</a></li> <li><a href="#">公司电视台</a></li> <li><a href="#">行业新闻</a></li> <li><a href="#">领导关怀</a></li> <li><a href="#">客户来访</a></li> <li><a href="#">视频新闻</a></li> <li><a href="#">政策法规</a></li> <li><a href="#">111</a></li> <li><a href="#">222</a></li> <li><a href="#">333</a></li> <li><a href="#">444</a></li> </ul> </div> <a class="next"> <i class="iconfont"></i> </a> </div>
.nav-box .nav .prev { float: left; border: 1px solid forestgreen; } .nav-box .nav .next { float: right; border: 1px solid darkgoldenrod; } .nav-box .nav .picScroll { border: 1px solid gold; position: relative; height: 34px; width: 1150px; overflow: hidden; float: left; } .nav-box .nav .picScroll ul { position: absolute; }
三、参考代码
