HomeWeb Front-endHTML TutorialTocify:动态节点目录菜单生成器_html/css_WEB-ITnose

Tocify是一个能够动态生成文章节点目录的jQuery插件。假如我们有一篇很长的文章,文章有多个节点,那么使用Tocify可以根据节点元素动态生成文章目录,点击目录可以平滑滚动到对应的节点,当然当滚动页面时,目录结构会根据当前监听到的节点进行切换到当前目录状态。

查看演示 下载源码

Tocify目前支持Twitter Bootstrap和jQueryUI Themeroller两种主题风格,我们可以根据实际项目任选其中一种风格,另外必要条件jQuery 1.7.2+和jQueryUI Widget Factory 1.8.21+。放心在IE7+即现代浏览器上使用。

引入CSS和Javascript文件

css文件

<link type="text/css" rel="stylesheet" href="jquery.tocify.css" /><link type="text/css" rel="stylesheet" href="bootstrap.css" />

JavaScript文件

<script src="jquery-1.7.2.min.js"></script><script src="jquery-ui-1.9.1.custom.min.js"></script><script src="jquery.tocify.min.js""></script>

HTML结构

创建一个DIV标签,然后给这个标签添加一个ID或者Class,例如:toc

<div id="toc"></div>

这个div#toc它默认是空的内容,它用来动态生成文章目录,那文章目录如何动态关联文章节点的呢?我们还需要把文章节点做一些规划,如:

<div class="wrap">    <h1 id="Tocify">Tocify</h1>    <br />	<section>		<h2 id="节点">节点1</h2>		<p>内容</p>	</section>	<br />	<section>		<h2 id="节点">节点2</h2>		<p>内容</p>	</section>	...</div>

以上的HTML结构代码大家可以修改tocify的CSS文件来满足你项目视觉的需求。

Javascript

使用jQuery选择选中我们的toc元素,然后通过tocify()方法调用Tocify插件。

$(function() {  $("#toc").tocify();});

如此,运行网页,一个动态的文章目录就生成了。

选项设置

Tocify提供了丰富的选项设置,我们可以根据项目实际需求设置不同的选项参数。以下是主要的几个参数选项介绍:
