jquery中實現(xiàn)標(biāo)簽切換效果的代碼

更新時間：2011年03月01日 23:31:54 作者：

現(xiàn)在比較流行jquery插件，所以既然用了jquery那么就要用好，也不用大量的寫代碼了。

核心代碼：

 
$("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必須和div中的id一致！
完整的代碼

復(fù)制代碼代碼如下:

 
<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> 

簡單的jQuery標(biāo)簽頁Simple Tabs w（使用CSS及JQuery）
我知道有很多演示指導(dǎo)如何使用CSS及JQuery創(chuàng)建標(biāo)簽頁，但是我還是決定自己動手創(chuàng)建屬于我自己的標(biāo)簽頁。當(dāng)然我并不知道技術(shù)手法上是否（與別人的）相同，但我希望這個指導(dǎo)很容易懂，甚至對于一個初學(xué)者來說搞懂它并不費力。

對那些不是很熟悉JQuery的同學(xué)，請看他們的官方網(wǎng)站以獲得一個大體的概述，同時你也可以進一步探究這些、這些、還有這些等許多關(guān)于JQuery的指導(dǎo)。
Step1. Wireframe – HTML & CSS
Wireframe: a visual representation of the structure of a web page

線框：對網(wǎng)頁安排的一種視覺上的描繪

使用無序列表（ul）來呈現(xiàn)你的標(biāo)簽，然后進一步將一個類型（class）為”tab_container”的容器（div）放在它的下方。記住每一個列表的項（tabs）都有一個”href”的屬性值和”.tab_content”div的ID名稱一致。這是十分重要的一步！因為我們用 JQuery實現(xiàn)（切換標(biāo)簽頁的）動作就要靠它。請記住我為了更容易被你們理解所以使用一般的名稱”tab1″。事實上，你必須使用關(guān)鍵字，這樣更語義化（semantic），更有益于你的SEO（搜索引擎優(yōu)化）。

HTML

復(fù)制代碼代碼如下:

 
<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> 

如果你之前曾嘗試通過CSS創(chuàng)建過標(biāo)簽頁，你可能已經(jīng)在標(biāo)簽邊框正確對齊的問題上受到過挫折，以下就是一些大部分朋友碰到的常見問題。

這里我想出來一個解決方案能處理這個討厭的問題。請看看下面的圖片然后看一下CSS，以及它邊上的輔助注釋，以便更好的理解。

Tabs CSS

復(fù)制代碼代碼如下:

 
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

復(fù)制代碼代碼如下:

 
.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. 讓標(biāo)簽動起來 – JQuery
對那些不是很熟悉JQuery的同學(xué)，請看他們的官方網(wǎng)站以獲得一個大體的概述

以下腳本包含注釋，解釋了哪只JQuery行為（action）正在被執(zhí)行。

復(fù)制代碼代碼如下:

 
$(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; 
}); 
});
