通过前一篇文章 从简单的tab标签到tab图片切换 的说明,相关效果也就可以实现了。
1.左右按钮tab选项卡双切换
很明显,左右两个按钮是 absolute 布局,另外就是内容部分和tab标签部分。
1) 先实现tab内容和标签部分的显示:
html代码:
<div class="tab-infomations">
<div class="arrows"></div>
<div class="tab-content">
<div class="tab-info">
<div class="info info1">
<p>
we provide a full spectrum of online advertising...
<br />
<a href="#" class="globalbutton"><span>tour our services</span></a>
</p>
</div>
<div class="info info2 hidden">...</div>
<div class="info info3 hidden">... </div>
<div class="info info4 hidden">... </div>
</div>
<div class="tab-thumbs">
<ul>
<li class="selected"><a href="javascript:;">what we do</a></li>
<li><a href="javascript:;">who we are</a></li>
<li><a href="javascript:;">why choose us</a></li>
<li><a href="javascript:;">how we work</a></li>
</ul>
</div>
</div>
</div>
css代码:
body, ul, li { margin: 0; padding: 0; }
body, button, input, select, textarea { font: 12px/1.5 tahoma, arial, \5b8b\4f53; }
ul, ol,li { list-style: none; }
a { text-decoration: none;}
.hidden {display: none;}
/*---------- tab ------------*/
.tab-infomations {position: relative;width: 959px;margin: 10px auto;}
.tab-content {width:912px;height:324px;background: url("../imgs/tab-for-infomation/slidebg.jpg") no-repeat;
overflow: hidden;margin: 0 auto;}
/*---------- tab-thumbs ------------*/
.tab-thumbs{ position: absolute;bottom: 0;}
.tab-thumbs li { float: left;width: 228px;height: 50px;}
.tab-thumbs li a { width: 228px;height: 50px;display: block;color: #ffffff;font-size: 18px;font-family: arial,sans-serif;line-height: 50px;text-align: center; }
.tab-thumbs li.selected a{ cursor: default;text-shadow: 1px 1px 1px #374f10;}
/*---------- tab-info ------------*/
.tab-info { width:912px;height:324px;}
.info {width: 912px;height: 324px;position: absolute;}
.info p{ color:#1d1d1d;font-size: 12px;line-height: 20px;margin-left: 326px;margin-top: 142px;width: 542px; }
.info1 { background: url("../imgs/tab-for-infomation/billboard1.png") no-repeat; }
.info2 { background: url("../imgs/tab-for-infomation/billboard2.png") no-repeat; }
.info3 { background: url("../imgs/tab-for-infomation/billboard3.png") no-repeat; }
.info4 { background: url("../imgs/tab-for-infomation/billboard4.png") no-repeat; }
.globalbutton {background: url("../imgs/tab-for-infomation/btn_right.png") no-repeat top right;display: block;float: left;font-weight: bold;height: 31px;margin-top: 20px;padding-right: 20px;}
.globalbutton span { background: transparent url("../imgs/tab-for-infomation/btn_left.png") no-repeat 0 0;line-height: 18px;line-height: 18px;padding: 7px 0 6px 20px;color: #252525;display: block;}
/*---------- tab-info ------------*/
.arrows { position: absolute;}
效果:
2) 然后我们把两边的按钮加上
这里稍微调整下html:
<div class="tab-infomations">
<div class="arrows">
<a class="arrows-left prev"></a>
<a class="arrows-right next"></a>
</div>
<div class="tab-border">
<div class="tab-content">
...
</div>
</div>
</div>
然后是css代码:
.tab-border { border: 1px solid #cccccc;margin: 0 auto;padding:3px;width: 912px;}
/*---------- tab-arrows ------------*/
.arrows a { display: block;height: 41px;width:41px;top: 143px;z-index: 10;position: absolute;cursor: pointer;}
.arrows-left {background: url("../imgs/tab-for-infomation/arrows.png") no-repeat 0 0;left: 0;}
.arrows-right {background: url("../imgs/tab-for-infomation/arrows.png") no-repeat -41px 0px;right: 0;}
.arrows-left:hover,.arrows-right:hover {background-position-y: -41px;}
显示效果如下:
3) 然后就是添加jquery方法
$(document).ready(function () {
var mindex = 0;
var maxindex = $(".tab-thumbs li").length-1;
$(".tab-thumbs li").click(function () {
var mindex = $(this).index();
changetab(mindex);
});
$(".arrows-right").click(function () {
if(mindex<maxindex){
mindex++;
}else {
mindex = 0;
}
changetab(mindex);
});
$(".arrows-left").click(function () {
if(mindex>0){
mindex--;
}else {
mindex = maxindex;
}
changetab(mindex);
});
})
function changetab(theindex) {
$(".tab-thumbs li").removeclass("selected");
$(".tab-thumbs li").eq(theindex).addclass("selected")
$(".info").stop();
$(".info").fadeout();
$(".info").eq(theindex).fadein();
}
以上就是【little demo】左右按钮tab选项卡双切换的实例代码的详细内容。
