阅读 (2147)

jQuery UI 实例 - 折叠面板（Accordion）

在一个有限的空间内显示用于呈现信息的可折叠的内容面板。

如需了解更多有关 accordion 部件的细节，请查看 API 文档折叠面板部件（Accordion Widget）。

默认功能

点击头部展开/折叠被分为各个逻辑部分的内容，就像标签页（tabs）一样。您可以选择性地设置当鼠标悬停时是否切换各部分的打开/关闭状态。

基本的 HTML 标记是一系列的标题（H3 标签）和内容 div，因此内容不用通过 JavaScript 即可用。

折叠内容

默认情况下，折叠面板总是保持一个部分是打开的。为了让所有部分都是折叠的，可设置 collapsible 选项为 true。点击当前打开的部分，来折叠它的内容面板。

自定义图标

通过 icons 选项自定义标题图标，icons 选项接受标题默认的和激活的（打开的）状态的 class。使用 UI CSS 框架中的任意 class，或者使用背景图像创建自定义的 class。

填充空间

由于折叠面板是由块级元素组成的，默认情况下它的宽度会填充可用的水平空间。为了填充由容器分配的垂直空间，设置 heightStyle 选项为 "fill"，脚本会自动设置折叠面板的尺寸为父容器的高度。
