舌签构造函数
SubShowClass(ID[,eventType][,defaultID][,openClassName][,closeClassName])
version 1.21

参数说明：
	ID: String类型，舌签主容器ID，必须存在的ID，如果为空，必须指定为"none"
	eventType: String类型，默认触发事件，可选，默认为"onmousedown"，参数范围（mousedown,onmouseover,onmouseout,onclick,onmouseup）
	defaultID: Number类型，默认打开第N项，可选，默认为0，范围（0～length-1）
	openClassName: String类型，打开标签项的className，可选，默认为"selected"
	closeClassName: String类型，关闭标签项的className，可选，默认为""

方法1：addLabel(labelID[,contID][,parentBg][,springEvent][,blurEvent])
	功能：
		添加一个标签。
	参数说明：
		labelID: String类型，标签的ID，必须存在的ID，如果为空，必须指定为"none"
		contID: String类型，标签对应的内容ID，可选，如果不存在，标签切换将不对内容进行操作
		parentBg: String类型，当切换到该标签时重置主容器背景CSS，可选，默认为""，格式为CSS样式的background属性，如：url(images/abc.gif) no-repeat 2px 3px #fff
		springEvent: String类型，当切换到该标签时执行的JavaScript代码，可选
		blurEvent: String类型，当标签从打开状态恢复时执行的JavaScript代码，可选
		
方法2：select(num,force)
	功能：
		打开第num项。
	参数说明：
		num: Number类型，要打开项的编号，必须的，从0开始，范围（0～length-1）
		force: 布尔型，如果值等于true强行遍历所有标签，并执行各标签所绑定的springEvent和blurEvent事件。如不指定为true，则只执行新打开标签的springEvent和所要关闭标签的blurEvent事件。
	
方法3：random(num[,num][,num][...])
	功能：
		随机打开其中一项。此方法应该在添加标签(addLabel())之后使用。
	参数说明：
	num: Number类型，每项的随机概率
		参数的个数必须与标签个数相同。如三个标签的舌签按1:1:1随机打开 random(1,1,1)，按1:2:3随机打开 random(1,2,3)
	
方法4：play([spaceTime])
	功能：
		每隔spaceTime毫秒自动切换到下一个标签，鼠标移入到舌签与内容时暂停。此方法应该在添加标签(addLabel())之后使用。
	参数说明：
		spaceTime: Number类型，间隔时间，单位毫秒，默认为5000毫秒(1秒 = 1000毫秒)

方法5：stop()
	功能：
		停止自动播放。

方法6：nextLabel()
	功能：
		切换到下一个标签。如果当前是最后一个标签，则切换到第一个标签。此方法应该在添加标签(addLabel())之后使用。

方法7：previousLabel()
	功能：
		切换到上一个标签。如果当前是第一个标签，则切换到最后一个标签。此方法应该在添加标签(addLabel())之后使用。

例：
//注意：JS必须放在HTML后面，特别要注意要放在内容的后面
var SubShow_01 = new SubShowClass("T_Menu_01","onmouseover",0,"onClassName","offClassName");//String 主ID(必须的)，String 触发事件(onmouseover)，Number 默认打开项(0)，String 打开项className(selectd)，String 关闭项className(空)
SubShow_01.addLabel("S_Menu_00","S_Cont_00","url(images/1.gif) no-repeat 0 0","window.status='1打开了'","window.status='1关闭了'");//String 标签ID(必须的)，String 内容ID(null)，String 重置主容器背景CSS(null)，String 绑定触发事件(null)，String 绑定恢复事件(null)
SubShow_01.addLabel("S_Menu_01","S_Cont_01","url(images/2.gif) no-repeat 0 0","window.status='2打开了'","window.status='2关闭了'");
SubShow_01.addLabel("S_Menu_02","S_Cont_02","url(images/3.gif) no-repeat 0 0","window.status='3打开了'","window.status='3关闭了'");
SubShow_01.random(1,1,1); //随机打开，参数列表为比率，参数数量必须与标签数量相等
SubShow_01.play(5000);

//SubShow_01.select(1); //用来接打开指定项
