tab切换选项卡js效果 writed by *** 2010.08.13
1.currentid:string 当前被激活菜单的id;
2.otherids:Array() 其它未被激活的id;
3.tabclasses:Array() tab被激活时的样式类+tab未被激活时的样式类,存储两个值即可
*/
function chaneTab(currentid,otherids,tabclasses){
var tagPrefix="tab";
var conPrefix="con";
//显示：
document.getElementById(tagPrefix+currentid).className=tabclasses[0];
document.getElementById(conPrefix+currentid).style.display="block";
//隐藏：
for(var i=0;i<otherids.length;i++){
document.getElementById(tagPrefix+otherids[i]).className=tabclasses[1];
document.getElementById(conPrefix+otherids[i]).style.display="none";
}
}
</script>
