通過前一篇文章 從簡單的Tab標籤到Tab圖片切換 的說明,相關效果也就可以實現了。
1.左右按鈕tab選項卡雙切換
很明顯,左右兩個按鈕是 absolute 布局,另外就是內容部分和Tab標籤部分。
1) 先實現Tab內容和標籤部分的顯示:
HTML代碼:
<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代碼:
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) 然後我們把兩邊的按鈕加上
這裡稍微調整下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>
然後是CSS代碼:
.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;}
顯示效果如下:
3) 然後就是添加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();}
