jquery中实现标签切换效果的代码


核心代码:

复制代码 代码如下:

$("ul > li").hover(tab);

function tab() {
$(this).addClass("ll").siblings().removeClass("ll");
var tab = $(this).attr("title");
$("#" + tab).show().siblings().hide();
};

li中和title必须和div中的id一致!
完整的代码
复制代码 代码如下:

<script type="text/javascript" src="jquery-132min2.js"></script>
<script type="text/javascript">
$(function() {
$("ul > li").click(tab);

function tab() {
$(this).addClass("ll").siblings().removeClass("ll");
var tab = $(this).attr("title");
$("#" + tab).show().siblings().hide();
};
});
</script>
</head>
<body>
<ul>
<li class="ll" title="d1">1</li>
<li title="d2">2</li>
<li title="d3">3</li>
</ul>
<div>
<div id="d1">11111</div>
<div id="d2" style="display:none">22222</div>
<div id="d3" style="display:none">33333</div>
</div>

简单的jQuery标签页Simple Tabs w(使用CSS及JQuery)
我知道有很多演示指导如何使用CSS及JQuery创建标签页,但是我还是决定自己动手创建属于我自己的标签页。当然我并不知道技术手法上是否(与别人的)相同,但我希望这个指导很容易懂,甚至对于一个初学者来说搞懂它并不费力。

原文:http://www.sohtanaka.com/web-design/simple-tabs-w-css-jquery/

对那些不是很熟悉JQuery的同学,请看他们的官方网站以获得一个大体的概述,同时你也可以进一步探究这些、这些、还有这些等许多关于JQuery的指导。
Step1. Wireframe – HTML & CSS
Wireframe: a visual representation of the structure of a web page

线框:对网页安排的一种视觉上的描绘

使用无序列表(ul)来呈现你的标签,然后进一步将一个类型(class)为”tab_container”的容器(div)放在它的下方。记住每 一个列表的项(tabs)都有一个”href”的属性值和”.tab_content”div的ID名称一致。这是十分重要的一步!因为我们用 JQuery实现(切换标签页的)动作就要靠它。请记住我为了更容易被你们理解所以使用一般的名称”tab1″。事实上,你必须使用关键字,这样更语义化 (semantic),更有益于你的SEO(搜索引擎优化)。

HTML
复制代码 代码如下:

<ul class=”tabs”>
<li><a href=”#tab1″>Gallery</a></li>
<li><a href=”#tab2″>Submit</a></li>
</ul>

<div class=”tab_container”>
<div id=”tab1″ class=”tab_content”>
<!–Content–>
</div>
<div id=”tab2″ class=”tab_content”>
<!–Content–>
</div>
</div>

如果你之前曾尝试通过CSS创建过标签页,你可能已经在标签边框正确对齐的问题上受到过挫折,以下就是一些大部分朋友碰到的常见问题。

这里我想出来一个解决方案能处理这个讨厌的问题。请看看下面的图片然后看一下CSS,以及它边上的辅助注释,以便更好的理解。

Tabs CSS
复制代码 代码如下:

ul.tabs {
margin: 0;
padding: 0;
float: left;
list-style: none;
height: 32px; /*–Set height of tabs–*/
border-bottom: 1px solid #999;
border-left: 1px solid #999;
width: 100%;
}
ul.tabs li {
float: left;
margin: 0;
padding: 0;
height: 31px; /*–Subtract 1px from the height of the unordered list–*/
line-height: 31px; /*–Vertically aligns the text within the tab–*/
border: 1px solid #999;
border-left: none;
margin-bottom: -1px; /*–Pull the list item down 1px–*/
overflow: hidden;
position: relative;
background: #e0e0e0;
}
ul.tabs li a {
text-decoration: none;
color: #000;
display: block;
font-size: 1.2em;
padding: 0 20px;
border: 1px solid #fff; /*–Gives the bevel look with a 1px white border inside the list item–*/
outline: none;
}
ul.tabs li a:hover {
background: #ccc;
}
html ul.tabs li.active, html ul.tabs li.active a:hover { /*–Makes sure that the active tab does not listen to the hover properties–*/
background: #fff;
border-bottom: 1px solid #fff; /*–Makes the active tab look like it's connected with its content—*/
}


Tab Content CSS
复制代码 代码如下:

.tab_container {
border: 1px solid #999;
border-top: none;
overflow: hidden;
clear: both;
float: left; width: 100%;
background: #fff;
}
.tab_content {
padding: 20px;
font-size: 1.2em;
}

Step2. 让标签动起来 – JQuery
对那些不是很熟悉JQuery的同学,请看他们的官方网站以获得一个大体的概述

以下脚本包含注释,解释了哪只JQuery行为(action)正在被执行。
复制代码 代码如下:

$(document).ready(function() {

//When page loads…
$(“.tab_content”).hide(); //Hide all content
$(“ul.tabs li:first”).addClass(“active”).show(); //Activate first tab
$(“.tab_content:first”).show(); //Show first tab content

//On Click Event
$(“ul.tabs li”).click(function() {

$(“ul.tabs li”).removeClass(“active”); //Remove any “active” class
$(this).addClass(“active”); //Add “active” class to selected tab
$(“.tab_content”).hide(); //Hide all tab content

var activeTab = $(this).find(“a”).attr(“href”); //Find the href attribute value to identify the active tab + content
$(activeTab).fadeIn(); //Fade in the active ID content
return false;
});
});
