/*-----------------------------------------------------------------------------------------/
 * JavaScript Framework Written For JCSTI. Based On JQuery 1.3.2+.
/*----------------------------------------------------------------------------------------*/



/*-----------------------------------------------------------------------------------------/
 * JQuery PlugIn - Slide Show(or, Switch Tab)
 * JQuery滑动切换插件 ver 1.2.0
 *
 * defaultIndex 	- 默认选中的标签索引，从0开始
 * titOnClassName	- 标签选中时的样式
 * titCell			- 自定义标题标签，支持选择符
 * mainCell			- 自定义标题标签，支持选择符
 * delayTime		- 延迟触发时间. 当这个时间小于切换动画效果时间时, 动画将被禁用
 * interTime		- 自动切换时间. 当这个时间大于0时, 标签将定时自动切换
 * trigger			- 滑动触发方式. 默认为click, 可选择mouseover
 * effect			- 切换动画. 默认不使用动画. 目前仅提供fade(淡出), slide(向下展开)两种
 * omitLinks		- 是否忽略带链接标签，默认为否
 * debug			- 调试模式. 默认关闭
