            封装了一个选项卡,不过已经不像选项卡了-_-!!!brbr 
            现稍微说明下吧,如果不明白的话,旁边有几个例子可能说明起来更清楚些brbr 
            p 
            strongobj.bind = ["a1","td","b1","div"];/strongbr 
            绑定id="a1"下的td标签为菜单,绑定id="b1"下的div标签为内容,简单么?br 
            td标签的数量和div标签的数量必须相同br 
            (若不需要显示内容,只显示菜单话,可以这个在td标签上加td skip="true")br 
            如果id="a1"下的td标签有嵌套表格,这样的话,就不是所有的td都是菜单,这时候需要用下nestingbrbr 
            strongobj.nesting = [false,true,"",""];/strongbr 
            当标签tag有嵌套时,需要用到这个br 
            比如选项卡内容是放在div容器里,而本身这个内容里也有div标签,这时就需要用到br 
            菜单嵌套为false,内容嵌套为true,且会自动判断出内容标签,多数时候这样就可以了br 
            判断方法为,认定getElementsByTagName后第一个标签为内容第一项,其他的就用这个第一项的深度来判断br 
            但有些情况下,这样还是不行br 
            我用后面2个参数做id来指定菜单或者内容的第一项nesting = [false,true,"","q2"];br 
            这样就肯定不会错了(不明白的话看下例子就简单多了)brbr 
            strongobj.index = 0;/strongbr 
            默认显示第几个选项卡,序号从0开始brbr 
            strongobj.style = ["c1","c2","c3"]/strongbr 
            菜单加载的样式的className:br 
            菜单未选中的className是c1br 
            菜单选中的className是c2br 
            菜单onmouseover的className是c3brbr 
            strongobj.overStyle = false;/strongbr 
            选项卡是否有onmouseover, onmouseout变换样式事件[非激活选项卡内容],对应的样式为style[2]brbr 
            strongobj.overChange = false;/strongbr 
            选项卡内容是否用onmouseover, onmouseout直接激活brbr 
            strongobj.menu = false;/strongbr 
            选项卡是菜单类型brbr 
            strongobj.auto = [false, 1000];/strongbr 
            选项卡是否自动播放,播放速度(毫秒)brbr 
            strongobj.creat();/strongbr 
            开始生成选项卡,需要onclick触发事件的话,可以obj.creat(函数名)br 
            所有的都会触发 
            /p

        !--菜单导航的例子-- 
        div class="s" 
          div id="a8" 
            ul 
              li skip="true"首页/li 
              li新闻/li

            diva href="#"蓝色理想/aa href="#"blue idea/a/div 
            div/div 
          /div 
          divstrong注:菜单延时一秒关闭/strongbr这里只是演示,实际可以设置下position什么的。-o-br多级菜单不知道能不能支持,没试过/div 
        /div 
        div class="s" 
            我见过的许多选项卡都不能用来嵌套br但还是有些时候会用到的br 
            所以如您所见,这个演示本身就是一个嵌套,效果还不错 
        /div 
        !--其他应用-- 
        div class="s" 
            比如图片切换什么,不过我太懒了,不写了。。。br 
            这个能干什么,我也不知道。。 
            div id="a9" 
              li新年好啊/li 
              li快过年了/li 
              li天好冷啊/li 
              li大家去抢红包吧/li 
              li红包~!红包~!你在哪里啊?/li 
            /div             
        /div 
        div class="s" 
            选项卡标题(或者菜单)必须和选项卡内容的数量相同,否则会出错br即使选项卡菜单skip="true",内容也要放一个空的标签占位br 
            其他好像暂时没发现什么brbr 
            本来打算加入ajax的,但有些还没想好。br 
            效率的话,应该还行,我这个演示放了几个选项卡,似乎还不错brbr 
            写这个的目的就是以后弄选项卡只要处理样式就可以了,很多选项卡或者切换之类都是大同小异br 
            本来是打算弄些特效在里面,考虑会增加不少代码,所以不加了,简洁点。brbr 
            哦,还有选项卡是附加样式,不会取消原本设置的样式br 
            如左边的下划线是原有的样式 
        /div 
        div class="s"啥都没有1/div 
        div class="s"啥都没有2/div 
        div class="s"啥都没有3/div 
        div class="s"啥都没有4/div
